Well if it aint the very first NO product i have ever taken. This just might be the worst NO product on the market and i aint kidding. This product's existence is what forced me to give Pump tech my Muscle tech a 2 overall. Just because this is much worse. Imagine taking these pills, hitting the gym, and feeling nothing at all. If that is what you are looking for than this is the product for you. Pinnacle oughta pay folks to take these pills.
