Federal law has added designer anabolic substances to the anabolic-steroid definition, so a product marketed as a prohormone can fall under it depending on its exact ingredient. As of October 14, 2026, the word prohormone does not answer the legal question; the exact ingredient on the label does. A product can be sold as a supplement, face a state age-sale rule, and still be prohibited in tested sport.
Disclosure: This page is general information, not legal advice.
Are prohormones legal in the United States?
For federal law, start with the ingredient—not the front-label phrase “legal steroid” or “prohormone.” The federal definition of an anabolic steroid includes named substances and certain chemically related substances that promote muscle growth, while also setting out a specific exclusion for dehydroepiandrosterone (DHEA). Read the current statutory definition in 21 U.S.C. 802.
That means DHEA’s federal treatment is not a shortcut for every other hormone-related ingredient. Compare every active ingredient, spelling and chemical name on the current label with the statutory definition. If the ingredient is covered, calling the bottle a supplement does not change that category.
| Question | What answers it | What to check |
|---|---|---|
| Federal status | Federal definition | Exact active ingredient |
| Prescription / controlled-substance status | Federal schedules | Whether the exact substance is an anabolic steroid |
| State sale or delivery rule | Current state statute | Your state, age and transaction |
| Sport eligibility | WADA or NCAA rule | Your sport and governing body |
| Military eligibility | Current service policy | Your branch and duty status |
As of October 14, 2026, federal law lists anabolic steroids in Schedule III. The DEA steroid overview describes anabolic steroids as synthetic variants of testosterone. That is different from a label using testosterone-like marketing.
If your goal is ordinary gym progress rather than a hormone product, start with the basics you can identify on a label. Our creatine guide explains one common performance ingredient without treating it as a steroid.
How do you read a prohormone ingredient list?
Use the complete current label. Do not rely on a product name, a seller category, a social post, or a claim that something is “legal.” Look for the active ingredient list, the form of the product, and the claims used to market it. Then compare the ingredient names with the federal definition.
DHEA deserves its own line on your card. The federal definition excludes DHEA, but California’s current rule separately makes it a misdemeanor to sell, transfer, or furnish a dietary supplement containing DHEA—or specified listed precursors including androstenedione—to a person under 18. The rule is in California Health and Safety Code 110423.2. As of October 14, 2026, that is a California minor-sale rule, not a blanket federal clearance for DHEA or every formula.
California also enacted AB 2030 on September 28, 2026. It is an enacted future rule, not a current rule: under California’s effective-date provision, it takes effect January 1, 2027. The act restricts sales and delivery of covered weight-loss and muscle-building supplements to people under 18, with stated exceptions and delivery-verification options. See AB 2030 and the California effective-date rule.
New York already has a current, separate rule. As of October 14, 2026, its law restricts sales, offers, and promotional giveaways of covered muscle-building supplements to people under 18; covered deliveries require an adult signature and government photo ID. The statute considers ingredients, marketing, and placement, and names steroids and creatine among factors a court may consider. Read New York GBL 391-oo for the exact scope. It is not a possession ban.
“Legal” also does not mean a product is safe or effective. The FDA bodybuilding-product warning says some products marketed as supplements may illegally contain steroids or steroid-like substances and describes serious reported risks. If hormone concerns are part of why you are considering one, use a clinician route rather than trying to solve that question from a supplement label.
Can you use prohormones if you compete?
For sport, assume the answer needs a separate check even if a product is sold openly. The 2026 WADA Prohibited List, effective January 1, 2026, prohibits anabolic agents at all times. Its scope includes anabolic agents and non-approved substances, including designer drugs without current governmental approval for human therapeutic use.
The NCAA banned-substances policy also bans anabolic agents and chemically or pharmacologically related substances. It says there is no complete list, no NCAA-approved nutritional or dietary supplements, and that athletes should have products reviewed with appropriate athletics staff. A bottle’s availability in a store does not answer your eligibility question.

Use this legal category and jurisdiction card
A product can be sold as a supplement, subject to an age restriction, and still be prohibited by a sports organization. Use this card to record what a current official source says about one exact product and one activity. It does not issue legal clearance.
How to use it
- Copy the exact current product name and complete label. Identify Supplement Facts, Drug Facts, or a prescription drug instead of relying on phrases such as “legal steroids.”
- Choose the activity you need answered: sale, delivery, purchase, possession, or sports participation. Record the state and date.
- Read the current official rule and its definition. Check whether the product’s ingredients, format, and marketing fall within that definition.
- Record whether the source is current law, an enacted future rule, a proposal, or an unresolved question. Never treat an introduced bill’s effective-date sentence as enacted law.
- Keep the conclusion narrow. For a personal product or business decision that remains uncertain, use the recorded facts to obtain qualified advice.

Worked example: fictional shopper
Alex, age 28, is comparing a hypothetical creatine powder marketed for muscle strength and delivered to New York on October 9, 2026.
| Exact product, form, flavor and label date | Hypothetical Strength Powder, unflavored powder; illustrative label only |
|---|---|
| Complete ingredients and relevant marketing claims | Creatine monohydrate; hypothetical muscle-strength marketing |
| State / country and action | New York; online purchase and delivery |
| Age context | Adult, 28 |
| Official source and date checked | New York GBL 391-oo; checked October 10, 2026, for the October 9 snapshot |
| Rule status | Current rule; effective April 22, 2024 |
| What the source establishes | Creatine and muscle-building marketing are relevant scope factors. Covered shipments require an adult signature and government photo ID at delivery. |
| What remains product-specific | The card is not a certification that a hypothetical product complies. |
What should you do next?
Take a photo of the full label, fill in one card for the exact product and your exact activity, then read the linked federal, state, or sport rule that answers that activity. If the question is about hormones or a prescription, take the label to a clinician. That gives you a narrower answer than any “legal prohormone” headline can provide.
