Are GLP-1s Banned in Sports? The 2027 WADA List, USADA and Federations
No. As of October 2026, semaglutide and tirzepatide are not prohibited in WADA-code sport, and they stay off the banned list for 2027. They are on WADA's Monitoring Program, which means testing labs track them without sanctioning anyone. The real anti-doping risk for a tested lifter, grappler, triathlete or college athlete is not a legitimate prescription. It is a grey-market "research" vial that may not contain what the label says.
Key takeaways
- WADA's 2027 Prohibited List, approved in September 2026 and effective January 1, 2027, leaves GLP-1 status unchanged pending more data on their effects in athletes.
- USADA says GLP-1s are not prohibited and no therapeutic use exemption (TUE) is needed today.
- "Monitored" is not "banned," but WADA's science director has noted that monitored substances have often been prohibited later.
- The NCAA's 2026-27 list doesn't name GLP-1s, but it bans anything "chemically/pharmacologically related" to its classes, so college athletes should clear any prescription with team medical staff.
- Unapproved "research use only" GLP-1 products are the biggest practical risk: unknown contents, and under anti-doping rules you own whatever ends up in your sample.
Where GLP-1s stand on the 2027 WADA list
WADA's Executive Committee approved the 2027 List of Prohibited Substances and Methods in September 2026, and it takes effect on January 1, 2027, according to World Triathlon's summary of the update. The headline changes involve cannabinoid wording, glucocorticoid routes, beta-blocker sport listings and clarifying examples in several classes.
GLP-1 receptor agonists were discussed but not added. World Triathlon reports that the status of semaglutide and tirzepatide will remain unchanged for 2027 "pending further data becoming available on the possible effects on athletes who take them", and that WADA's List Expert Advisory Group reviewed the published science before deciding.
That matches what USADA tells athletes. Its April 2026 guide, Weight Loss Drugs: What athletes need to know about GLP-1s, says plainly that GLP-1s are not prohibited in sport and that "you do not need a TUE for any GLP-1."
What "monitored, not prohibited" actually means
WADA runs a Monitoring Program alongside the Prohibited List. Substances on it are tracked in urine samples so WADA can see how often athletes use them and in which sports. A monitored substance in your sample is not an anti-doping rule violation.
WADA's 2026 Monitoring Program lists "Markers of Semaglutide and Tirzepatide" for tracking both in and out of competition.
Monitoring is often a step toward a decision. Adding a substance to the list requires meeting at least two of three criteria: performance enhancement, risk to athlete health, and violation of the spirit of sport. In a July 2026 report, WADA Science Director Olivier Rabin noted that monitored substances have often been prohibited later, and flagged interest in combinations that pair GLP-1s with myostatin inhibitors to limit muscle loss. Other WADA advisers remain unconvinced the drugs give a meaningful competitive edge.
The practical read for a competitor: today, a prescribed GLP-1 is allowed. Each September, when WADA publishes the next year's list, check again.
How the main federations and the NCAA treat GLP-1s
Most US anti-doping programs either adopt the WADA list directly or run their own list modeled on it. Here is where the bodies men ask about most stood as of October 2026.
| Organization | Whose rules | GLP-1 status (Oct 2026) | What to do |
|---|---|---|---|
| USADA (Olympic and Paralympic sports) | WADA Code and list | Not prohibited; no TUE needed | Check products on Global DRO or the USADA Drug Reference Line |
| IBJJF | Follows the WADA Code and list; USADA runs testing | Not prohibited (follows WADA) | Same as USADA; keep prescription records |
| World Triathlon | WADA Code and list | Status unchanged for 2027 | Review the 2027 list before January 1 |
| USA Powerlifting | Its own anti-doping rules and posted prohibited list | Not named on its anti-doping page | Check USAPL's current list; declare prescriptions as its rules require |
| NCAA | Its own banned drug classes (2026-27) | Not named, but "related" substances are banned | Clear it with your athletic trainer or team physician first |

Brazilian jiu-jitsu
The IBJJF says it abides by the World Anti-Doping Code and WADA Prohibited List even though it is not itself a Code signatory, and that USADA handles sample collection, analysis and results management at its tested events. So whatever WADA decides about GLP-1s flows straight through to IBJJF competitors.
Powerlifting
USA Powerlifting's anti-doping page says athletes can be tested year-round without notice and must declare and file a TUE for any banned substance used for a medical condition. It links to its own current prohibited list rather than naming WADA's. One line matters for men over 40: USAPL says no TUEs will be approved "for functional disorders, such as low testosterone or aging." If you are on testosterone alongside a GLP-1, the GLP-1 is not your problem in a tested federation. The testosterone is.
Other lifting federations each publish their own rules. If you compete in more than one, check each one's list rather than assuming they match.
Triathlon and endurance events
World Triathlon follows the WADA list and urged athletes to review the 2027 version as soon as possible. Privately run age-group series set their own anti-doping rules, so read the athlete guide for the specific race series you enter.
NCAA athletes
The NCAA's 2026-27 banned drug classes include peptide hormones and "hormone and metabolic modulators," and neither class lists GLP-1s among its examples. But the NCAA states that "any substance chemically/pharmacologically related to these classes is also banned" and that "there is no complete list of banned substances." A college athlete with a legitimate prescription should get a written answer from team medical staff before the first dose, not after a test.
Compare available care options
If you have a qualifying diagnosis, a licensed prescriber can review whether an FDA-approved GLP-1 fits you; a consult is not a prescription guarantee.

If GLP-1s are added later: how a TUE would work
Nothing requires a TUE today. But if WADA moves a GLP-1 onto the list in a future year, the TUE system is how a man with a real diagnosis would keep competing. USADA's TUE page lays out the three tests its medical committee applies:
- A confirmed diagnosis that requires treatment with the prohibited medication.
- No potential for enhanced performance beyond returning the athlete to a normal state of health.
- No permitted alternative that would appropriately treat the condition.
Applications without medical documentation are returned. That means the paper trail matters: a diagnosis such as type 2 diabetes, obesity, or obstructive sleep apnea, documented by a clinician who examined you, is a very different file from a cash-pay prescription written to help you make weight.
Timing rules differ by athlete level. USADA says athletes in its testing pools must get a TUE before using a prohibited substance, while athletes who are not international- or national-level may be able to apply retroactively. USADA's page doesn't spell out how this applies to every masters category, so confirm your own status with its TUE team before you rely on a retroactive exemption.
The real risk: grey-market and "research" GLP-1s
Most tested athletes who get into trouble with a weight-loss drug won't do it with a pharmacy-filled Zepbound pen. The exposure comes from products bought online without a prescription.
FDA's page on unapproved GLP-1 drugs, updated October 1, 2026, says it has warned companies selling semaglutide, tirzepatide, retatrutide, survodutide and mazdutide labeled "for research purposes" or "not for human consumption" while marketing them for human use with dosing instructions. FDA says the quality of these products is unknown. It also reports counterfeit Ozempic in the US supply that may contain the wrong ingredient, too much, too little, or none.
For an athlete, unknown contents create a second problem on top of the health risk. USADA's guide lists red flags, including products sold without a prescription, claims of "generic" Ozempic or Wegovy, patches, gummies and "research only" labels, and notes there are currently no legal generic versions. USADA's supplement guide adds the principle that decides cases: "Athletes are responsible for everything that goes in and on their body."
Peptide stacks raise the stakes further. The NCAA's banned list names BPC-157 and TB-500 as examples in its peptide hormone class. A "recovery stack" ordered with a research GLP-1 can carry a clear violation even while the GLP-1 itself is permitted.
Performance and health questions tested athletes should ask
Federation medical commissions are less worried about GLP-1s as a doping edge than about what they do to athletes who use them to cut. World Climbing's athlete-health guidance warns that performance-driven use can cause loss of lean muscle mass, impaired strength and inadequate energy availability, raising the risk of Relative Energy Deficiency in Sport. It "strongly advises against off-label use."
For a man with a medical reason to take one, the questions to bring to the prescriber are practical:
- How will we protect strength and lean mass while I'm losing weight, and how will we measure it?
- What happens to my fueling around training and meets when appetite is suppressed?
- Should dose increases avoid my competition calendar, given early GI side effects?
- Can you document my diagnosis clearly in case a TUE is ever needed?
A simple compliance checklist
- Know your rulebook. Identify whether your federation uses the WADA list or its own, and bookmark the current version.
- Check the exact product. Global DRO, run by USADA, UK Anti-Doping, Sport Integrity Canada and Swiss Sport Integrity, lets you look up medications sold in the US against the WADA list. It does not cover supplements. USADA's Drug Reference Line is drugreference@USADA.org or (719) 785-2000, option 2.
- Keep records. Prescription, diagnosis, pharmacy fills and lot numbers.
- Declare when asked. If a doping control form or federation rule asks for current medications, list it.
- Recheck every fall. WADA publishes the next year's list each autumn; the 2027 list takes effect January 1, 2027.
Where this guide stops
This article explains anti-doping status as published by WADA-affiliated bodies and the NCAA as of October 2026. It is not a ruling on your eligibility. Federations can change their rules mid-season, and only your federation, USADA or your school's compliance office can give you an answer that counts. Whether a GLP-1 is medically right for you is a question for a clinician who knows your history.

Frequently asked questions
Is semaglutide or tirzepatide banned by WADA?
No. As of October 2026 neither is on the Prohibited List, and the 2027 list that takes effect January 1, 2027 leaves their status unchanged. Both are on WADA's Monitoring Program, which tracks use without sanctions.
Do I need a TUE for Ozempic, Wegovy, Mounjaro or Zepbound?
Not currently. USADA says GLP-1s are not prohibited in sport, so no therapeutic use exemption is needed. That could change if WADA adds them to a future list.
Are GLP-1s on the NCAA banned drug list?
The NCAA's 2026-27 banned classes don't name GLP-1s, but the NCAA bans any substance chemically or pharmacologically related to its classes and says there is no complete list. College athletes should clear any prescription with team medical staff first.
Can a research peptide GLP-1 cause a positive test?
It can. FDA says the quality of products labeled for research use is unknown, and under anti-doping rules athletes are responsible for everything in their sample, including undeclared ingredients.
Does USA Powerlifting allow TUEs for testosterone?
USA Powerlifting's anti-doping page says it will not approve TUEs for functional disorders such as low testosterone or aging, so testosterone is a bigger issue than a GLP-1 in that federation.
