Height: 5'10
6 1/2 years of natural training maxed out. Genetic limit sucked
You look awesome, dude. But if by "genetic limit sucked" you mean as a nattie, I wouldn't even go that far. You looked very good before, just needed a little more mass. That might've come with another several years of training natural, but you got on at just the right time I reckon.
BTW, your pecs look very thick. Do you do anything special for them? My chest is actually my strong point, and I'm of the Tom Platz school of bodybuilding: take your best muscle group and make it even better
