UFC Fighter Amanda Ribas Accepts Two-Year Suspension

USADA announced on Wednesday that UFC athlete Amanda Ribas, of Coconut Creek, Fla., has tested positive for a prohibited substance and accepted a two-year sanction for her anti-doping policy violation.

Ribas (6-1) had been slated to make her UFC debut at The Ultimate Fighter 25 Finale on July 7 against Juliana Lima, but was removed from the fight card after being flagged for a potential anti-doping violation

Ribas, 24, tested positive for ostarine following an out-of-competition urine test conducted on June 7, 2017. Ostarine is a non-Specified Substance in the class of Anabolic Agents and prohibited at all times under the UFC Anti-Doping Policy, which has adopted the World Anti-Doping Agency Prohibited List.

Ostarine, also known as MK-2866 and Enobosarm, is a non-FDA approved selective androgen receptor modulator (SARM) that is illegally sold in the United States and worldwide as a performance-enhancing substance. Ostarine is not currently available as a prescription medication in any country, and its unauthorized use may carry serious side effects. More information about the risks of ostarine can be found through a USADA athlete advisory.

Ribas’ two-year period of ineligibility, the standard sanction for a first offense involving a non-Specified Substance, began on June 7, 2017, the date her positive sample was collected. Ribas’ positive test also falls under the jurisdiction of the Nevada State Athletic Commission, which may impose additional sanctions, including fines or a period of ineligibility that is longer than the period set forth above.
