so this little magical pill, i remember it well. I myself used to swear by it, I had taken this when younger and shed a ton of weight, but long forgot about it some how god only knows how/why) until, today when i saw it on Dr. Oz . it basically is in our bodies already, and thinner people produce more of it, we could get the same affect if we ate oh gee 90lbs of raspberries.. OR take 100 mg in morning of this, i think id take this... it pretty much tricks the body into thinking its thin, it truly does help the body naturally, no hard chemicals, or weird FDA needed research things in it, pure and simple, so look into it, of course diet and exercise is a must as well with any lifestyle change, i don't say diets for diets fail one needs a lifestyle change.
