Sans their drugs, their physiques are no more impressive than anyone else's, including many who come here. I have seen what I believe to be recent footage of Paul Dillet and he is quite average looking.
That alone should put to bed the cries of "genetics freaks" that Weider, et al tend throw around when writing about these "athletes". Perhaps they respond better to the mass quantities of dope they inject/ingest than others, but all in all they really aren't genetically superior to natural bodybuilders (i.e., real physical culturists). Are their muscle insertions lower/longer? Perhaps, but again, take away their dope and they are nothing.
It may well be Mr. Dillet is a fine individual (Craig Titus, not at all), but given the title of this thread I would have to say that without their chemicals messers Dillet, Titus and Prince are less freakzilla and more plain vanilla.
