Michael Bisping has had a considerably successful MMA career. He's been one of the better draws in the UFC, in part because he does have the "people who hate him watch to see him get his ass kicked" part of things down to an art form. And, it's worth noting that he's been plenty successful in the cage.
Bisping isn't willing to let people forget that three men he has lost to in high profile bouts have all had serious issues with drug tests this year. There's Wanderlei Silva, who ran from a drug test collector, Vitor Belfort, who tested positive for significantly elevated testosterone levels, and Chael Sonnen, who failed two separate drug tests for seemingly everything under the sun.
Bisping told MMA Junkie that he feels his opponent was on PEDs during every one of those fights, "We all know they weren’t f–king clean. They’ve only just started doing blood tests. People have been taking (human) growth hormone and EPO and all kinds of s–t for years. A urine sample will only show certain things, and people know when to come off stuff. It’s an IQ test. The blood test they do now will catch more people because they’re testing for more things, but they didn’t do that before."
He was especially hard on a fighter he has never faced, Robert Drysdale. Drysdale failed a drug test that he claimed was due to his own round of Testosterone Replacement Therapy, and then went on to claim he didn't need it and then popped for using banned substances.
"F–king Drysdale, he can kiss my ass," Bisping told Junkie. "I’ve never met the guy, he could be the nicest guy in the world, but what I see is a guy who failed his f–king test, then was on TRT, then said, ‘Oh, I don’t need TRT.’ He came off it and there you go, that’s my f–king problem with TRT right from the get-go. You either need TRT or you don’t. You can’t get a doctor to prescribe it and say, ‘Oh, I don’t need it and I’ll come off it.’ You’re a cheat, and now he failed his IQ test. Not only is he a steroid cheat, but he’s f–king stupid."
