It's around 5 weeks since that episode. My unreliable recollection was that Hackleman was very against TRT - and against his fighters using it - because it effects the natural production: the end result being that there are long-term problems.
However, both he and Rogan were open about how widely it's used and - and this is the haziest part - Hackleman said something pragmatic about what he'd do if one of his guys wanted to use it. Can't remember exactly what.
The gist is, it's commonplace in the UFC because it enables fighters to have longer careers, recover from injuries quicker, train harder... but it's bad for the fighters in the long-term.
PS I agree, that Victor Conte episode was fascinating.
