Layne won his natty pro card at 5'11 195lbs shredded. Are you saying he's not natural because of his weight alone? That's all you base it off? And Layne and everyone knows his genetics aren't all that great btw... so somebody with awesome genetics and work ethic should be able to surpass that naturally.
People greatly underestimate the natural limit.
I don't even have the greatest bodybuilding genetics in the world, or the best work ethic, but I've still managed to build a physique that garners attention in a short amount of time.
It's a symptom of the laziness that permeates society today; the quickness with which people reach for a needle.
I guess the thought is, "I can't do that, so he must be cheating somehow!."
