I did google it and I can't get a profile on it. Someone said that it is like primo but hurts to inject it. I didn't know if anyone has ever tried it and could give me some info on how well it works.

The term prosteroids is used in the supplement industry to make products sound much cooler and effective. In truth it is a term that denotes an active hormone that may or may not be subject to enzymic alterations. Yup, in short it means an actual anabolic-androgenic-steroid (AAS) that has not as of yet been classified as a controlled substance. Examples are 1-Testosterone, Testosterone-OH and Nandrolone-OH.
