Food, exercise, and sleep are your best friends for your age - use them. If I were 17 again and knew what I know now I would not even consider using hormonal supplements or the like.
You can get much better results using what your body is giving you naturally at your age. Focus on your diet and exercise plan now and build a solid foundation. In fact, you should start a log in the Invalid Link Removed section and I'm sure you'll get support and encouragement from this forum.
AX guys, sorry about posting this in your forum, but I think I should: NoRemorse, go to Invalid Link Removed and read the online books - they are free! I am certain you will find something that is useful to you with sufficient direction on how to do it without hormonal supplements.
All that said, you should get your parent's permission to do all this. I know it sounds corny, but better safe than sorry.
P.S. I am not a scivation rep, I just like their online books - they are useful.
