Former UFC heavyweight champion and WWE superstar Brock Lesnar tested positive for a prohibited substance in a test administered well before UFC 200, but the results did not come back until after the event. The fighter was then suspended.
There were rumors that he had failed for something relatively innocuous, in a prescription inhaler, and that conceivably a retroactive Therapeutic Use Exemption could be applied for.
However, it was next announced that Lesnar had failed another test. And now the highly reliable Lance Pugmire for the LA Times, is reporting what Lesnar allegedly failed for, and it is not an inhaler.
An official with knowledge of Lesnar’s samples identified the banned substance as the fertility drug clomiphene, one of the two banned substances found in a June sample taken from former UFC light-heavyweight champion Jon Jones.
UFC 200 was marred just days before by interim light heavyweight Jon Jones removal from the card, after he failed for letrozole, and like Lesnar, clomiphene.
“They both boost testosterone levels,” explained disgraced PED developer turned anti-PED advocate Victor Conte to Pugmire. “Clomiphene is a PED. It enhances performance. It can increase testosterone by 50%. I personally used it during the BALCO days.
“The [letrozole] blocks conversion of testosterone to estrogen … making you stronger, faster and aiding your recovery [between workouts]. … It’d be like increasing the amount of water going into a bathtub with [clomiphene] and reducing the size of the drain with the [letrozole]. The effect is more water in the bathtub — more testosterone. The drugs are synergistic.”
Conte said he has never heard of either substance showing up in nutritional supplements.
“Either bring in the supplement and have it tested, or that excuse is a smoke screen,” said Conte.
