A method based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the direct quantitation of endogenous steroid sulfates has been developed to be able to evaluate these metabolites as biomarkers to detect the misuse of endogenous androg

The detection of testosterone (T) misuse is performed using the steroid profile that includes concentrations of T and related metabolites excreted free and glucuronoconjugated, and the ratios between them. In this work, the usefulness of 14 endogenou

Anabolic androgenic steroids (AAS) are synthetic testosterone derivatives which undergo extensive metabolism in man. Differences in the excretion of phase II metabolites are strongly associated with inter-individual and inter-ethnic variations. Sulfa
