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]

One thought on “Cannabaceae”

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
