General description
19-Nor-4-androstene-3,17-dione is an anabolic steroid used in dietary food supplements.
Application
19-Nor-4-androstene-3,17-dione may be used as a reference standard in the determination of 19-nor-4-androstene-3,17-dione in dietary supplements using liquid chromatography coupled with tandem mass spectrometry (LC-MS-MS).

The dietary supplements 19-norandrostenedione and 19-norandrostenediol are potential metabolic precursors of nandrolone. They are considered by law in the United States as prohormones without proven therapeutic, curative or diagnostic properties, and therefore available as over-the-counter drugs. Oral dosages of 0.1-1

One of the most frequently misused steroid precursors (prohormones) is 19-norandrostenedione (4-estrene-3,17-dione, NOR), which is, after oral administration, readily metabolised to nortestosterone, also known as nandrolone (durabolin). In this study we have characterised molecular mechanisms of its action determined its

The purpose of this study was to determine the effects of norsteroid supplementation (224 mg of 19-nor-4-androstene-3,17-dione and 120 mg of 19-nor-4-androstene-3,17-diol, total daily dose = 344 mg) on body composition and strength in resistance-trained men. In a placebo-controlled, double-blind
