Okay, giving the benefit of the doubt to most of those guys, the first two are highly suspect. In fact, I'd bet the bank they are either on, or have been on and learned to keep the enhanced muscle. Not that amazing gains can't be made with it, but gear gives a look -- a density and depth, a thinness of skin that is, well, steroidal. Those guys have it.
I've made the point that you can look great with very little gear, and you can look very good with no gear. But to suggest you can look like a hardcore roidhead naturally...mmmm, I have to say, it may backfire because it's so unlikely.
