Analytical strategies based on mass spectrometric techniques for the study of steroid metabolism

Anabolic androgenic steroids (AASs) are synthetic substances derived from testosterone, whose use in sports is prohibited. This review underlines the advantages and the drawbacks of different coupled mass spectrometry-based approaches to the identification of MS metabolites. We discuss diverse aspects of the applications in the doping-control field, including sample preparation and instrumental analysis, with special emphasis on the potential scope of each strategy.
