Lou Ferrigno was the big dude in the movie Pumping Iron with Arnold. He was the same guy that played the old school hulk tv show, in the green paint and tore jeans. The dude was incredibly huge in his day and I ran into him at the Olympia in a couple of years ago and he is tall and big still, much better shape than Arnold to this day even. SO what kind of juice did he use, a lot of these guys play down their dosages, but those guys never used insulin or HGH like the bodybuilders of today do.
