I don't have much intelligence on this subject, (lol) but i know that there is no way for someone your age to buy it. And, does anyone know if it is even legal to buy at all? i'm unsure of that. But why in the world would you want it anyway. If you want it to speed up puberty, that is a huge no no. You should never try to speed it up, it could harm your body and taking steroids is unhealthy, not to mention deadly. Just don't worry about puberty, you will get through it alive, i promise.
