Ostarine has again popped up as the culprit in contaminated supplement cases involving UFC fighters, with four fighters accepting six-month suspensions, per the promotion’s anti-doping administrator. The U.S. Anti-Doping Agency (USADA) today announced settlements after out-of-competition test failures from Augusto Mendes (March 7, 2018), Marvin Vettori (August 24, 2018), Sean O’Malley (September 5 and December 8, 2018) and inaugural flyweight champ Nicco Montano (October 25, 2018). All but one – Montano – is eligible to compete with their six-month terms retroactive to the date of their provisional suspensions. Both O’Malley and Vettori took to social media to share their reactions.
