TRT usage didn’t help Vitor Belfort knockout Luke Rockhold and Michael Bisping

UFC middleweight Vitor Belfort knocked out former Strikeforce middleweight champion Luke Rockhold on Saturday night in the UFC on FX 8 main event. Belfort also knocked out Michael Bisping in the main event of the UFC on FX 7 card via second round KO. Both Rockhold and Bisping are thought to be top flight middleweight fighters, yet Belfort blew through both of them with relative ease.
