I'd bet against it. Maybe in his pre UFC USADA days, but he's the most tested fighter on the roster, works like a mofo and has crazy body awareness and control, and has cardio issues that PEDs could solve. If he's using, he's both very good and very bad at it.
I hope your right, and maybe he doesn't. But to me, this right here looks like classic definition of too much DHT.
