The thing is , it ' s not only giants like Lesnar and Overeem . Anderson fucking Silva , skinny for a fighter technical master of striking , tested positive . The Chris has had suspicious blood tests . Cormier , who has the opposite build of Brock Lesnar , had suspicious blood tests . Stricter drug testing just favors richer fighters , it ' s more expensive to dodge tests than it is to take PEDs . People exist by consuming chemicals . I have no problem with them consuming better chemicals . Other mainstream sports organizations see The NFL do the same type of halfassed testing that the UFC used to do and it doesn ' t seem to hurt them . Removing title fights see Jon Jones due to failed drug tests does not help mainstream adoption of the sport .
