The definition of definition. Powered by a potent fat burning engine that contains two powerful phases for even better six-pack support. Our Thermo Burn Complex delivers muscle revealing fat reduction agents, FAST. Then, the Extended Release Matrix kicks in to help keep metabolism revved and further fuel the burn. New Ripped Fuel also addresses a dirty little secret of weight loss: burning fat releases fat-stored toxins-what we call "cellular pollution"-that can damage healthy cells. To combat this, our new formula uses milk thistle to support liver function and aid the body's natural detoxification process during weight loss.
