It used to consist of 334mg ephedra, 910mg guarana, 100mg l-carnitine, and 200mcg chromium, in short a highly caffeine packed diet pill that would cause severe side effects and in some cases even death, heart attack, or stroke in some individuals. As such, it was banned with the rest of ephedra products and its sales were discontinued. It was replaced by Ripped Fuel Extreme. But as with many other formerly ephedra based products, it seems Ripped Fuel has never quite recovered.
