19-Nordehydroepiandrosterone (19-nor-DHEA), or 19-nor-5-dehydroepiandrosterone (19-nor-5-DHEA), is an estrane (19-norandrostane) steroid which was never marketed. It is the combined derivative of the androgen/anabolic steroid nandrolone (19-nortestosterone) and the androgen prohormone dehydroepiandrosterone (DHEA, or more specifically 5-DHEA). Related compounds include 19-nor-5-androstenediol, bolandiol (19-nor-4-androstenediol), and bolandione (nor-4-androstenedione), which are all known orally active prohormones of nandrolone. 19-Nor-DHEA may occur as a metabolite of …

Dehydroepiandrosterone/dehydroepiandrostenedione (DHEA, more correctly didehydroepiandrosterone), also known as androstenolone as well as 3β-hydroxyandrost-5-en-17-one or 5-androsten-3β-ol-17-one, is an important endogenous steroid hormone. In its pharmaceutical drug form it is called prasterone (INN). It is the most abundant circulating steroid hormone in humans, in whom it is produced in the adrenal glands, the gonads, and the brain, where it functions predominantly as …
