UFC flyweight competitor Rachael Ostovich has been suspended by the U.S. Anti-Doping Agency following a failed drug test for two different banned substances.

According to USADA officials, Ostovich tested positive for ostarine and GW1516 following an out-of-competition drug test administered on Jan. 3. Both substances are banned at all times for athletes competing in the UFC.

While a one year suspension was initially issued, Ostovich received a four-month reduction in her sentence due to a provisional suspension she faced in 2019 due to an atypical finding that was being investigated by USADA. That investigation did not end with any type of sanction being issued, so USADA offered Ostovich the additional four-month reduction in her new one year sanction.

Following an investigation into her positive drug test, Ostovich identified a supplement that contained the banned substances, which was later confirmed through additional testing.

“Although ostarine and GW1516 were not listed on the supplement label, the analysis revealed that the product contained ostarine and GW1516, the substances for which Ostovich tested positive,” USADA officials said in a statement. “The product label listed another prohibited substance, but Ostovich did not realize at the time that it was prohibited. Consistent with other cases with similar circumstances, USADA determined that a small reduction from the default two-year period of ineligibility was justified.

“Ostovich received an additional reduction to the otherwise applicable period of ineligibility for her Full and Complete Cooperation. Under the revised UFC (Anti-Doping Program) announced on November 25, 2019, a Full and Complete Cooperation reduction may be granted in the event that an athlete demonstrates that they did not intend to enhance their performance and provided full, prompt, and truthful responses and information to all reasonable inquiries and requests for information.”

Ostarine has repeatedly surfaced as the source of positive drug tests in cases involving tainted supplements. Several athletes have received reduced punishments when the substance was found, and one, ex-UFC heavyweight Josh Barnett, managed to avoid a suspension and receive only a verbal warning when a supplement he used was traced to the selective androgen receptor modulators (SARM).

Ostovich’s eight-month suspension is retroactive to Jan. 3. She hasn’t fought since Jan. 2019, when she suffered a submission loss to Paige VanZant.
