If you mostly want strength and muscle from your lifting, plain creatine monohydrate is the simpler buy: one ingredient, 5 g per scoop, and a price you can work out per serving. Creatine HMB fits if you want HMB and electrolytes in the same tub, but the two HMB trials in the evidence enroll people with Down syndrome or Huntington's disease, not healthy lifters, so they can't tell you how the blend performs in your training. Below is what each product lists, what each costs per serving, and what to settle before you order.

What is creatine, and what is HMB?
Creatine HMB's page, captured October 25, 2026, describes creatine as “a natural substance your body makes and stores for energy.” Oath Nutrition's listing, captured October 24, 2026, calls it “a compound synthesized from three amino acids to support ATP (energy) production in muscles and brain tissue.” Creatine monohydrate is the plain form, and both pages use that name.
HMB is short for beta-hydroxy-beta-methylbutyrate, the name the ClinicalTrials.gov listings use. Creatine HMB's page says HMB “supports muscle recovery, and works with creatine to build more lean muscle.”
How do the two compare side by side?
Here is what each product's own page or label says.
| Point | Creatine HMB (page captured October 25, 2026) | Oath Nutrition Micronized Creatine Monohydrate (listing captured October 24, 2026) |
|---|---|---|
| What the maker says it is | Creatine, HMB and electrolytes; its page says “The best formulas combine all three.” | Creatine monohydrate alone, “Ultra Micronized for fast mixing and absorption,” unflavored. |
| Creatine per serving | Its page sets a base dose of 5 g a day. | 5 g per 1 scoop, per the label. |
| Other ingredients | Electrolytes are named on its page as part of the best formulas. Amounts are on the label. | “Other Ingredients: None,” per the label. |
| Caffeine | Its page says “No drugs, no stimulants.” | The Supplement Facts list only creatine monohydrate. |
| Directions | “Five grams a day covers most people. More is optional.” | “Mix 1 scoop with 8 fl. ounces of water or beverage of your choice. For optimal results, consume daily.” |
| Main claims | Muscle and strength, memory and focus, and HMB for recovery. | Lean muscle and strength, and, per its listing, a sharper brain. |
| Price per serving | Check the order page for current pricing. | About $0.38 per serving at the sale price (see the price section). |
Who does each one suit?
Creatine HMB suits you if you want the blend its page describes, creatine with HMB and electrolytes, and you're ready to check its price, label and refund terms directly before you buy.
Oath's monohydrate suits you if you want one ingredient, 5 g per scoop, unflavored, with a listed price per serving. To go deeper on plain creatine, read creatine monohydrate. For the micronized form, see micronized creatine vs monohydrate. If you want to weigh blends more broadly, read creatine blends vs monohydrate.
How much does each one cost per serving?
Oath's listing showed these prices on October 24, 2026, for its 50-serving tub:
- One-time purchase: regular price $24.99, sale price $18.75. That works out to about $0.50 and about $0.38 per serving.
- Subscribe and save: the listing says “SAVE 10% OFF THE ONE-TIME PURCHASE PRICE” at $16.88. That is about $0.34 per serving.
- Target rebate: the listing and its FAQ mention $5 off the Creatine 50 serve tub at Target through the Aisle app. It is limited to the first 6,000 customers, receipts must be submitted within 21 days, and “Reimbursement does not include shipping or taxes.”
Oath's label directs one scoop, consumed daily, so the per-serving price is your per-day price. For Creatine HMB, check the order page for current pricing, then divide the bottle price by its serving count to compare. Prices change, so check the checkout for today's figures on both products.
How much should you take, and when?
Creatine HMB's page says five grams a day “covers most people,” and it calls 5 g the starting point. It lists 10 g “for the brain” and 20 g for short-term use as optional. For Oath's monohydrate, the label says one 5 g scoop mixed into 8 fl. ounces of water or your drink, consumed daily.
Can you take HMB and creatine together?
Creatine HMB sells the two as one approach and says they “work better together.” The ClinicalTrials.gov listing NCT07902206 tests creatine, HMB and the combination, and says it will test “whether combined CRE+HMB produces synergistic improvements.” That study enrolls people with Huntington's disease, not healthy lifters.
What do the HMB trials show?
A registration describes a study; it is not a result. Two registered trials in the evidence test creatine and HMB.
- ClinicalTrials.gov study NCT07213063 enrolls people with Down syndrome who can perform basic physical tasks. Participants take creatine (3 g a day) and HMB (3 g a day), or placebo, for 8 weeks. The outcomes measured include muscle strength, balance, cognitive function, body composition and blood markers of health. The listing shows 32 participants planned or enrolled and a status of completed.
- ClinicalTrials.gov study NCT07902206 enrolls adults with Huntington's disease and physical frailty or sarcopenia. All participants follow a 12-week home-based exercise program and are randomized 1:1:1:1 to placebo, creatine, HMB or combined creatine and HMB. Planned outcomes include functional capacity, neuromuscular performance, body composition, cognition and quality of life. The listing plans 88 participants and is not yet recruiting.
Both trials enroll people with specific health conditions, so they are a poor guide to how a blend performs for a healthy lifter.
Is creatine HMB better than regular creatine?
Creatine HMB's page says creatine monohydrate is “the form proven in nearly every study.” Oath's listing says creatine “has more clinically-backed evidence than any other supplement on the planet.” Those are each seller's own words, so check them against the studies themselves before you decide.
Are there side effects, and who should ask a clinician first?
Oath's label warns: “Not intended for persons under the age of 18. Do not use if pregnant or nursing. Consult a healthcare professional if you are taking prescription medications or have any pre-existing medical conditions.” Those warnings are on Oath's product.
Cleveland Clinic's page lists the headline line “Despite rumors, science hasn't shown that creatine causes hair loss.” That is a headline blurb about creatine in general, not about the HMB blend. You can read the Cleveland Clinic hair loss page for its headline wording.
If you take prescription medicine or have a health condition, ask a pharmacist before you start either product.
What about bloating, weight gain, headaches or testosterone?
Creatine HMB's page says creatine “pulls water into your muscles,” which is the seller's own description of how creatine works. It is not a finding about bloating or weight. If bloating, weight gain, headaches, testosterone or fasting is on your mind, bring it to a pharmacist or clinician before you start.
Does creatine HMB have caffeine, and does it taste bad?
Creatine HMB's page says “No drugs, no stimulants.” Oath's Supplement Facts list only creatine monohydrate at 5 g per scoop, with “Other Ingredients: None.”
Oath's listing says “Absolutely no grit or nasty aftertaste,” and one buyer wrote, “Tasteless and that is a good thing.” For the HMB blend's taste and smell, ask Creatine HMB before you buy.
What do buyers say?
Oath's listing shows a rating of 4.84 out of 5 from 55 reviews, captured October 24, 2026. One reviewer wrote that they never ordered the product, and Oath replied asking them to contact customer service. For reviews of the HMB blend, check its sales page and any retailer listing before you buy.
What are the refund, guarantee and shipping terms?
Oath's footer links a Satisfaction Guarantee page and a Return Policy page. Its FAQ answers “Does Oath have a satisfaction guarantee?”, “When can I expect my order?” and “How do I update or cancel my subscription?” Read those answers before you subscribe. Customer service is at (385) 557-6602, Monday to Friday, 9:00am to 5:00pm MST.
Check each seller's order page for refund, guarantee and shipping terms before you pay.
