Hmmm, i'm kind of offended by all this talk of teens being immature and not understanding the detrimental effects of AAS... I'm 17 and have done over a years research on not only AAS, PH, AI, but almost all test affecting drugs. Still, i would consider it very unwise for a teen to even consider using an AAS/PH simply because it is uneccesary. I've been lifting with kids on PH's and pharmacuetical AI's. There are plenty of natural alternatives which are safe and can provide the same results in the long run. I've noticed kids taking PH's gains dwindle down quickly after discontinuing. My advice to my fellow teens would be to stick to the basics. ZMA, Protein, creatine, PWOs and ofcourse a clean diet. I think it is important for teens to realize that they can get healthy rediculous gains because they are in their prime and that AAS are simply not necessary, before even taking the risks into account. It is not rare for a teen to gain 30+ pounds in a year without the use of any AAS or PH while for adults these kinds of gains are unheard of. So why take AAS as a teen if you can get comparable results by being legit? There is no reason.
