text: The identification of LTMs of different anabolic steroids was accomplished by means of several different methodologies including fractionation and in-depth elucidation of urine samples collected from human administration studies6 ,7 and animal model elimination studies.8 ,9 A novel approach was recently presented, which is based on the administration of deuterated steroids followed by the identification of the respective deuterated urinary metabolites using hydrogen isotope ratio mass spectrometry.10 Owing to the enormous specificity and sensitivity of the MS analyser for deuterated substances (requiring as little as 0.5 ng/mL of analyte), urine samples are readily measured for target compounds showing prolonged elimination times and, thus, might support expanded detection windows and retrospectivity.
