19-Nor-5-androstenedione, also known as estr-5-ene-3,17-dione, is a synthetic, orally active anabolic-androgenic steroid (AAS) and a derivative of 19-nortestosterone (nandrolone) that was never introduced for medical use.
19-Norandrosterone, also known as 5α-estran-3α-ol-17-one, is a metabolite of nandrolone (19-nortestosterone) and bolandione (19-norandrostenedione) that is formed by 5α-reductase. It is on the list of substances prohibited by the World Anti-Doping Agency since it is a detectable metabolite of nandrolone, an anabolic-androgenic steroid (AAS ...
19-Nor-5-androstenediol, also known as estr-5-ene-3β,17β-diol, is a synthetic, orally active anabolic-androgenic steroid (AAS) and a derivative of 19-nortestosterone (nandrolone) that was never introduced for medical use. [1] [2] [3] It is an androgen prohormone of nandrolone and of other 19-norandrostanes. [1] [2] [3]
Nandrolone, also known as 19-nortestosterone (19-NT) or as estrenolone, as well as estra-4-en-17β-ol-3-one or 19-norandrost-4-en-17β-ol-3-one, [43] is a naturally occurring estrane (19-norandrostane) steroid and a derivative of testosterone (androst-4-en-17β-ol-3-one). [2] [12] It is specifically the C19 demethylated analogue of testosterone.

19-Nordehydroepiandrosterone (19-nor-DHEA), or 19-nor-5-dehydroepiandrosterone (19-nor-5-DHEA), is an estrane (19-norandrostane) steroid which was never marketed. [1] [2] It is the combined derivative of the androgen/anabolic steroid nandrolone (19-nortestosterone) and the androgen prohormone dehydroepiandrosterone (DHEA, or more specifically 5-DHEA).
Due to longstanding pushback and controversial health studies surrounding the ingredient, many processed food manufacturers have already shifted away from using Red Dye No. 3, opting instead for ...
A steroid with modifications away from testosterone in one or both of these areas is commonly referred to as a "prohormone". These enzymatic changes occur with the body's bidirectional enzymes.
