I have sold this pill-alot-with very few returns. It has a fiber in it that helps curb appetite as well as a fat burner. You can adjust the pills if you are sensitive to caffeine. It is not one of the higher caffeine filled products. Most women noticed weight loss in their legs. Water is needed in taking with the pills. If water is not taken the pills can become a choking hazard.The fiber swells in the stomach to create to fullness feeling.
