Ribas will have to wait a while before making her Octagon
USADA announced Wednesday that the 24-year-old Brazilian has
accepted a two-year suspension after testing positive for ostarine
in an out-of-competition urine test conducted on June 7, 2017.
Ostarine is listed as an anabolic agent and is banned at all times
per the UFC’s Anti-Doping Policy.
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,” the USADA statement read.
“Ostarine is not currently available as a prescription medication
in any country, and its unauthorized use may carry serious side
Ribas’ sanction began on the date her positive sample was
collected, meaning she won’t be eligible to return to active
competition until June 2019. Ribas was scheduled to face Juliana
Lima at “The Ultimate Fighter 25” finale on July 7 before being
provisionally suspended. Ribas has compiled a 6-1 career mark while
competing on the regional circuit in Brazil.
