Phentramin is some sick stuff, its legal speed. There are weight loss clinics that prescribe it. It burns muscle just as fast as it does fat and soon as you come off it you gain the weight back. I took some for a month or so about 4 years ago and dropped 35 lbs without changing a thing in my diet and doing no exercise at all. I had the worst case of dry mouth ever, even worse than what var does to me, and a pretty bad case of roids to boot. I believe it is also called Adipex
