Anyone know the history of TRT (testosterone replacement therapy) in the UFC before UFC 117? This topic was recently discussed briefly on my show (due to Rothwell), and we decided to look into the history of TRT. We came up short when looking for answers, so I'm turning to you guys. I was also looking into a possible change in testing methods in the UFC around that era, originally because I thought there might be a correlation between HGH testing and the emergence of TRT. However, I was wrong about HGH testing-- the UFC never started testing (the NFL did.) That doesn't mean that there wasn't a change in the athletic commission's methods that would force fighters to change usage, especially the testing of "elevated levels", which is something you hear more about of late. Before, when someone failed, it was for a specific steroid ie. Nandrolone, Masteron, etc. I cannot recall a fighter getting suspended for "elevated levels" until the days of TRT.
