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).^[1][2] 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.^[2][3][4] 19-Nor-DHEA may occur as a metabolite of bolandione and related steroids.^[2]
