UFC welterweight Jim Wallhead has accepted a nine-month sanction after testing positive for a prohibited substance stemming from a contaminated supplement. 

USADA sent a press release today announcing the news. 

"Wallhead, 33, tested positive for ostarine and its metabolite following an out-of-competition test conducted on October 7, 2017," the release states. "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 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, which has prompted the U.S. Food and Drug Administration (FDA) to issue warning letters to specific dietary supplement manufacturers stating that ostarine is an unapproved new drug and that selling the drug is in violation of the Federal Food, Drug, and Cosmetic Act. More information about the risks of ostarine can be found through a USADA athlete advisory." 

Tom Lawlor and Tim Means have also been flagged for ostarine in the past, echoing USADA's statements about the prevalence of this illegal substance. 

"Following notification of his positive test, Wallhead provided USADA with information about a dietary supplement product he was using at the time of the relevant sample collection," the release continued. "Although no prohibited substances were listed on the supplement label, testing conducted on an independently sourced, unopened container of the product by the WADA-accredited laboratory in Salt Lake City, Utah, indicated that it 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 High Risk List of supplements maintained on USADA’s online dietary supplement safety education and awareness resource — Supplement 411 (www.Supplement411.org)." 

Because of this, Wallhead was issued a reduced sanction, in this case, nine months. 

"Under the UFC Anti-Doping Policy, as well as the World Anti-Doping Code, a violation caused by a contaminated product may result in a reduced sanction," the USADA release said. "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, depending on the athlete’s degree of fault.

"Here, USADA took into consideration the circumstances that resulted in Wallhead’s positive test, including his failure to thoroughly research the contaminated supplement, or recognize the increased risk of purchasing a supplement from a supplier that also produces products with prohibited substances. As such, USADA determined that a nine-month period of ineligibility was an appropriate sanction under the rules for his violation." 

The period of ineligibility is retroactive to the test date, Oct. 7, 2017, making him eligible to return in July of 2018. 

Wallhead most recently lost to Luan Chagas at UFC 212 in June 2017. He was scheduled to face Warlley Alves Oct. 21 at UFC Fight Night 118 but pulled out of that fight with an injury.
