IMO - You need to do a LOT more research before taking gear. You are messing around with the basic hormone chemistry of your body and you need to know what you are doing. Asking on these boards is a good start though!
Make SURE you do your research on the prevention of the sides from AS use, Nova, Arim, Propecia, Milk This. etc. The last thing you want to do is to grow a nice rack and lose your hair in the process. (I only say this because it does not sound like you know your stuff yet - LOL)
Read, Read, Read BEFORE you start taking...
