It isn't just how much time you have been bodybuilding that matters, it's how much bodybuilding knowledge you have that matters most. You can gain alot of bodybuilding knowledge in two years, but not that much practial knowledge as in from learning from trial and error, from listening to your body and what works best for you, what excercises and nutrition practices that work best for you, and not getting all of your bodybuilding knowledge just from books. If you take a guy that has been bodybuilding for 5 years naturally and take a guy that has been bodybuilding for 2 years naturally, and they have the same knowledge at bodybuilding, than that would be okay to use AS. But in most cases, you cannot get as much practial knowledge as the guy who has been bodybuilding for 5 years.
AS use should be only a enhancement to bodybuilding, they do not make the bodybuilder. A natural bodybuilder who has been in the game along time has a better feel to how to shape his body, what excercises work for him and knows how to train properly. When you bodybuild naturally you are forced to know your shit, or you will not grow, it's as simple as that. But if you take a person who uses AS without that much knowledge, he is not in tune in what works for him, with training and nutrition, because the AS cover up for his lack of knowledge. He might gain 20lbs off a cycle, but the more seasoned bodybuilder might gain 30lbs. I am a perfect example to wait. I went from 150lbs to 237 naturally in four years at a height of 6'0. My friend took up bodybuilding three years after i started. And in two years he went from 165 to 250lbs due to using AS the whole time, I think he used about five cycles. He has not been able to use AS in about 9months and he is now about 215lbs and he looks like shit. I am now a solid 288lbs after just two cycles. Had he had the knowledge I have, or would have been bodybuilding as long as I have he might have been able to keep most of his weight, since he did not, he now looks like a piece of shit.
