Drug Testing and Analysis, Volume 16, Issue 6, Page 604-615, June 2024.Novel fully A‐ring‐reduced metabolites of methyltestosterone were predicted and synthesized on a microscale. Their GC‐MS/(MS) behavior was studied to develop a targeted detection method. Targeted analysis of methyltestosterone HepG2 cell incubation supernatants and post‐administration urine samples confirmed the presence of these novel ...
