Nandrolone

19-Nortestosterone (NT)
Nandrolone (19-nortestosterone) is an anabolic steroid. Nandrolone is most commonly sold commercially as its decanoate ester (Deca-Durabolin) and less commonly as a phenylpropionate ester (Durabolin). Nandrolone decanoate is used in the treatment of osteoporosis in postmenopausal women (though now not recommended) at a dose of 50 mg every three weeks. It is also used for some aplastic anemias.
Nandrolone use is directly detectable in hair or indirectly detectable in urine by testing for the presence of 19-norandrosterone, a metabolite. The International Olympic Committee has set a limit of 2.0 μg/L of 19-norandrosterone in urine as the upper limit,[2] beyond which an athlete is suspected of doping. In the largest nandrolone study performed on 621 athletes at the 1998 Nagano Olympic Games, no athlete tested over 0.4 μg/L.
