I am a gym goer as well, and I take N.O. xplode, plus I add in Creatine to my N.O. xplode. If you are looking to gain muscle, I would encourage you to consume one gram of protein for every pound you weigh. It is difficult to do it everyday, but at least do it on gym days. I also take Cell Mass by BSN, it contains Glutamine and other things that help you recover from an intense workout. I also add Glutamine to my Cell Mass as well. Reforming your diet is the only way to achieve great results, so if you do not adjust your diet and consume enough protein it will be very hard to gain in muscle mass. The supplements are just helping me recover quicker so I can make it into the gym 5 days a week .
