It's not a yes or no question. You are the only one who knows if your ready to start using AAS or not. I personally started a little to early (started at 19 maybe a little shy of that) and if I could go back I may have waited another year but I don't regret it. I had years of training under my belt at the time and made some very good progress naturally so I figured I would take the plunge. Do your homework, talk to the bro's on here about there experiences and then make an educated choice. Best of luck to you bro!
