The U.S. Anti-Doping Agency has determined that UFC bantamweight Guangyou Ning is not at fault for a failed out-of-competition drug test earlier this year.
Ning, 34, tested positive for traces of the banned anabolic agent clenbuterol in a urine sample provided on May 19. Clenbuterol is often used to treat breathing disorders and while it has never been approved by the U.S. FDA, it is available in other countries throughout the world. As far as a potential performance enhancer, it is believed to aid fat loss for anabolic steroid users.
However, USADA issued a statement Tuesday clearing Ning of any wrongdoing because his positive test likely resulted from contaminated meat.
“Consistent with numerous prior reported cases globally, the issue of illicit administration of clenbuterol to animals destined for food production can result in, under specific conditions, a positive sample from an athlete. WADA has issued specific warnings about this problem in China and Mexico,” the statement read.”To USADA’s knowledge, due to strict regulatory and meat certification practices, a clenbuterol positive athlete sample has never been reported after consumption of meat produced in the U.S.
“USADA reviewed all of the evidence, including the athlete’s whereabouts, dietary habits, and the laboratory reports demonstrating very low parts per billion concentrations of the prohibited substance in the athlete’s urine sample, and concluded that the presence of clenbuterol in the athlete’s sample very likely resulted from clenbuterol contaminated meat consumed in China. As a result, Guangyou will not face a period of ineligibility for his positive test.”
A native of Cangzhou, China, Ning's scheduled bout against Marlon Vera at UFC 202 on Aug. 20 has been moved to UFC on Fox 21 the following week. The Las Vegas-based promotion released a statement on the decision Tuesday afternoon:
In late July, UFC was made aware of USADA’s investigation into the source of the prohibited substance clenbuterol in an out of competition sample collected from Ning Guangyou. Given it was initially unclear as to the timing of the resolution of the investigation, UFC made the decision to move Guangyou’s scheduled bout against Marlon Vera on August 20, 2016 at UFC 202 to UFC Fight Night: Maia vs. Condit in Vancouver, BC on August 27, 2016.
Ning, a Tiger Muay Thai product, earned victories over Jianping Yang and Royston Wee in his first two Octagon appearances before dropping a split decision against Marco Beltran in his most recent outing at UFC Fight Night in Seoul on Nov. 28.
