Professional grappling is not generally known as a sport with stringent drug-testing, and in fact, the majority of promotions don’t test athletes at all. The IBJJF is the only major organization that does test athletes, and even they only test a small number of those competing. Regardless, they still manage to catch athletes once in a while and Felipe Pena has now failed the second test of his career for PEDs.
Pena first failed a test in 2015 and he has now failed a second test that was conducted during the 2021 IBJJF world championships. Pena won gold in the absolute division and bronze in his weightclass at the event, but will now be stripped of both medals and banned for competition for one year after testing positive for Clomiphene and it’s metabolites, although Pena claims that this was taken at the instruction of his doctor.
