Be careful - even if you use a non-aromatizing AAS, you'll still have to do PCT (you ARE going do PCT aren't you?). Since both nolva and clomid are SERMs, they emulate estrogen and will make your body think that its estrogen levels are high. So even with 'safe' AAS, PCT may be enough to cause your grwoth plates to prematurely fuse.
IMO if you're still growing, the risk/reward ratio is too great to justify using AAS. You're already enjoying the highest natural levels of testosterone and HGH that you'll ever have in your life. Why not make the most of this for a couple of more years until your're done growing and then you can use AAS with far fewer risks. The only execption I could see would be if there was a division I athletic scholarship in the balance, but even then....
