UFC lightweight back after 6 month USADA suspension

October 31, 2018 by Jason Cruz Leave a Comment

On Monday, USADA announced that UFC lightweight Polo Reyes has accepted a six-month sanction for violation of the UFC Anti-Doping Policy.

Reyes tested positive for ostarine after an out-of-competition test on March 8, 2018.

Via USADA press release:

Reyes, 33, tested positive for ostarine following an out-of-competition test conducted on March 8, 2018. 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 (WADA) Prohibited List.

Ostarine, also known as MK-2866 and Enobosarm, is a selective androgen receptor modulator (SARM) that is illegally sold 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. Nonetheless, ostarine has been found as a declared and undeclared ingredient in many dietary supplements. More information about the risks of ostarine can be found through a USADA athlete advisory.

Following notification of his positive test, Reyes provided USADA with information about two dietary supplement products he was using at the time of the relevant sample collection. Although no prohibited substances were listed on the supplement labels, testing conducted on independently sourced, unopened containers of the products by the WADA-accredited laboratory in Salt Lake City, Utah, indicated that they contained Ostarine.

Reyes is the first UFC fighter to have his suspension announced after serving it.

Payout Perspective:

Since coming to the UFC in 2015, Reyes has had two Performance of the Nights including his last fight in January 2018 where be beat Matt Frevola via KO/TKO.  Notably, Reyes worked with USADA to determine the cause of his failed test.  With the suspension behind him, Reyes may continue his lightweight career with the company.
