I would say that nitric oxide products do absolutely nothing. I have tried a few, including some samples of Pump-Tech, and got nothing. Since the price is so steep, you'd get twice the results directing your funds into protein, creatine, and a carbohydrate for postworkout.
The best PUMP I've ever gotten was when I combined 1 serving of Vitargo with 4 grams of CEE.. WHOA!!
