This study found that chronic administration of finasteride affected the isotopic composition of testosterone and nandrolone metabolites, impacting the drug-testing outcomes in athletic contexts.

This study found that finasteride significantly alters urinary steroid profiles, complicating the detection of steroid abuse in doping-control analysis by potentially causing false-negative results.

This collection from the 2021 Manfred Donike Workshop outlines advancements in doping detection, highlighting new test methods and challenges, with a focus on steroidal substances, peptide hormones, and gene doping analysis.

In this study of patients with androgenetic alopecia taking off-label low-dose oral minoxidil, adverse events like dizziness/lightheadedness, hypertrichosis, and extremity edema were observed in 14.9% of patients, with females experiencing more adverse events; higher doses increased dizziness risk, leading researchers to recommend cautious dosing approaches.

This study used a zebrafish model and advanced mass spectrometry to identify 11 metabolites of epristeride, revealing significant effects on purine metabolism and aromatic amino acid biosynthesis, which may aid in developing anti-doping detection methods.
