Look bro you have to give us your stats...i.e. age/weight = 165lb/bf%/height. You also need to research the shit your doing. Im talking research before you make any posts what-so-ever! The questions you asked you can find answers to if you researched. You have to realize that you are about to begin fuking with your endocrine system...shit is not a game and demands respect. Its not like learning to ride a bike where you just need that one push to get you going...you should become an expert at knowing what you are putting in your body and what its effects, good or bad, are. Im only telling you this because I am tired of guys looking for an easy way to take aas without doing their own work first.
