I have tried this it will mainly give u a lot more energy to go to the gym and work a little harder without getting tired. I felt like it also made me less hungry. I lost five pounds in the month I took it and that isn't with changing my diet. So with a healthy diet it will help you slim down for sure. Only negatives the taste after about a week started to taste like crushed pills to me and it was kinda strong at first made my stomach hurt. Start with half a scoop and work up.
