@Hyper I fear that you have a misconception of the information stated. We are not saying that you will not have great gains. We are saying that by using AAS prematurely you will limit your growth potential for one. From there each time you use AAS you risk shutting down your HPTA. It is basically inevitable that this will happen. The opinions that are given here are to inform you of risks due to your age and the harm. Most of us speak from experience and wish that we would have done things differently. If you are not aware this site has a great reputation and typically only gives sound advice. This has a lot to say. and you will not find users here that promote the use of AAS underage or Under educated.
