I'm 19, 5'11' 165 lbs. and looking to add 15+ lbs. of muscle this summer (3 months) while I'm out of class and have sufficient time to have a serious workout/eating routine. Last summer I bulked up from 145 to 165 in two months only on Cell Tech and Nitrotech, and when I left for college in the fall and stopped taking the supplements I expected to lose most of the weight I had put on but surprisingly did not. I have also used a tub of NO-Xplode but saw no results beyond the energy surge and very short lived muscle pumps, so I do not plan on using this again. Are there any other benefits from using nitric oxide? I plan on taking some form of GNC brand creatine (instead of paying for brand names) and hitting the protein shakes hard but what other supplements will make my bulk up more effective?
