It's kindof like in a way, not me working out but the pill. Put this in perspective, it contains an amino acid called Arginine alpha-Ketoglutarate (A-AKG), which helps trigger hormones in your body that amplifies your muscles. It also contains something called the phylex delivery system which helps the A-AKG flow through your body more efficiently. I am no expert, but me and my friends have tried several Nitric Oxide supplements and N02 from GNC has been the most efficient throughout my group of friends and myself. I've been using for about 5 months and I do advise a 2 week cycle every 2 months or so. As for rumors on keeping your muscles go, your muscles DO NOT deflate or change once you get off them. I have never used creatine mainly because it mimics a chemical called ATP found in your liver which helps mulsce growth but long-term side effects of creatine are unknown, soo I dont want to find out down the road that creatine corrupts the liver, a very very important part of your body.

In general, N02 from GNC is a positive if you can afford it.
