19-Norandrostenedione refers to two steroid isomers that were once marketed as dietary supplements and mainly used by body builders. After 2005, 19-Norandrostenedione was regulated in the United States as a schedule III controlled substance, as well as banned from use in competitive sports by the World Anti-Doping Agency. In the body 19-norandrostenedione is rapidly metabolized into nandrolone, also known as nortestosterone.

Cơ Chế Tác Dụng : 19-Norandrostenedione refers to two steroid isomers that were once marketed as dietary supplements and mainly used by body builders. After 2005, 19-Norandrostenedione was regulated in the United States as a schedule III controlled substance, as well as banned from use in competitive sports by the World Anti-Doping Agency. In the body 19-norandrostenedione is rapidly metabolized into nandrolone, also known as nortestosterone. 19-Norandrostenedione may be metabolized to 19-nortestosterone in both men and women. 19-Norandrostenedione, also known as nandrolone, is the basic substance of some very popular injectable anabolic steroids, however 19-norandrostenedione is not metabolized to testosterone. Whether or not increases in 19-nortestosterone levels would be sustained long enough by taking 19-norandrostenedione to show an increase in nitrogen retention and muscle strength and mass is unknown. 19-Norandrostenedione has also been shown to bind to androgen receptors with high selectivity. Transactivation of androgen receptor dependent reporter gene expression was 10 times lower than that produced by dihydrotestosterone. [1]
Dược Động Học :
▧ Absorption :
Absorption appears variable, but some absorption does occur.
▧ Metabolism :
Specific metabolites of 19-nor-5-androstene-3, 17-dione are 19-nordehydroandrosterone and 19-nordehydroepiandrosterone.
Chỉ Định : The claim that supplemental 19-norandrostenedione has anabolic effects is unsubstantiated.
