LOL the only supplement that is gonna pack on honest to god muscle would be...well its not a supplement. Its called brown rice, chicken, steak, pasta, whole wheat bread, potatoes. That is gonna give you solid permanent gaints. The only supplements you need from there are creatine of some sort and a good protein shake. I'm partial to Muscle milk Cookies and Cream, but after reading a thread here I tried Cytogainer Chocolate Mint, and its just deliecious. Its great to pack on a few extra calories but never rely on them to put on weight. Think about it solid food=muscle mass liquid=well fucking liquid.
