The only guy I've seen bench over 500 in a gym (as opposed to a MEET) was an ex-powerlifter (he wasn't "ex" at the time) in New York state. He warmed up with 135, 225, 315, 405, then slapped 505 on the bar and put that shit up like it was nothing. He wasn't juicing at the time that I know of, and the lift was done raw. Of course, he's like 5'4" with arms that are about 10 inches long and had a huge barrel chest, so he was built to bench. Lucky fucker.
