19-Norandrosterone is a steroid that is used in the treatment of breast cancer. It has been detected in urine samples of women and men at levels that were comparable to those found in athletes who had taken nandrolone. 19-Norandrosterone is also used as a control substance for analytical methods such as LC-MS/MS, which can be used to detect other steroids such as testosterone or nandrolone. The detection time of 19-norandrosterone is approximately 2 hours.

Applications 19-Norandrosterone is the oxidized byproduct of Nandrolone (N315000), an anabolic steroid that is present naturally in the human body. References Jiang, J.Q., et al.: J. Food. Sci., 77, 63 (2012); Delgadillo, M.A., et al.: J. Chromatograph. Anal. Technol. Biomed. Life. Sci., 897 (2012);
