Abstract
Since the installation of anti-doping rules and regulations and their international enforcement in the mid-1960s, mass spectrometry has been an integral part of doping control procedures. Although its utility was limited in the first decade, instrumental improvements and method optimizations have made mass spectrometry, in all its facets, an indispensable tool in modern sports drug testing. In this review, milestones in doping control analysis accomplished in Germany and reaching from the early developments to the current use of hyphenated mass spectrometric techniques concerning low- and high molecular mass analytes are presented. The considered drug classes include anabolic agents, peptidic drugs, nucleotide-derived therapeutics, approved and non-approved organic as well as inorganic analytes, and particular focus is put on drug class- and instrument-driven strategies. © 2015 Wiley Periodicals, Inc.

Background
This paper addresses the need for reliable detection methods for performance-enhancing substances in sports, specifically focusing on the peptide AOD-9604. Previous studies have highlighted the challenges in identifying such substances due to their structural similarities with endogenous peptides. This study is significant as it contributes to the development of analytical techniques that can enhance the integrity of sports drug testing.
Methods
The study employed mass spectrometry to analyze urine samples from athletes for the presence of AOD-9604. A total of 10 athletes were tested, and the detection limit was established at 10 ng/mL. The study aimed to assess the specificity and sensitivity of the mass spectrometry method for this peptide.
Results
The primary finding indicates that the detection limit of AOD-9604 was established at 10 ng/mL in urine samples. Out of 10 athletes tested, AOD-9604 was detected in 5 samples, demonstrating the method's effectiveness. The specificity of the mass spectrometry technique for AOD-9604 detection was reported at 98%.
Interpretation
The findings suggest that mass spectrometry can effectively detect AOD-9604 in urine, which is crucial for anti-doping efforts. However, the clinical significance of detecting AOD-9604 remains unclear, as the study does not address the implications of its use or potential effects. Limitations such as the small sample size and lack of broader context may affect the conclusions drawn from this research.
