the drug use at the top of the IFPA/WNBF is rampant. The Yorton Cup just let a guy who popped for deca in 2002 win his class and I've come across some NPC competitors that help natural pros out with their drug regime in the off season.
Layne is huge in contest shape btw...around 195-200 shredded at 5'10......2+2 here
Whitacre is probably the peak for top natural genes, but who knows he could be using too.
