In order to decrease the possibility of a false positive test, the IOC is contemplating on using a new method of detection based on a comparison between the carbon isotope ratio (13C/12C) of testosterone metabolites and those of testosterone endogenous precursors (Shackleton et al. 1997a, Shackleton et al. bodybuilding woman Steroid dealers. 1997b). This technique relies on the fact the synthetic testosterone has a different carbon isotopic signature than natural testosterone. A similar approach can be use for determining the use of exogenous nandrolone and the nor-prohormones. As such the use of carbon isotopes in nandrolone metabolites can also be used to differentiate between exogenous and endogenous 19Na and 19Ne making up for various uncertainties about the variations in urinary NA concentrations due to physiological and pathological conditions. As well, ways may be found, because of the differences in metabolite excretion, of differentiating the use of nandrolone as against the nor-prohormones. Another method, that seems to be able to detect the prior use of nandrolone even if urine testing is negative, is hair analysis. The presence of nandrolone in hair could be used to substantiate the exogenous use of nandrolone since endogenous nandrolone levels exist as an intermediate product that is converted in whole to it's metabolites including NA and NE, and as such are too low to be detected in serum, urine or hair. ConclusionsThere are several factors that could impact on nandrolone and nor metabolite formation and excretion resulting in the elevated levels of NA and NE.
