Sean O’Malley, Nicco Montano, Augusto Mendes, and Marvin Vettori have all been suspended by USADA for having trace amounts of ostarine in their system. USADA was able to prove that there was “no evidence of intentional use” of the substance and the failed tests were caused by contaminated supplements. All four fighters have been retroactively suspended.

O’Malley publicly announced the news of his positive test last September, while the Mendes failure was told to the public by USADA prior to their policy change. They can both return to competition immediately (although Mendes is no longer on the UFC roster). Vettori is eligible to return immediately as well.

Former flyweight champion Montano’s suspension is retroactive to November 15, 2018 meaning she can return to the Octagon on May 15.

Intentional use of ostarine warrants a two-year suspension by USADA and is illegal in the United States.
