Bigfoot Silva is probably the only name MMA fighter with a legitimate excuse to use TRT. He has acromegaly, a form of gigantism. In his case it's brought on by a cyst on his pituitary gland forcing it to produce excess growth hormone(hence the Easter Island head and giant feet/hands). This totally fucks up how his body produces hormones and in his case makes his testosterone production so low that he supposedly actually lactated at one point. Bigfoot titmilk. Think about that.
So they're finally going to have surgery to remove the cyst, which involves going through his face to get at it. Something he'd not have to do if he could do a proper TRT regimen. But he can't. Because guys like Chael Sonnen use TRT as a loophole to juice.

It sucks for him, but it's such a freak occurrence that it's not like they could rule around him.
I was just talking the other day about how there's no young hyped up HW's in the pipeline. I'm now reminded of when Bigfoot was still just a prospect with the Nogueiras. He went by the nickname "Junior" and he was getting talked about like a mythical animal. I couldn't wait for him to really hit the scene.
And when he finally did with Elite XC it was awesome. He was 265lbs but still somehow explosive. Jumping knees and shit that didn't look awkward, from a 265lb dude! But after a couple fights he kind of slowed down, turns more and more plodding until he got to what he is today. Big hitting grinder with a vicious top game. But the flashy stuff and sneaky athleticism is gone. I wonder how much of that is because of his condition and how much is just age(he's 34 now).
