bro, if you are being serious and don't want to go the illegal route, go to your local 24 hour fitness and pick up the Ergogen Muscle Cell Volumizer. Take 10 pills a day for 1 month. If you dont gain at least 10 pounds I will reimburse you for the purchase. As far as the other stuff goes wieght gainer is just that wieght gainer not muscle gainer so who friggin knows where you will gain the wieght or what kind of wieght you will gain. But half of changing your body is expeirementing with different kinds of supps, so do what you want but be causious about everything. Good Luck too. Peace Out.
