Yes. DHEA is banned in sport: the 2026 WADA Prohibited List places it among anabolic agents prohibited at all times, and the NCAA lists DHEA as an anabolic agent. You may see it sold as a supplement, but that retail status does not make it eligible for competition.
If your season, scholarship, roster spot, or testing status matters, keep DHEA off your supplement list and check any medication or ingredient before you use it.
Short answer: is DHEA banned for athletes?
As of October 14, 2026, WADA’s 2026 Prohibited List identifies DHEA under S1 anabolic agents, which are prohibited at all times. That means the restriction is not limited to competition day.
As of October 14, 2026, the NCAA banned-substances guidance also names DHEA in its anabolic-agent examples. The NCAA says its examples are not a complete list and that chemically or pharmacologically related substances can also fall within a banned class.
| Question | Answer as of October 14, 2026 | Source that answers it |
|---|---|---|
| Is DHEA allowed under WADA? | No. It is prohibited at all times as an anabolic agent. | 2026 WADA Prohibited List |
| Is DHEA allowed for NCAA athletes? | No. The NCAA lists it as an anabolic-agent example. | NCAA banned-substances guidance |
| Can it be sold as a supplement? | It is available over the counter as a supplement. | WebMD DHEA overview |
| Can a California minor buy it? | No. California law specifically restricts sale, transfer, or furnishing of DHEA supplements to people under 18. | California Health and Safety Code |
MK-677 is a separate ingredient, but it is also a problem for NCAA athletes: the NCAA places ibutamoren (MK-677) among peptide hormones, growth factors, related substances, and mimetics. Do not assume a product is acceptable because its label uses a different hormone-related name.
Why legal to buy is not legal to compete
These are different rulebooks. The retail question is about whether a product is sold to consumers. The sport question is whether an athlete may have an ingredient in their system under the rules of their competition.
For the federal retail-status question, WebMD’s DHEA overview says DHEA is available over the counter as a dietary supplement and notes that the FDA has not reviewed DHEA for safety and effectiveness. The same page says a prescription DHEA product used vaginally is also available. Neither point changes the WADA or NCAA prohibition for DHEA in sport.
For the prescription question, a medication can have its own status and still require sport-specific review. WADA directs athletes to check medications, while USADA explains that Global DRO can be used for brand-name medications and active ingredients in several countries, including the United States. Global DRO does not cover dietary supplements.
For the military question, use your service’s current policy and chain of command before taking a hormone-related product. Military rules are not answered by WADA, NCAA, California retail law, or an over-the-counter listing.
DHEA is sometimes described as a steroid precursor because the body can convert it into other hormones. A randomized, double-blind, placebo-controlled study described by NutraIngredients enrolled 12 healthy men aged 18 to 42 and compared 50 mg DHEA, 200 mg DHEA, and placebo daily for six months. It reported higher circulating DHEA, DHEA sulfate, and ADG, while testosterone did not significantly rise. That is useful context for a performance claim, but the sport rule is simpler: DHEA is prohibited.

What California’s rule means for minors
As of October 14, 2026, California Health and Safety Code section 110423.2 makes it a misdemeanor for a manufacturer, wholesaler, retailer, or other person to sell, transfer, or furnish a dietary supplement containing DHEA to someone under 18. The statute also requires a seller to request valid identification when a buyer reasonably appears to be under 18.
California has another enacted measure worth keeping separate. AB 2030, Chapter 720, was approved on September 28, 2026. It concerns certain over-the-counter diet pills and supplements marketed for weight loss or muscle building for people under 18. Under California’s general effective-date rule, it takes effect January 1, 2027; it is an enacted future rule, not a current October 14, 2026 rule. It does not replace the existing DHEA-specific restriction in section 110423.2.
That California rule answers a state minor-sale question. It does not decide whether DHEA is permitted by your sport, whether a product is appropriate for you, or whether another state has the same rule.
Check before you take it
Start with the exact ingredient panel. Look for “dehydroepiandrosterone” and “DHEA,” and do not assume a testosterone-booster label makes an ingredient acceptable for sport. NCAA guidance says student-athletes should check with designated athletics staff before using any substance and says there are no NCAA-approved supplements.
A 2026 systematic review of undeclared prohibited substances addresses the prevalence, detection, and sport risks of pharmacological adulterants in dietary supplements. For medications, search the exact active ingredient in Global DRO. For supplements, use a certification database to verify the exact product and lot rather than relying on a logo. USADA says NSF Certified for Sport can reduce, but does not eliminate, the risk of a positive test or sanction. Our sport certification guide explains what NSF Certified for Sport and Informed Sport checks can and cannot tell you.
| Before you take a hormone-related product | Small next step |
|---|---|
| You compete under WADA rules | Check the current Prohibited List and ask your anti-doping organization about the exact substance. |
| You are an NCAA athlete | Bring the exact label to your athletics health staff or use Drug Free Sport AXIS through your school. |
| You are considering a medication | Search its active ingredient in Global DRO and discuss it with the clinician who prescribed it. |
| You are buying a supplement | Verify the exact product and lot in the certifier’s database; certification lowers risk but does not guarantee eligibility. |
| You are under 18 in California | Know that DHEA has a current, ingredient-specific minor-sale restriction. |
WebMD lists acne, increased hair growth, and sexual problems among common DHEA side effects, and advises discussing health conditions and medicines with a health care provider. If liver concerns, fertility, hormone symptoms, or another health concern is part of your decision, bring the exact product label to a clinician rather than guessing from a marketing claim.
This is general information, not legal advice. For an athlete, the clear next step is to check the exact ingredient and product with the organization that governs your competition before you take it.
