Todd Duffee
Todd Duffee was one of the guys that people would point to when they wanted to mention how rampant steroid use is in the UFC.
In 2010 Duffee managed to convince doctors he needed testosterone replacement therapy at the ripe old age of 25.
Since testing came in Duffee has only fought once, when he got knocked out by Frank Mir in the 1st round. Considering Mir was also fighting for the 1st time without TRT, it was a bad loss for Duffee. He hasn’t fought since.
