I give it a 3 not because it doesn't work because it does give you intense concentration, good pumps and fantastic focus. The problem I had with it was INTENSE gut cramping and numerous unpleasent trips to restroom later in the day. I was taking two scoops and the side effects were horrible, especially when you are in meetings at work or on the road. I backed down to one scoop and still have side effect but not as intense. I have been taking supps for years as well as protein products and this is the first time I have had such shit fits. Buy with caution! |
