Testosterone replacement therapy is a controversial subject in MMA, but not for Jose Aldo. The UFC’s featherweight champion isn’t against TRT, and he explained the reason.

"I don’t see the problem with using TRT," Aldo told Tatame. "Everybody uses [steroids], from the champion to the newcomer. I believe we [from Nova Uniao] are the only ones that don’t do that, because Andre (Pederneiras) was always against steroids. I think it’s wrong to criticize someone who came forward and said they take TRT."

Aldo won’t point fingers at Vitor Belfort, like many do, for using the testosterone replacement therapy, and he said he doesn’t believe Randy Couture was clean during his 12-year MMA career, despite the fact that "The Natural" never tested positive for any prohibited substance.

"Americans always used that," he said. "Randy Couture fought until he was 50, and you say he was clean? If the doctors prescribe you and you’re on the limits, OK, I see no problem. If I need that one day, I will use TRT too."
