John: There is no scientific evidence that these products do anything as far as muscle building. These products are based on an effect seen in cardiac patients and then extrapolated to muscle building. The research is taken completely out of context, don’t waste your money.
Brad: Depends. In my opinion unless they contain creatine I wouldn’t bother.
Rusty (Follow-up): I always thought this product was questionable. It is hyped pretty hard right now.
John: Yes they are hyped because there hasn’t been a true innovative breakthrough muscle building product since creatine monohydrate over 15 years ago. The supplement industry is just grasping onto anything marketing story it can to sell something new. And the nitric oxide story is a good one, unfortunately the research shows that it doesn’t do anything. That is why nitric oxide products are becoming combination products mixed with creatine as Brad mentioned. By mixing the two products together supplement manufacturers know the creatine will give the customers some real muscle building effects but they can charge more than regular creatine because they’ve also added the nitric oxide boosters in there.
