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
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-norandrostenedionse. In a randomized
controlled trial trace contamination of androstenedion with
19-norandrostenedie was sufficient for users of androstendioe to
test positive for nandrolones.This detail became less relevant
after 19-norandrostenedie and androstenediones were banned by major
