This is by no means a flame against you bro, but if you have been doing your research properly, then you should know what roids will "help" give you the results your looking for, or better yet what stack will give you what your looking for not the mention the possible sides that come along with them.
From what im gathering.. you say you know what steroids are and what they do, Well not all roids are created equal, but imo a deca/winny stack will prolly give you the results you are looking for.. im sure your gonna be told to throw some sort of test into that mix as well or to substitute the deca with test... Goodluck.
Oh yeah as im sure you know, diet is big key to achieving the results you want. If your diet sucks your not gonna gain or you might gain the wrong pounds.
Peace out.
