Well I guess it's that much more of an accomplishment to be natural then. It's really not incredibly difficult to get up to around 200 and 10% bodyfat over the course of 3 years or so, regardless of genetics, given the right training and diet.
Go ahead and ruin your kidneys and liver, lose your hair, and shrink your balls all for a little more muscle that you could have gained naturally. I would say the vast majority of gear users are NOWHERE near their genetic potential, so don't even try to bring that argument up.
