I recommend you smarten up and start doing your homework. You sound like you have done no research at all. You're asking the most basic questions.
Your last cycle was Deca and Dbol. I don't care how many stones you put on, this was reckless to say the least. You know nothing except how to put numbers and names together, yet you haven't a clue on what they do, what their roles are, or how to properly administer the most basic of compounds.
I suggest very strongly that you spend a significant amount of time reading, researching, and educating yourself before you consider using AAS again.
