No, that isnt it at all. I think that most teens gear for the wrong reasons, they really dont know what their getting themselves into.
Unless you are deadset on becoming a pro in the sport then I'd say go ahead, but ask yourself do you really have what it takes at such a young age? Are you willing to sacrafice?, because I dont think many are, most teens just want to party, pick up chicks and have a good time with mates.
I've come across very few youngins who were well experienced in factors like diet, supplementation and training. If you want to take AAS I suggest wait until you get your priorities in order, because the last thing you need is added stress of side effects in your system, especially depression at a young age!
I might sound like a repetitive fool but AAS are not a magic bullet, they're simply an aid. Most of your gains will come from diet and rest, without those ingredients you're simply going to end up back where you started with a higher blood pressure maybe some acne and definite depression.
Thats why experiece is everything when you play the AAS game, you take what the vets have to say and absorb it then its up to you where you go from there.
