norandrosterone

1. Norandrosterone 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. Traces of 19-norandrosterone may be naturally present in human urine. An experiment conducted on athletes showed that after a prolonged intense effort, the 19-norandrosterone concentration can be increased by a factor varying between 2 and 4,[3] but another study failed to replicate the result. Concentration menstruation. containing 19-nortestosterone, has been shown to result in the excretion of 19-norandrosterone in the following hours, so athletes should prudently avoid meals composed of pig offal in the hours preceding doping tests.[6] Consumption of boar meat, liver, 19-norandrosterone output also The consumption of edible parts of a non-castrated pig, increases in the urine of female athletes during kidneys and heart also increased http://www.creative-diagnostics.com/symbolsearch_19-Norandrosterone.htm
