I remember a few years ago, someone I know from the boards said that Jeff "Box" Long heard Ronnie Coleman was doing 30iu's/day. Everyone was freaking out, and this was when Ronnie's gut really started to explode- had everyone thinking it was an insane dosage.
There was a guy over at Muscle Mayhem, aptly named "InsulinShock," who was quite the lunatic. Begging people via the net for $$$ saying he needed bail. I can't remember all the crazy shit the guy rattled off on a post per post basis. The one I DO remember, was he said he claimed to "have broken the 100iu postworkout insulin barrier." Many many people were calling him stupid, rightfully so.
