      The misuse of the anabolic steroid methyltestosterone is currently routinely monitored in doping control laboratories by gas chromatography-mass spectrometry (GC-MS) of two of its metabolites: 17α-methyl-5β-androstane-3α,17β-diol ...
    • closedAccess   Detection and structural investigation of metabolites of stanozolol in human urine by liquid chromatography tandem mass spectrometry 

      Pozo, Óscar J.; Van Eenoo, Peter; Deventer, Koen; Lootens, Leens; Grimalt Brea, Susana; Sancho, Juan V; Hernandez, Felix; Meuleman, Philip; Leroux-Roels, Geert; Delbeke, Frans T. Elsevier (2009)
      The applicability of LC-MS/MS in precursor ion scan mode for the detection of urinary stanozolol metabolites has been studied. The product ion at m/z 81 has been selected as specific for stanozolol metabolites without a ...
