Ben Rothwell knows a thing or two about performance enhancing drugs.
The UFC heavyweight contender was suspended nine months following his TKO victory over Brandon Vera at UFC 164 due to elevated levels of testosterone. Rothwell was undergoing testosterone replacement therapy (TRT) and had a therapeutic use exemption (TUE) to compete as such, but still tested high.
2-0 since then, Rothwell hasn't shown any ill effects of being off TRT, at least not in the win column. He's just not so sure the rest of the heavyweight division will be as fortunate.
"Before USADA, I would say 80 percent or more heavyweights were on performance-enhancing drugs," Rothwell told ESPN's Brett Okamoto.
