When I initially purchased this pill I was just taking a chance …this isn’t my first fat burner but I’m trying the Keto lifestyle and I’m seeking an aid to remain on the diet ..I definitely feel a boost in energy and as well as great appetite suppression which is why I got it in the first place …lost 9.2 lbs in 2 weeks although I still eat a few complex carbs ….give it a try you won’t be disappointed.
