Nandrolone Decanoate (Deca 250mg)is a popular injectable anabolic steroid used by bodybuilders in the off-season for mass building. This 1962 formulation was first marketed alongside pharmaceutical giant Organon, who brought it out two years later after development started at their Heidelberg laboratories back in the 1960s. 

Deca was initially synthesized to treat patients suffering from cachexia (muscle wasting). It’s one of the only anabolic steroids still prescribed today, effectively treating HIV/AIDS and anemia. In addition, women can benefit from looking to build more muscle mass because of its erythrocytosis properties. 

By the 1970s’ Deca had become a popular adult-use hormone worldwide, with countless bodybuilders incorporating this anabolic steroid into their cycles.

Nandrolone Decanoate, also known as 19-nortestosterone, is a synthetic form of testosterone that belongs to the anabolic androgenic steroids (AAS) group. The compounds in this class all have nomenclature ending with “19 Nor” and are named so because they imitate or bind more strongly than naturally occurring hormones do; it’s not until you add up their carbon atoms together – such as through combustion – does something happen!

The primary role of testosterone in the human male is to aid the development and maintenance of muscle mass by synthesizing drugs like Nandrolone Decanoate, which have more anabolic properties than their counterparts. Regarding our sex hormones, these synthetic versions are better suited for those looking to bulk up quickly or put on weight without adding bulky muscles you can’t take off once they’re there (i.e., most steroids).

Nandrolone Decanoate initially synthesized and described by Birch in 1950, is an androgenic hormone with similar characteristics to testosterone. The only difference between Nandrolone and Testosterone is at carbon 19, where it lacks a methyl group; this affects how they are processed by your liver for safe storage in fat cells or release into circulation depending on what’s needed by the body. Due to its Demethylation at C-19, Nandrolone Decanoate has a strong anabolic but weak androgenic effect. As a result, its anabolism is much more potent than testosterone!
