Name: Norandrostenedione CAS NO: 734-32-7 EINECS: 211-995-8 Molecular Formula: C18H24O2 Molecular Weight: 272.38 Density: 1.13 g/cm3 Boiling Point: 433.4 ° C at 760 mmHg Melting Point: 169-172° C Flash Point: 433.4 ° C at 760 mmHg Standard: Enterprise standard Color: white powder Assay: 99.3% Package: 1kg/AL bag Descriptions: 19-Norandrostenediones (4-estrene-3,17-dione, NOR) is a precursor of the anabolic steroid nandrolones. Until 2005 19-Norandrostenediones was available without prescription in United States, where it was marketed as a prohormone, but it is now classified as a Schedule III drug. It is also banned from use in many sports, including the Olympic Games, under the World Anti-Doping Code.19-Norandrostenediones is readily metabolized to nandroloe after oral administration, but its potency to transactivate the androgen receptor dependent reporter gene expression is 10 times lower as compared todihydrotestosterone (DHT). Applications: Scientific studies have shown that oral administration of 19-norandrostenediones is "a very ineffective strategy for stimulating skeletal muscle mass increases but may be associated with side effects". In vivo experiments in castrated rats demonstrated that subcutaneous treatment with 19-norandrostenediones resulted only in a stimulation of the weight of the levator ani muscle, while the prostate and seminal vesicle weights remained completely unaffected. In contrast to its metabolite nandrolones, 19-norandrostenediones highly selectively stimulates the growth of the skeletal muscles but has only weak androgenic properties. In the early 2000s, contamination of androstenedioe products with traces of 19-norandrostenediones caused false positives for doping tests for nandroloe because 19-norandrosterones is a metabolite of both nandrolones and 19-norandrostened
