Most fat burning supplements are made with whatever ingredients are "hot" at the time, plus a bunch of worthless fillers. Unlike them, Sheer THERMO is made with science in mind. The Hordenine, 5-HTP, and caffeine stack together for enhanced fat-burning results. The Yohimbine increases adrenaline levels, and the Hordenine prevents it from being broken down. The Green Tea attacks belly fat, while Forskolin protects your muscle from being broken down.
