I asked my dad about it when I was a Junior in high school (16 years old). Several of the guys I knew were doing it. He took me to a pharmacist that he was friends with. This guy was ripped and admitted he took steroids. He talked to my dad about the good and the bad. In the end my dad decided it wasn't worth it. So I waited until I was 20, got my own and didn't know shit about taking them. I got lucky though and didn't have bad side effects. Would it have been better if he had gotten them for me and gotten me supervision? Tough call. One thing to remember is eventually your kid will find a way to get what they want and they won't be as responsible as you might. Very tough call.
