What TurboMan Claims to Do

The seller markets TurboMan as a natural supplement designed to support masculine health and healthy blood flow related to sexual performance. The recommended dosage is two capsules daily with water, and orders are positioned as one-time purchases without automatic renewal.

The brand states that TurboMan is 100% natural, and in its marketing materials, claims this means there are generally well-tolerated, though individual responses may vary. This claim is not independently substantiated in the captured official materials.

Pricing and Purchase Options

TurboMan is sold in three tiered packages:

  • 2 bottles (60-day supply): $158 plus $9.99 shipping ($79 per bottle)
  • 3 bottles (90-day supply): $207 with free shipping ($69 per bottle)
  • 6 bottles (180-day supply): $294 with free shipping ($49 per bottle)

Shipping displays as $9.99 for the two-bottle order and free shipping for larger packages. The detailed shipping policy indicates $9.95 standard shipping and notes that international fees may vary.

Refund Policy and Guarantees

The seller offers a 180-day refund window from the order date. However, the refund process requires contacting support and returning all empty and unopened bottles. Return postage is the customer's responsibility.

The offer page uses the term “unconditional guarantee,” but the detailed refund policy page specifies these procedural and return requirements, creating a narrower guarantee than the initial language suggests.

Material Limitations: What's Missing

A critical gap limits the usefulness of this review: TurboMan's complete ingredient list and Supplement Facts panel are not disclosed in the brand's official captured materials. This creates several important information gaps:

  • No ingredient verification: We cannot confirm what compounds are in the product or their amounts.
  • No ingredient-specific safety assessment: Without a formula, we cannot assess potential allergies, drug interactions, or contraindications with medications.
  • No third-party testing confirmation: The source materials do not include independent lab testing or GMP certification status.
  • No clinical efficacy evidence: No independent studies specific to this product are referenced.
  • Manufacturer identity not disclosed: The brand name of the company behind TurboMan does not appear in the captured policy pages.

These omissions are significant for any health supplement and should be clarified directly with the seller before purchase.

Who This Is Not For

Anyone taking prescription medications—especially those affecting blood pressure or cardiovascular function—should consult a healthcare provider before using any blood-flow-support supplement. Without the ingredient list, this due diligence is essential.

Similarly, individuals with a history of allergic reactions to supplement ingredients, or those with underlying health conditions, should request a full ingredient disclosure from the seller and review it with a doctor.

Customer Support and Contact Information

The brand provides two contact channels:

  • Email: sac.turboman@gmail.com (listed on the refund policy page)
  • Phone: (877) 2055-636 (listed on the contact page)

BuyGoods processes orders on behalf of the seller.

The Bottom Line

TurboMan is positioned as a natural male sexual-health supplement available at volume-based pricing with a 180-day return option. However, the absence of a disclosed ingredient list and Supplement Facts panel makes it impossible to verify the product's contents, assess safety profiles, or substantiate efficacy claims.

Before ordering, request a complete ingredient disclosure and Supplement Facts label from the seller's support team. If you're taking other medications or have underlying health concerns, consult your healthcare provider with that information in hand.

Steel Power vs. Other Male Performance Supplements

by

Disclosure: This article may contain affiliate links. If you click a link and make a purchase, we may receive a commission at no additional cost to you. All opinions remain our own.

The male performance supplement category is overcrowded, under-regulated in terms of marketing claims, and full of products that are genuinely difficult to compare because most reviews don't do the label work. This comparison gives gym-focused men a practical framework for evaluating Steel Power against other options — based on verified formulas where available, mechanism differences, pricing, and the practical question of who each product is designed for. No product here is evaluated against marketing copy. Comparisons are based on what's on the label.

These statements have not been evaluated by the Food and Drug Administration. No product discussed here is intended to diagnose, treat, cure, or prevent any disease. Consult a qualified healthcare professional before starting any new supplement.

Key Ingredients: L-Citrulline, Pine Bark Extract, L-Carnitine, Maca Root Extract, Grape Skin Extract, Saffron Extract, Zinc (11 mg), Niacin (20 mg).
Price: Not disclosed in article.
Guarantee: 60-day money-back guarantee.
Best For: Gym-focused men seeking vasodilation and nitric oxide support through a disclosed label with verified dosing.
Not Recommended For: Men comparing products solely on marketing claims; note that Tribulus Terrestris and Panax Ginseng appear in website marketing but are not on the verified Supplement Facts panel.

How to Actually Compare Male Performance Supplements

Before you compare products in this category, you need a framework. Most men end up comparing marketing claims — “premium blend,” “clinically studied,” “natural formula” — which tell you nothing useful. Here is what actually matters when comparing male performance supplements from a fitness perspective.

Mechanism clarity: What physiological pathway is the formula designed to support? Nitric oxide and vasodilation? Testosterone support? Adaptogenic stress response? Libido-specific compounds? Different products target different mechanisms, and a clear mechanism is a sign of a formula with an actual design rationale.

Label transparency vs. proprietary blend opacity: A formula that discloses individual ingredient amounts allows you to compare against research-validated doses. A proprietary blend tells you the ingredients are present but not how much of each. Neither is inherently dishonest — proprietary blends protect formulas from copying — but they limit your ability to assess dose relevance.

Price per day vs. price per bottle: A $49 bottle with 30 servings is $1.63 per day. A $19.95 bottle with 30 servings is $0.66 per day. Comparing bottle price is meaningless without comparing serving count and recommended daily dose.

Guarantee terms — the full terms, not the headline: “60-day guarantee” and “60-day money-back guarantee with no return required, no questions asked” are not the same thing. The details matter, and they are almost never in the headline.

Steel Power: The Nitric Oxide Daily Support Option

Steel Power's primary mechanism is nitric oxide support through L-Citrulline and Pine Bark Extract, with a 570 mg proprietary blend across six verified ingredients: L-Citrulline, L-Carnitine, Pine Bark Extract, Maca Root Extract, Grape Skin Extract, and Saffron Extract, plus Zinc (11 mg, 100% DV) and Niacin (20 mg, 125% DV).

Critically: Tribulus Terrestris and Panax Ginseng appear in Steel Power's website marketing descriptions but are not on the verified Supplement Facts panel. This is documented in the Steel Power label breakdown and is worth knowing before comparing the product against competitors. Write your comparisons to the label, not the marketing copy.

Pricing: $79/bottle for 2 bottles, $69/bottle for 3 bottles, $49/bottle for 6 bottles — all 30-capsule bottles (30-day supply). The 60-Day Satisfaction Promise requires an RMA, return of all bottles, customer-paid return shipping, and deducts up to 20% processing fee from approved refunds. Full review: Steel Power review.

Best suited for: Men over 40 who want a once-daily, no-stimulant supplement with a verified NO-support mechanism, are willing to commit to 60 to 90 days of consistent use, and are pairing it with regular exercise and adequate nutrition.

BioBooster: The Testosterone-Plus-NO Formula

BioBooster, also reviewed on BlastFitness.com, takes a different architectural approach to male vitality. Where Steel Power concentrates its formula on the nitric oxide and vasodilation pathway with botanical antioxidant support, BioBooster layers testosterone-support ingredients on top of a similar NO foundation. The BioBooster formula includes Ashwagandha (an adaptogen with published research in testosterone support and stress reduction), Tongkat Ali (documented in research for testosterone and libido support), Vitamin D3 (established correlation with testosterone levels in men), Vitamin B6, Zinc, and L-Citrulline.

The key difference between BioBooster and Steel Power is the hormonal support dimension. Ashwagandha and Tongkat Ali both have more published research behind their testosterone-adjacent mechanisms than several ingredients in Steel Power's blend. Men who are specifically concerned about testosterone support alongside blood flow support may find BioBooster's formula architecture more directly aligned with that goal. See the BioBooster review for full details.

Prolong Power: The Budget Daily Option

Prolong Power, manufactured by NutraKingz and reviewed on BlastFitness.com, is the most affordable option in this comparison at $19.95 per bottle. The formula uses a different ingredient set entirely: Horny Goat Weed (Epimedium Sagittatum), Tongkat Ali, Saw Palmetto, Nettle Root, Sarsaparilla, Orchic Substance, and Boron. This formula is not primarily built around the nitric oxide pathway — it is built around testosterone-support and libido-specific botanical ingredients. Saw Palmetto is specifically included for prostate health support.

For men who want to try a male performance supplement at low financial commitment, Prolong Power's $19.95 price point removes most of the financial risk. The tradeoff is a formula without the L-Citrulline and Pine Bark Extract combination that characterizes the published research on vasodilation support. These are genuinely different formulas targeting overlapping but not identical goals. See the full Prolong Power review for the complete breakdown.

STRATOS: The Hormonal Support and Confidence Formula

STRATOS, also reviewed on BlastFitness.com, positions itself around growth hormone support and confidence, with L-Arginine and GABA as key disclosed ingredients. Its mechanism targets the hormonal dimension of male vitality through a different pathway than Steel Power's vasodilation focus. The STRATOS formula includes L-Arginine directly (rather than the L-Citrulline used in Steel Power), which has lower oral bioavailability due to first-pass metabolism but is the same ultimate NO precursor. GABA is included as a neurological support compound. See the STRATOS review for the full ingredient analysis.

The Practical Decision Framework for Gym-Going Men

After you have verified what is actually on each product's label, the decision comes down to what you are specifically trying to support and what your financial commitment tolerance looks like.

If your primary goal is supporting the blood flow and vasodilation mechanism — the same mechanism relevant to both exercise pump and male sexual function — Steel Power's L-Citrulline and Pine Bark Extract core is the most directly targeted formula in this comparison for that goal. The 570 mg total proprietary blend means individual doses are below acute research-validated thresholds, making it a daily maintenance support approach rather than a high-dose intervention.

If your primary goal is testosterone-adjacent support — you are noticing energy, strength, or mood changes that suggest hormonal shifts — BioBooster's inclusion of Ashwagandha and Tongkat Ali gives you additional mechanism coverage that Steel Power does not provide.

If you want to test the supplement category with minimal financial commitment, Prolong Power's $19.95 price removes most of the financial barrier. It targets different mechanisms, but it is a legitimate starting point for men who are not yet ready to commit to a multi-bottle purchase.

For the complete safety analysis applicable across this category, see the Steel Power side effects guide — the drug interaction considerations for L-Citrulline and PDE5 inhibitors apply to any NO-supporting formula, not just Steel Power.

Steel Power Side Effects: What Men Should Know

Before any supplement earns a place in your daily routine, you need to know the safety profile — not the “generally well tolerated” filler answer, but the specific risks by ingredient, the populations who should not take it without medical clearance, and the drug interactions that are genuinely worth knowing about. This article covers all of that for Steel Power, based on published research on the individual verified ingredients in the formula.

These statements have not been evaluated by the Food and Drug Administration. Steel Power is not intended to diagnose, treat, cure, or prevent any disease. Nothing in this article constitutes medical advice. Always consult a qualified healthcare professional before starting any new supplement, particularly if you take prescription medications or have an existing health condition.

Who Should Not Take Steel Power Without Physician Clearance

The following populations should consult a physician before using Steel Power. This is not a list of absolute contraindications — Steel Power is a dietary supplement, not a pharmaceutical, and the decision about whether to use it in the context of a medical condition belongs to you and your doctor. It is a list of situations where the physiological effects of verified ingredients create meaningful enough risk to warrant a conversation before starting.

Men on antihypertensive medications: L-Citrulline and Niacin both have vasodilatory properties. L-Citrulline increases nitric oxide production, which promotes blood vessel relaxation and can lower blood pressure. Niacin at high doses is a known vasodilator; at 20 mg per capsule the effect is modest but present in sensitive individuals. If you are already taking medication to lower blood pressure, adding vasodilatory supplements may produce additive effects. Discuss with your prescribing physician before starting.

Men taking PDE5 inhibitors (sildenafil, tadalafil, vardenafil): PDE5 inhibitors work by amplifying the nitric oxide signaling pathway in erectile tissue, increasing blood flow through vasodilation. L-Citrulline and Pine Bark Extract also support the nitric oxide pathway. Combining NO-supporting supplements with PDE5 inhibitors may produce additive vasodilation, including potentially dangerous drops in blood pressure. Do not combine Steel Power with any prescribed ED medication without explicit guidance from your prescribing physician. This is the most important drug interaction consideration in this formula.

Men with diagnosed cardiovascular disease: Any supplement that influences nitric oxide production and vasodilation should be discussed with a cardiologist or primary care physician before use if you have coronary artery disease, heart failure, a history of heart attack, stroke, or significant cardiovascular risk factors. This is a precautionary recommendation based on the mechanisms of the verified ingredients — it is not a statement that Steel Power is harmful in cardiac patients, but rather that your doctor needs to assess that question based on your specific medical profile.

Men under 18: Steel Power's labeling explicitly states it is not for use by those under 18 years of age. This applies without exception.

Men with known ingredient allergies: Review the full ingredient list — including excipients (Hypromellose, Microcrystalline Cellulose, Magnesium Stearate, Silicon Dioxide) — before use if you have known food or supplement allergies.

Ingredient-Level Safety Data

L-Citrulline

L-Citrulline is generally well-tolerated in published research at doses from 3,000 mg to 8,000 mg per day — substantially higher than what the 570 mg proprietary blend total allows. At typical research doses, the most commonly reported adverse effects are mild gastrointestinal discomfort (bloating, nausea) in a minority of participants. At the daily maintenance-level doses within Steel Power's blend structure, gastrointestinal effects are unlikely but possible in sensitive individuals.

Pine Bark Extract (Pinus pinaster)

Pinus pinaster bark extract has a favorable safety profile in published research. Studies have used it at doses of 40 mg to 120 mg per day without significant adverse effects. The primary safety consideration is its antioxidant and vasodilatory activity — relevant primarily in the context of antihypertensive medication combinations discussed above. This topic connects to what we cover in Prostate Health 101: What Every Man Should Know.

L-Carnitine

L-Carnitine is generally well-tolerated. At high doses (3,000 mg+), some individuals experience gastrointestinal symptoms and a distinctive body odor caused by gut bacterial metabolism of carnitine to trimethylamine. At the doses present in Steel Power's 570 mg total blend, these effects are unlikely. Men with trimethylaminuria (a rare metabolic disorder affecting TMAO metabolism) should avoid carnitine-containing supplements.

Maca Root Extract

Maca Root is generally recognized as safe. The most commonly reported adverse effects in clinical trials are mild digestive complaints — nausea, abdominal cramping — that tend to resolve with continued use. Maca contains glucosinolates, which theoretically could affect thyroid function in individuals with pre-existing thyroid conditions consuming very large amounts. At supplement doses, this concern has not been established in the published literature, but men with thyroid conditions may wish to flag it with their physician.

Zinc (as Zinc Oxide)

Zinc at 11 mg (100% of Daily Value) is within normal supplementation range. The Tolerable Upper Intake Level (UL) for zinc in adult men is 40 mg per day. Exceeding the UL regularly causes nausea, vomiting, loss of appetite, abdominal cramps, diarrhea, and headaches. Chronic excessive zinc intake depletes copper, which can cause anemia and neurological effects. At 11 mg from Steel Power, you have significant headroom — but men taking multiple zinc-containing supplements or eating high-zinc diets (oysters, red meat, fortified cereals) should be mindful of total daily zinc intake and avoid stacking beyond the UL.

Vitamin B3 (Niacin) — 20 mg

At 20 mg — less than 10% of the dose associated with niacin flush in most individuals — flushing is possible in people who are particularly sensitive to niacin but is not expected as a routine occurrence. Taking Steel Power with food may further reduce any likelihood of mild niacin-related skin flushing. At therapeutic doses (500 mg to 3,000 mg), niacin requires medical supervision due to effects on liver enzymes and lipid metabolism. At 20 mg, these concerns are not applicable.

Grape Skin Extract and Saffron Extract

Grape Skin Extract (Vitis vinifera) has a favorable safety profile in dietary supplement use. Its resveratrol and anthocyanin content are well-studied antioxidants with no significant adverse effects documented at supplement doses. Saffron Extract at doses used in research (30 mg to 100 mg per day) has been well-tolerated in trials. As the last-listed ingredient in the proprietary blend, its dose in Steel Power is the smallest of the six. No significant adverse effects are expected at this dose level.

The Refund Consideration as a Safety Backstop

Steel Power's 60-Day Satisfaction Promise exists from the purchase date. If you experience any adverse effects after starting Steel Power, discontinue use and contact customer support for the return process. The 60-day window provides time to assess how your body responds before the guarantee period closes. Review the full refund terms — including the up-to-20% processing fee and return shipping cost — at steelpower.shop before ordering. For the full policy breakdown, see the Steel Power review.

Frequently Asked Questions

Can Steel Power affect blood pressure?

L-Citrulline and Niacin both have vasodilatory properties that may lower blood pressure in some individuals. Men taking blood pressure medications should consult their physician before taking Steel Power, as the combination may produce additive blood pressure lowering effects. This is a precautionary consideration, not a contraindication, but requires a conversation with your doctor if you are on antihypertensive therapy.

Is Steel Power safe to take with ED medications?

Steel Power is not a pharmaceutical and is not a PDE5 inhibitor. However, L-Citrulline and Pine Bark Extract both support nitric oxide production and vasodilation — the same pathway PDE5 inhibitors amplify. Combining NO-supporting supplements with PDE5 inhibitors may produce additive vasodilation and potentially dangerous drops in blood pressure. Do not combine Steel Power with any ED medication without explicit guidance from your prescribing physician.

Can I take Steel Power if I have a heart condition?

Men with cardiovascular disease should consult their physician before using any supplement that influences nitric oxide pathways. Steel Power has not been studied in men with cardiac conditions. Your cardiologist is the correct person to assess safety for your specific situation.

What are the most common side effects of Steel Power ingredients?

Based on published research on individual ingredients: L-Citrulline at high doses has been associated with mild gastrointestinal discomfort. Niacin at 20 mg may cause mild flushing in sensitive individuals, especially on an empty stomach. Maca Root has been reported to cause mild digestive upset. Zinc at 11 mg is within normal range; excess zinc from multiple sources can cause nausea and copper depletion. Individual responses vary. Discontinue use and consult a physician if you experience any concerning symptoms.

If you want to evaluate a supplement properly, you start with the label — not the marketing page. The marketing page is the company's sales pitch. The Supplement Facts panel is the legal disclosure. When the two don't match, the label wins. This article gives you a line-by-line breakdown of what the Steel Power Supplement Facts panel actually says, what each listed ingredient is, what the published research at the individual compound level suggests about it, and why two ingredients that appear in Steel Power's website marketing descriptions are not on the verified panel.

These statements have not been evaluated by the Food and Drug Administration. Steel Power is not intended to diagnose, treat, cure, or prevent any disease. Consult a qualified healthcare professional before starting any new supplement.

The Label/Marketing Discrepancy: What You Need to Know First

Before the ingredient-by-ingredient breakdown, this needs to be stated clearly. The Steel Power website's ingredient section and FAQ describe and reference: L-Citrulline, L-Carnitine, Pine Bark Extract, Maca Root Extract, Tribulus Terrestris, and Panax Ginseng. The verified Supplement Facts panel lists: L-Citrulline, L-Carnitine, Pine Bark Extract, Maca Root Extract, Grape Skin Extract, and Saffron Extract.

Tribulus Terrestris and Panax Ginseng do not appear on the Supplement Facts panel. Grape Skin Extract and Saffron Extract appear on the Supplement Facts panel but are not prominently featured in the website's ingredient descriptions. Multiple third-party reviewers on the SERP are citing Tribulus and Ginseng as active Steel Power ingredients — that is incorrect based on the verified label. This page writes to the label only.

Serving Size and Container Information

Serving Size: 1 capsule. Servings Per Container: 30. Capsule shell: Hypromellose (vegetable capsule). Other ingredients: Microcrystalline Cellulose, Magnesium Stearate, Silicon Dioxide.

The vegetable capsule makes Steel Power suitable for men who avoid gelatin-based supplements. Microcrystalline Cellulose is a standard filler/binder used in capsule manufacturing. Magnesium Stearate is a lubricant that helps ingredients flow through encapsulation equipment. Silicon Dioxide is an anti-caking agent. These are standard excipients — not active ingredients.

Vitamin B3 (as Niacin) — 20 mg — 125% Daily Value

Niacin is a B-vitamin essential for NAD+ and NADP+ synthesis — coenzymes involved in over 400 enzymatic reactions in the body, including mitochondrial energy production (oxidative phosphorylation) and DNA repair. Every cell in the body requires NAD+ to function.

At 20 mg, Steel Power delivers 125% of the Daily Value. This is a dietary supplement dose, not a therapeutic dose. Niacin at high therapeutic doses (500 mg to 3,000 mg, typically prescribed for lipid management) can cause “niacin flush” — a temporary skin flushing response. At 20 mg, flushing is not expected in most individuals. Men who are sensitive to niacin at any dose should be aware that individual responses vary.

Zinc (as Zinc Oxide) — 11 mg — 100% Daily Value

Zinc is an essential trace mineral. For male reproductive health specifically, zinc has one of the strongest research bases of any micronutrient in this category. Research published in the Journal of Reproduction and Infertility established zinc's essential role in male fertility, sperm quality, and testosterone regulation. A 2020 review in the International Journal of Molecular Sciences further characterized zinc's roles in male fertility and sperm function at the molecular level.

Steel Power uses Zinc Oxide as the zinc source. Zinc Oxide has moderate bioavailability — it is absorbed less efficiently than zinc picolinate or zinc citrate forms used in some other supplements. At 11 mg (100% DV), Steel Power covers baseline zinc needs from the supplement, though men with significant zinc deficiency may benefit from a more bioavailable form at higher doses under clinical guidance.

Important: Do not take Steel Power simultaneously with other zinc-containing supplements unless you track your total daily zinc intake. The Tolerable Upper Intake Level (UL) for zinc is 40 mg per day for adults. Exceeding this regularly can cause copper depletion and gastrointestinal effects. At 11 mg per day from Steel Power, you have significant headroom — but stacking multiple zinc-containing supplements can push you toward or past the UL.

Proprietary Blend — 570 mg total

The proprietary blend contains six ingredients listed in order of predominance by weight. Individual amounts are not disclosed. The total blend is 570 mg per capsule.

L-Citrulline (first in blend — highest amount by weight)

L-Citrulline is an amino acid and the primary nitric oxide precursor in the formula. It converts to L-Arginine in the kidneys, which feeds directly into nitric oxide synthase (NOS) to produce nitric oxide. Nitric oxide signals blood vessel walls to relax, widening the vessel and increasing blood flow. For the full mechanistic explanation of why L-Citrulline is used instead of L-Arginine directly, see the Steel Power ingredients explainer.

Research-validated doses for L-Citrulline in performance and vascular support contexts typically range from 1,500 mg to 3,000 mg per day. The total Steel Power blend is 570 mg across six ingredients. L-Citrulline, as the first-listed ingredient, is present in the highest amount within the blend — but even if it represented 50% of the blend (a favorable assumption), that would be 285 mg. This is below research-validated doses for acute performance effects. Steel Power is positioned as a daily support supplement rather than an acute performance intervention, which is the appropriate framing for this dose level.

L-Carnitine (second in blend)

L-Carnitine is an amino acid derivative that transports long-chain fatty acids into the mitochondrial matrix for beta-oxidation and ATP production. It supports cellular energy metabolism and has published research in the context of sperm motility and male reproductive mitochondrial function. Research doses for L-Carnitine in male fertility contexts typically range from 1,000 mg to 3,000 mg per day — substantially higher than what the proprietary blend structure allows at 570 mg total.

Pine Bark Extract — Pinus pinaster (third in blend)

Pinus pinaster bark extract is a source of oligomeric proanthocyanidins (OPCs) — antioxidant flavonoids that protect the endothelial lining of blood vessels. Research published in the Journal of Sexual Medicine examined the combination of Pinus pinaster extract and L-Arginine supplementation and found that the combination supported erectile function in men by maintaining endothelial integrity. Pine Bark Extract complements L-Citrulline's NO-precursor role by protecting the endothelial cells that produce nitric oxide.

Maca Root Extract — Lepidium meyenii (fourth in blend)

Maca Root is a Peruvian plant used for centuries in traditional medicine for stamina and vitality. Research has primarily examined its effects on libido and sexual desire in men, with several randomized controlled trials showing improvements in self-reported sexual desire compared to placebo. A systematic review in BMC Complementary Medicine found that maca improved sexual dysfunction and sexual desire in both men and women. Maca's mechanism is not fully characterized — it does not appear to work through testosterone elevation or the same NO pathway as L-Citrulline.

Grape Skin Extract — Vitis vinifera (fifth in blend)

Grape Skin Extract is a source of resveratrol and anthocyanins — polyphenol antioxidants with documented roles in cardiovascular and vascular health. Research supports roles in maintaining endothelial function and reducing oxidative stress in blood vessels. In the context of this formula, Grape Skin Extract provides complementary vascular antioxidant support alongside Pine Bark Extract. Note that this ingredient does not appear prominently in the Steel Power marketing copy, despite being on the verified label.

Saffron Extract — Crocus sativus Stigmas (sixth in blend — lowest amount by weight)

Saffron Extract from Crocus sativus stigmas is the final ingredient in the proprietary blend. Published research has examined saffron in the context of male sexual function, with a meta-analysis in Human Psychopharmacology finding that saffron supplementation was associated with improvements in erectile function scores compared to placebo in men experiencing sexual dysfunction. The proposed mechanism involves saffron's effects on serotonin and nitric oxide pathways. Saffron is also one of the more expensive botanical ingredients by weight, which may explain its position as the smallest-quantity ingredient in the blend given the product's price point.

Frequently Asked Questions

Does Steel Power contain Tribulus Terrestris?

Tribulus Terrestris does not appear on the Steel Power Supplement Facts panel. It appears in the website's ingredient description section, but it is not listed as an ingredient in the verified formula. Content on this page is written exclusively to the Supplement Facts panel.

Does Steel Power contain Panax Ginseng?

Panax Ginseng does not appear on the Steel Power Supplement Facts panel. Like Tribulus Terrestris, it appears in some website marketing descriptions but is not listed on the verified label. The six ingredients in the proprietary blend are L-Citrulline, L-Carnitine, Pine Bark Extract, Maca Root Extract, Grape Skin Extract, and Saffron Extract.

What is the total dose of the Steel Power proprietary blend?

The Steel Power proprietary blend totals 570 mg per capsule across six ingredients. Individual amounts within the blend are not disclosed. For context on how this total compares to research-validated doses for individual ingredients, see the Steel Power ingredients explainer.

Is Steel Power gluten-free?

Steel Power uses a hypromellose vegetable capsule and does not list gluten-containing ingredients on its label. The company's website states the formula is non-GMO. Individuals with celiac disease or severe gluten sensitivity should confirm directly with the manufacturer before use.

Steel Power Ingredients and How They Work

by

Disclosure: This article may contain affiliate links. If you click a link and make a purchase, we may receive a commission at no additional cost to you. All opinions remain our own.

Understanding why a supplement might work starts with understanding the mechanism — what happens in the body when you take it. For male performance supplements, the mechanism almost always comes back to blood flow. Nitric oxide is the molecule at the center of that mechanism, and it's the reason ingredients like L-Citrulline and Pine Bark Extract show up in the most studied formulas in this category. This article breaks down how the verified ingredients in Steel Power are designed to work, using exercise physiology and published research — not marketing copy.

Nitric Oxide: The Foundation of the Mechanism

Nitric oxide (NO) is a gas produced naturally in the endothelial cells lining your blood vessels. It signals the smooth muscle in vessel walls to relax, widening the vessel and increasing blood flow — a process called vasodilation. In an exercise context, this is why pre-workout supplements built around NO precursors help with “pump”: more blood flowing to working muscles means more oxygen and nutrient delivery during exercise and faster clearance of metabolic waste products during recovery.

In a male sexual health context, vasodilation is directly relevant to erectile function. The mechanism of erection is fundamentally vascular — it depends on increased blood flow to erectile tissue. This is why PDE5 inhibitors (pharmaceutical medications) work the way they do, and it's also why certain naturally-occurring NO-supporting compounds have attracted research interest as nutritional support for vascular function. Steel Power's formula targets this pathway through two primary ingredients: L-Citrulline and Pine Bark Extract.

L-Citrulline: The Nitric Oxide Precursor

L-Citrulline is an amino acid that converts to L-Arginine in the kidneys. L-Arginine is the direct substrate for nitric oxide synthase (NOS), the enzyme that produces nitric oxide. This pathway is why L-Arginine was historically used in performance and male health supplements — it feeds directly into NO production.

The reason modern formulas use L-Citrulline instead of L-Arginine is bioavailability. When you take L-Arginine orally, a significant portion is broken down in the intestines and liver (first-pass metabolism) before it reaches circulation. L-Citrulline bypasses this degradation pathway. It enters circulation largely intact, converts to L-Arginine in the kidneys, and delivers a more sustained and higher blood concentration of L-Arginine than L-Arginine supplementation itself does at equivalent doses. The result is more sustained NO production compared to direct L-Arginine supplementation.

L-Citrulline is the first-listed ingredient in Steel Power's 570 mg proprietary blend. Because the blend is proprietary, the exact milligram amount of L-Citrulline is not disclosed. Research on L-Citrulline in male performance contexts typically uses doses in the 1,500 mg to 3,000 mg range. The total blend is 570 mg across six ingredients, which means Steel Power is formulated as a daily maintenance-level support supplement — not a high-dose acute intervention comparable to research doses used in clinical trials.

Pine Bark Extract (Pinus pinaster): Vascular Protection and Synergistic NO Support

Pine Bark Extract from Pinus pinaster is a source of oligomeric proanthocyanidins (OPCs), a class of flavonoid antioxidants. Research published in the Journal of Sexual Medicine examined the combination of Pinus pinaster extract and L-Arginine and found that the combination supported erectile function in men through protection of the endothelial lining of blood vessels. Healthy endothelial cells are what produce nitric oxide via NOS — so protecting that lining is as important as providing the substrate for NO synthesis.

This endothelial-protective role is the synergistic value of Pine Bark Extract alongside L-Citrulline. L-Citrulline increases the substrate available for NO production. Pine Bark Extract helps protect the cellular machinery that produces NO. Together, they address the same vasodilation pathway from two complementary angles.

L-Carnitine: Cellular Energy Metabolism

L-Carnitine is an amino acid derivative that plays a specific structural role in energy metabolism: it transports long-chain fatty acids into the mitochondrial matrix, where they undergo beta-oxidation to produce ATP. Without adequate carnitine, fatty acid oxidation is impaired, and the cell's preferred fuel source for sustained activity becomes less accessible.

In a male performance supplement context, L-Carnitine's primary relevance is endurance — it helps the body access fat as fuel during sustained physical or physiological activity. Research has also examined L-Carnitine in the context of sperm motility and male reproductive health, with several studies suggesting that carnitine plays a structural role in the mitochondria of sperm cells, which are heavily dependent on fatty acid oxidation for motility energy.

Maca Root Extract (Lepidium meyenii): Adaptogenic Stamina Support

Maca Root, from the Peruvian plant Lepidium meyenii, is classified as an adaptogen — a compound traditionally used to support the body's resilience under physical and psychological stress. It has been used in traditional Andean medicine for stamina and vitality for centuries. Research in male health has examined maca primarily in the context of libido and sexual function support, with several studies showing improvements in self-reported sexual desire in men taking maca compared to placebo.

Maca does not appear to work through the same nitric oxide pathway as L-Citrulline and Pine Bark Extract. Its mechanism is not fully characterized in the peer-reviewed literature. The most consistent finding across studies is the impact on perceived libido and sexual desire — a psychological and hormonal dimension of male performance separate from the vascular dimension addressed by L-Citrulline.

Grape Skin Extract (Vitis vinifera) and Saffron Extract (Crocus sativus)

Grape Skin Extract from Vitis vinifera is a source of resveratrol and anthocyanins — polyphenol antioxidants with documented roles in cardiovascular and vascular health. Research supports roles in supporting healthy endothelial function and reducing oxidative stress in blood vessels. In the context of Steel Power's nitric oxide-focused formula, Grape Skin Extract contributes additional vascular antioxidant support, complementing Pine Bark Extract's endothelial protective role.

Saffron Extract from Crocus sativus stigmas is the sixth ingredient in the proprietary blend. Research on saffron in male health has focused primarily on its effects on sexual function and mood, with several studies examining its use in men experiencing sexual dysfunction related to antidepressant use. A meta-analysis published in Human Psychopharmacology found that saffron supplementation was associated with improvements in erectile function scores compared to placebo. The proposed mechanism involves saffron's effects on serotonin and nitric oxide pathways.

Zinc and Vitamin B3: The Micronutrient Foundation

Outside the proprietary blend, Steel Power delivers two labeled micronutrients: Zinc as Zinc Oxide at 11 mg (100% Daily Value) and Vitamin B3 as Niacin at 20 mg (125% Daily Value). These are not window-dressing — they address physiological foundations that support the mechanisms above.

Zinc is an essential mineral for testosterone biosynthesis. Research published in the Journal of Reproduction and Infertility and the International Journal of Molecular Sciences established zinc's essential role in male fertility, testosterone regulation, and sperm health. Zinc deficiency is associated with reduced testosterone levels, and supplementation in zinc-deficient men has been shown to restore testosterone toward normal ranges. Steel Power delivers the full Daily Value of zinc in each capsule.

Vitamin B3 (Niacin) supports NAD+ synthesis — a critical coenzyme in mitochondrial energy production and cellular metabolism. Niacin also has a documented pharmacological effect on lipid metabolism and vascular health at therapeutic doses; at the 20 mg dietary supplement dose in Steel Power, the primary role is supporting baseline cellular energy metabolism.

What This Means for Gym-Going Men

If you train regularly, you already understand blood flow in a workout context. The same vasodilation that drives muscle pump during training is the mechanism that Steel Power's core ingredients support in a daily context. The formula is not designed to deliver acute performance enhancement the way a pre-workout dose of citrulline does — it's formulated as a daily support supplement that maintains the physiological environment where these mechanisms can function optimally over time.

The proprietary blend at 570 mg total across six ingredients means that individual ingredient doses are below what research-validated acute doses typically look like. This formula is best understood as daily nutritional support, not a high-dose intervention. That framing is consistent with how the company positions the product: a daily capsule for men who want to support their baseline function as part of an active lifestyle.

Male performance supplements are one of the most crowded categories in the supplement industry, and they're also one of the most poorly reviewed. Most content either cheerleads a product with no label work done or dismisses the entire category with vague skepticism. Neither helps you make a decision. This Steel Power review does something different: it reads the actual Supplement Facts panel, documents what's in the capsule, notes where the website marketing diverges from the verified label, and gives you a clear picture of what the product is and isn't. That's what you need to decide if it fits your goals.

What Is Steel Power?

Steel Power is a once-daily dietary supplement in capsule form, marketed to adult men for support with performance, stamina, and vitality. Each bottle contains 30 capsules — a 30-day supply. The product is distributed by Steel Power out of Aurora, Colorado, and is manufactured in the United States. According to the company's website, the manufacturing facility follows Good Manufacturing Practices (GMP) for dietary supplements.

The supplement is positioned as a natural daily support option rather than an acute or pharmaceutical-style intervention. It does not contain prescription drugs, hormones, or stimulants. There is no autoship program by default — it is sold as a one-time purchase unless the customer opts in at checkout.

The Verified Formula: What the Label Actually Says

This is where most reviews fail. They write to the marketing copy on the brand's website instead of the Supplement Facts panel. Here is what the verified panel lists per one-capsule serving:

Vitamin B3 (as Niacin) — 20 mg (125% DV). Zinc (as Zinc Oxide) — 11 mg (100% DV). Proprietary Blend — 570 mg total: L-Citrulline, L-Carnitine, Pine Bark Extract (Pinus pinaster), Maca Root Extract (Lepidium meyenii), Grape Skin Extract (Vitis vinifera), Saffron Extract (Crocus sativus).

The capsule shell is hypromellose, a plant-based material, making Steel Power suitable for men who avoid gelatin-based supplements. Other ingredients listed are Microcrystalline Cellulose, Magnesium Stearate, and Silicon Dioxide — standard excipients used in capsule manufacturing.

Label versus marketing note: Steel Power's website ingredient descriptions reference Tribulus Terrestris and Panax Ginseng. Neither of these compounds appears on the verified Supplement Facts panel. This review writes to the verified label only. For a full breakdown of every ingredient on the panel and what the research says about each, see the Steel Power label breakdown.

How the Formula Is Designed to Work

The core mechanism in Steel Power's verified formula is nitric oxide support. L-Citrulline, the first listed ingredient in the proprietary blend, is an amino acid that converts to L-Arginine in the kidneys. L-Arginine is a direct precursor to nitric oxide — a signaling molecule that promotes vasodilation, meaning it helps blood vessels relax and widen. Better vasodilation supports blood flow throughout the body, which is relevant to both exercise performance and male sexual function.

Pine Bark Extract (Pinus pinaster) works alongside L-Citrulline in this mechanism. Research published in the Journal of Sexual Medicine found that the combination of Pine Bark Extract and L-Arginine supported erectile function in men by protecting the endothelial lining of blood vessels. Steel Power uses L-Citrulline rather than L-Arginine directly — L-Citrulline has a higher absorption rate because it bypasses first-pass liver metabolism. The vasodilation support mechanism is the same.

Zinc supports testosterone physiology. Published research in the Journal of Reproduction and Infertility established zinc as an essential element for male reproductive health and hormonal balance. Steel Power delivers 11 mg of Zinc as Zinc Oxide, which equals 100% of the Daily Value. Vitamin B3 (Niacin) at 20 mg (125% DV) supports cellular energy metabolism and has documented roles in cardiovascular function.

L-Carnitine, Maca Root Extract, Grape Skin Extract, and Saffron Extract round out the 570 mg proprietary blend. For the complete mechanism breakdown of each ingredient at the individual compound level, see the Steel Power ingredients and blood flow explainer.

Pricing and Packages

Steel Power is sold directly through steelpower.shop in three package configurations. All prices are current as of publication and should be verified at the official website before ordering, as pricing may change.

2 Bottles (60-day supply): $79 per bottle — $158 total. 3 Bottles (90-day supply): $69 per bottle — $207 total. 6 Bottles (180-day supply): $49 per bottle — $294 total.

The 6-bottle package is listed as “most popular” and carries the lowest per-bottle cost. Since the company recommends 30 to 90 days of consistent use before evaluating results, the 3- or 6-bottle package aligns better with a realistic trial period than the single-month option. Shipping is free on 3- and 6-bottle orders.

The Guarantee: Read the Full Terms

Steel Power offers a 60-Day Satisfaction Promise from the original purchase date. The guarantee structure is more complex than the headline suggests, and gym members who've bought supplements before will recognize this pattern. Here is what the policy actually requires:

To request a refund, you must contact customer support within 60 days and receive a Return Merchandise Authorization (RMA) number before shipping anything back. Returns without a valid RMA are not accepted. Once you have the RMA, all bottles — empty, full, or partial — plus any bonus items included with your order must be returned within 7 calendar days of receiving the RMA. You pay return shipping. A return-processing fee of up to 20% of the order value is deducted from approved refunds.

A partial refund with no return required may be offered at the company's discretion. This is worth asking about if you don't want to deal with the return logistics. Contact support via the contact page at steelpower.shop or by SMS at +1 844 460 5163.

The 20% processing fee and return-shipping cost make the guarantee less favorable than competitors offering no-questions-asked returns. This is worth factoring into your decision, particularly on larger bundle orders.

What Steel Power Is and Isn't

Steel Power is a DSHEA-compliant dietary supplement formulated to support nitric oxide production, cellular energy, and male vitality through verified botanical and amino acid ingredients. It is not a pharmaceutical. It does not act like one. Men expecting pharmaceutical-level, acute effects will be disappointed with any supplement in this category — that expectation gap is the source of most negative reviews across the entire male performance supplement market, not anything specific to this product.

What Steel Power offers: a once-daily capsule with a verified formula built around ingredients that have published research at the individual compound level relevant to circulation, energy metabolism, and hormonal support. The proprietary blend structure means individual dosages within the 570 mg blend are not disclosed, which is a limitation for men who want to compare specific ingredient amounts against research-validated doses.

For men over 40 who want a no-stimulant, once-daily support option and are prepared to give it 60 to 90 days of consistent use alongside regular exercise and good nutrition, Steel Power is a reasonable option to evaluate. The refund terms require reading before purchase. The label discrepancy between marketing copy and Supplement Facts is worth knowing before you cite the product's ingredient list to anyone.
