I have used the entire bottle of this product. I have not experienced weight loss while taking it, however it has kept me regular, no bloating and no weight gain even while eating everything and not watching my diet. Once I stopped taking the product I noticed I started gaining weight and have become extremely bloated. I can honestly say that the product definitely works and on my next bottle I will start excercising and watching my diet, I am positive that I will see weight loss. The best part of this product is you only take 1 pill twice a day and NO SIDE EFFECTS!!!
