Company description
19-Norandrosterone is a nandrolone and 19-norandrostenedione metabolite. It is created as a
byproduct of nandrolone via the 5-alpha reductase enzyme and is on the list of substances prohibited by the World Anti-Doping Agency since it is a detectable metabolite of nandrolone which is an anabolic steroid. Consumption of androstendione products contaminated with traces of 19-
norandrostenedione also results in testing positive for nandrolone.
