28-year old UFC welterweight Carlos Condit is the latest fighter to express concern about the increased presence of testosterone replacement therapy in Mixed Martial Arts. Though completely legal as long as levels are regulated and a doctor has prescribed the treatment, many argue TRT gives athletes an advantage by allowing them to continue training/competing at a high level despite the natural effects of getting older.

Condit spoke about the subject in a recent interview with Gracie Mag where he explained the rationale behind his problem with TRT, especially in the case of fighters who should not necessarily need it based on age.

“I think it’s a slippery slope, you know what I mean? You let guys start using testosterone and it’s – where does it end,” asked Condit rhetorically. “I wonder, especially for younger guys, I know Frank Mir’s a little bit older and of course your testosterone levels kind of dip as you get older, but some of these younger guys…guys maybe in their late twenties and thirties using testosterone replacement therapy…I wonder why is their testosterone low in the first place? And my theory is they may have been using something in the past, because when you use steroids, your body, after you get off has a hard time bringing yourself up to natural levels.”

Mir, who is 33, received an exemption for TRT leading up to his May 26 title-fight with heavyweight king Junior dos Santos.

“I don’t know man. I’m not going to judge anybody, but that’s just, that’s not – I got to where I am without ever using any performance enhancing drugs,” the interim champion continued. “I love MMA because of the purity of the sport and I think it just muddies the water when you start throwing stuff like that in there.”

The “Natural Born Killer” concluded by acknowledging the responsibility to address the matter truly lies with athletic commissions and UFC executives rather than himself, adding, “Personally I have to just continue with what’s worked for me, and that’s just being clean.”
