its a glucagon like peptide. We use Byetta at the hospital. This is a new Brand. Nothing scary at all. Users report a lot of weight-loss b/c it causes satiety. When you consume sugar, this drug (half-life 12hrs, only need one doase daily) causes your pancreas to secrete insulin as a response. Sort of making the Beta cells more sensitive like you want your muscles to be sensitive to insulin. As for bodybuilding, this would help a lot for dieting but Metformin would be better b/c it also casues satiety and with the right dose would work better.
