Former UFC heavyweight champion, Brock Lesnar, has received a one year suspension after testing positive for the banned substance clomiphene in an out-of-competition drug test around the time of UFC 200.
Clomiphene is also one of the substances Jon Jones tested positive for around the same time. It’s a prescription medication usually given to women having trouble conceiving, but in recent years has become popular as an alternative to TRT for men with low testosterone, as it can double natural testosterone levels.
Despite clomiphene’s ability to increase testosterone, clomiphene is not classed as an anabolic agent. As a result of its classification as an anti-estrogenic substance it carries the lower one year suspension, instead of the longer two year suspension for other substances.
Lesnar’s representatives claimed at the time that his use was accidental and had eye medication and foot cream tested for traces of clomiphene. It seems he was unable to prove this, as he received the full 12 month suspension.
The suspension comes on the heels of criticism of the UFC’s anti-doping policies regarding substance classification. Controversially, Lyoto Machida was suspended for 18 months for admitting to taking a substance which cannot increase muscle mass, while other athletes like Lesnar received 12 month suspensions for taking substances which double testosterone levels.
The UFC’s anti-doping policy prevents athletes from challenging the classification of a substance on the list, regardless of what evidence they may have that the classification is incorrect.
Brock Lesnar has shown little interest in competing in MMA since his failed test at UFC 200, and is currently one of the WWE’s biggest stars. He is expected to have a feature slot in the WWE’s biggest PPV of the year, Wrestlemania.
