FAT BITCH

Viper is the "hardcore" fat burner brought to us by Dymatize Nutrition, a company that's built its reputation manufacturing no-nonsense body building supplements like protein powders, weight gainers and branched chain amino acids among others.

By the looks of things, Phenphedrine appears to be brought to us by the same anonymous retailers that introduced us to such dubious weight loss favorites as Fenphedra and Nuphedragen. The last two products sport nearly identical formulations—and Phenphedrine features the same core group of ingredients, plus a couple of extras.
