Realistically, all boxers/athletes use PE's. The difference now is that guys who would have been finished in their mid-30's can reverse the ageing process with HGH and extend their careers. Before you start flaming me for falsely accusing these guys, consider the following: RJJ tested positive in the Hall fight (as did Hall) Toney tested positive in the Ruiz fight and was stripped Vargas tested postive against DLH Mosely's links to Balco Salido tested postivie against Guerrero There are many others. Think of the money involved in boxing. Do you honestly think that for a few million, let alone the ego and vanity of competing at an advanced age, these guys aren't juicing? My argument isn't that boxers use steroids or PE's, but that older boxers are getting a longer shelf life due to HGH specifically.
