Too many people want to delude themselves into thinking that they're just a few syringes away from a Sandow. But once these guys start injecting but look nothing like the pros they wish to emulate, they'll either blame genetics or declare that the pros were taking even more than they were (despite those wanna-bes duplicating that "pro stack").
That's simply not the case.
I've met my share of people, who you'd never know were using anabolics unless they told you, because they certainly didn't look the part.
No one is comparing themselves to pros, look at the posts, many are saying how important drugs are and how much pros like to downplay the effects it has on a physique.
Genetics or not pros take a lot, a lot more than local gym rats do
First and for most, genetics, response, longevity is the key to successful pro, then come the others
