WADA Position and Monitoring Lists for Weight-Loss Drugs
The World Anti-Doping Agency continues to evaluate the potential of GLP-1 receptor agonists for athletic enhancement and the associated risks of misuse in sports, according to agency updates. Medications like “Ozempic” and “Mounjaro” have gained widespread popularity far beyond elite athletics. Semaglutide, marketed under the names “Ozempic” and “Wegovy,” first entered the WADA monitoring list in 2024, followed by tirzepatide, known as “Mounjaro,” which joined the monitoring list this year. Rules take effect in January and undergo annual reviews.
Criteria for Banning Substances in Competitive Sports
To move a substance from the monitoring list to the prohibited list, WADA requires it to fulfill at least two out of three specific criteria. According to agency guidelines, the substance must be proven to enhance sports performance, pose a health risk to the athlete, or violate the spirit of sport. WADA has launched one study and is currently preparing a second to analyze the effects of these medications under simulated high-intensity physical exertion conditions.
Medical Warnings and Elite Athlete Usage
Professor Olivier Rabin, senior director of WADA’s science and medicine department, issued a direct warning to athletes regarding the casual use of these drugs. “Never do it without a doctor’s recommendation and supervision. These are drastic changes in the body, and they can have serious side effects and risks – especially for athletes,” Rabin stated in an interview with the BBC. Public admissions have further fueled the debate; U.S. tennis star Serena Williams revealed last year that she utilized weight-loss medication during a career break dedicated to growing her family.
Broader Health Impacts and Secondary Effects
Beyond athletic regulation, researchers are examining how GLP-1 medications influence habits outside of weight control.
