Overcoming the Challenge of Confident Identification Among Two Related Groups of 17‐Methyl Steroids by GC–MS

Journal of Separation Science, Volume 48, Issue 12, December 2025.
ABSTRACT Tetrahydromethyltestosterone (THMT) and 20‐hydroxymethyl‐18‐nortetrahydromethyltestosterone (20OHnorTHMT) are metabolites of the anabolic androgenic steroids methyltestosterone and metandienone. Both molecular structures are used as markers in anti‐doping analysis. There are eight reasonable diastereomeric structures of each group relevant for
