In short
From the info I was given, the cell is receptive to 4 different types of AAS. Each steroid falls into either of these 4 catagories. If you take too much of one catagorie, the excess wont be as asborbed as easily and will basically be wasted. the basic idea is to take a little amount from each of the 4 catagories, instead of a lot fron one or two catagories. When I posted this a few days ago, the pro that gave me this info told me that it wasnt for me to share, he worked long and hard obtaining this info and didnt want me handing it out on here.
