What Nandrolone is

Class and mechanism

Nandrolone is a 19-nor anabolic-androgenic steroid. A 19-nortestosterone derivative. Reduced to dihydronandrolone rather than DHT in 5-alpha-reductase target tissues, giving a different androgenic profile to testosterone. Progestogenic activity is a documented feature of the 19-nor class.

Where it sits

Injectable compounds are supplied in oil. The ester attached to the molecule sets the release profile, which is why the same base compound appears under several different names.

Other names

Nandrolone is also written as Deca, 19-nortestosterone and NPP. The same molecule appears under more than one name, which is worth knowing when comparing listings between suppliers.

Others in the injectable compounds range

Nandrolone sits in the injectable compounds group. The compounds below share that grouping, which is the useful starting point when comparing one against another: same group means the comparison is like for like, different group usually means it is not.
