This is absolutely insane. I've been bodybuilding for 10 years. I workout 9 times a week. I have a crazy strict diet. I have abs, and consider myself someone with a good amount of mass. Spending this much time in the gym, I know plenty of people like myself. To say "they're all on roids" is something a lazy person would say as a reason why they can't accomplish that. I've never taken roids and I never plan to.
Nutrition, weight gain/loss, is all science. Roids are not needed. It's just hard work and commitment - something most people do not have.
Becoming huge take someone who is an "easy-gainer," very patient (like 10 years), dedicated and works with their body. The body adapts to what you give to it, give it enough of it, and you'll see those adaptations.
ultimately its about incentives. The fitness industry is a SHAM. Most supplements will not work unless they are some form of endogenous test. Creatine what a joke.
At the end of all this I am not promoting living a non-healthy life style. There are wonderful benefits to moderate cardio and low calorie diets.
I can go on and on and on. But I just hate not having the truth out there and the whole world fooled.
Lyle mcdonald at www.bodyrecomposition.com is the real deal. The guy has great advice and he is a no nonsense dude. The only thing we disagree on is natural growth. I feel as if his assumptions for growth are too high. www.steroidology.com is another great site for users and non. I work with a few natural folks and some add 20 lbs but it is not that noticeable (b/c its never pure lean body mass). The only way to naturally mimic roid effects is through protein timing which has a 1% success rate.
Reality is, what you want to look like is impossible. If you want to shed 20 lbs of fat sure thats doable naturally but achieving a sick looking fitness cover body requires 250 mgs of test to the upper right glute area twice a week. Good luck folks.
