USADA announced today that Marco Leopoldo Reyes, known professionally as Polo Reyes, of Nayarit, Mexico, has accepted a six-month sanction for a violation of the UFC® Anti-Doping Policy after testing positive for a prohibited substance from a contaminated supplement. 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 <https://www.usada.org/substance-profile-ostarine/>, also known as MK-2866 and Enobosarm, is a selective androgen receptor modulator (SARM) https://www.usada.org/selective-androgen-receptor-modulators-sarms-prohibited-class-anabolic-agencts/ 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 <https://www.usada.org/substances/supplement-411/supplement-411-faqs/#osta>. More information about the risks of ostarine can be found through a USADA athlete advisory <https://ufc.usada.org/athlete-advisory-ostarine-supplements/>.
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.
The presence of an undisclosed prohibited substance in a product is regarded as contamination. Accordingly, the product has since been added to the list of high risk supplements maintained on USADA’s online dietary supplement safety education and awareness resource – Supplement 411 (www.Supplement411.org).
Under the UFC Anti-Doping Policy, as well as the World Anti-Doping Code, the determination that an athlete’s positive test was caused by a contaminated product may result in a reduced sanction. Where contamination is established, the sanction for a doping offense involving a non-Specified Substance ranges from a reprimand and no period of ineligibility, at a minimum, to a two-year period of ineligibility, at a maximum.
Here, USADA took into consideration the circumstances that resulted in Reyes’ positive test, including his failure to thoroughly research the contaminated supplement and supplier. As such, USADA determined that a six-month period of ineligibility was an appropriate sanction under the rules for his violation. Reyes’ six-month period of ineligibility began on March 15, 2018, the date on which he was provisionally suspended from competition.
Pursuant to the UFC Anti-Doping Policy, all UFC athletes serving a period of ineligibility for an anti-doping policy violation are required to continue to make themselves available for testing to receive credit for time completed under their sanction.
USADA conducts the year-round, independent anti-doping program for all UFC athletes. USADA is an independent, non-profit, non-governmental agency whose sole mission is to preserve the integrity of competition, inspire true sport, and protect the rights of clean athletes. In an effort to aid UFC athletes, as well as their support team members, in understanding the rules applicable to them, USADA provides comprehensive instruction on the UFC Anti-Doping Program website (https://UFC.USADA.org) regarding the testing process and prohibited substances, how to obtain permission to use a necessary medication, and the risks and dangers of taking supplements as well as performance-enhancing and recreational drugs. In addition, the agency manages a drug reference hotline, Drug Reference Online (https://UFC.GlobalDRO.com), conducts educational sessions, and proactively distributes a multitude of educational materials, such as the Prohibited List, easy-reference wallet cards, and periodic athlete alerts.
