Brazilian jiu-jitsu /submission grappling is like this right now

The biggest events don't test. That's adcc and ibjjf tournaments only test the winners of black and belt and they can skip the testing somehow

Personally I think it's bad for the sport and hobby. Downstream effects where it normalizes ped use for hobbyist tournaments and delusional parents have their kids on steroids and try. The best don't win neccesarily, just who handles the drugs the best
