Hearing GH15 talk about Anna 50 during pre-contest, I do believe he's spot on. A friend of mine placed 3rd to Jay Cutler and Branch Warren at an amateur show many many moons ago. This guy was a genetic freak (my friend) and probably could have done some damage in bodybuilding but due to legal troubles and money troubles his dreams were crushed.
But anyway, this guy wasn't quite huge by no means. He had more of one of those Dexter Jackson physiques/genetics. He also didn't have a whole lot of extensive knowledge about aas at the time. But one thing he did say, and this was years later after Cutler became pro. He said, that him and Cutler hung back stage at the show and one of Cutler's main staples for his pre-contest was A-50. Said Cutler loved it!!! I do believe Jay was being advised by Chris Aceto back then, not sure if it was that early though. The contest i'm referring to is the one on youtube were you'll see a young Branch and Cutler competing together or in the same show. That's the one.
