first, the big mistake is starting too early, like 19-24. the second thing is thinking steroids are the answer to everything their not but they're a great tool for enhancing your body and performance, thirdly having a good pct in place for after your cycle and also have an AI on hand before starting your cycle, you need to have everything in place before you start your cycle imagine you only had two bottles of test but you needed three and your supplier has run out as well bang goes you cycle or you start getting gyno and have no AI bang titties, you get the point. the other thing is to do your research knowledge is power no about the possible side effects no what the onset of gyno feels like etc. and for your first cycle well it has to be 400-500 mg of test e or c a week split into to injections. good luck.
