I'm 18 years old, 6'4" about 200 lbs. Right now I'm taking 100% whey protein and creatine monohydrate. I lift a pretty good amount of weight, but I'm looking to get and look stronger. Some people at the my local gym were telling me about some pill called NO2. I guess it works really well and by the people looked who were telling me about it, it looks like it works well. Does NO2 really work like they say it does? If it does I'd be interested in taking it, but I heard it's pretty exspensive. Any suggestions? Thanks.
