On April 30, 2025, the U.S. Anti-Doping Agency (USADA) announced that Professional Fighters League women’s flyweight contender Taila Santos has been handed a six-month suspension after testing positive for multiple banned substances in an out-of-competition sample collected on March 21. The substances detected were oxandrolone and its metabolites, as well as clenbuterol, both classified as anabolic agents and strictly prohibited at all times under the PFL’s anti-doping policy.
