NOXCG3 is just an overpriced creatine that isnt even proven to work better than normal creatine mono-hydrate.
My opinion would be to just keep taking your glutamine and whey protein and then also pick up some creatine monohydrate and mix that in with some grape juice and drink that. Should do you fine, just follow the directions and load etc. If you want a lot of creatine info visit Bodybuilding.com - The Future Of Bodybuilding! Huge Bodybuilding Site.
