UFC women's strawweight contender Iasmin Lucindo will miss nearly a year of competition after accepting a nine-month anti-doping suspension stemming from a positive test for mesterolone, an anabolic steroid typically used to treat low testosterone. The suspension, announced Wednesday by UFC anti-doping partner Combat Sports Anti-Doping (CSAD), serves as a cautionary tale for fighters navigating the murky waters of supplementation in combat sports. With the suspension retroactive to the sample collection date, Lucindo will be cleared to compete again on June 24, 2026. The investigation concluded that her positive test resulted from a contaminated dietary supplement she obtained from a Brazilian pharmacy known for compounding products containing the banned substance. The contaminated supplement defense has become increasingly common in combat sports, highlighting a persistent vulnerability in how fighters source nutritional products.
