I spotted my buddy (who's lifetime natty) do 225 lbs x 49 reps on the bench. (and 315 x 23).
Was mind-boggling to see. He was totally pissed at not reaching 50 reps w/ it.

He's one of those odd-bodied, barrel-chest, chicken-leg guys. Weighed 270 at the time.
Dude was clueless though, didnt know what "pro-hormones" were, never did gear, etc...
Just benched and did cardio. One of those weird oddities of a person..
