Detection of Testosterone Esters in Urine: Evidence of Trace‐Level Detectability in Doping Control Samples

Drug Testing and Analysis, EarlyView.
An ultrasensitive LC‐MS/MS method for detecting testosterone esters (T‐esters) in urine at sub–pg/mL levels is presented. This approach, employing Girard P derivatization, provides the first evidence of T‐esters' trace‐level detectability in human urine.

Reproducibility of Serum Androgen Concentrations by Liquid Chromatography Mass Spectrometry in Healthy Male and Female Athletes

Drug Testing and Analysis, EarlyView.
Box and whiskers plots show the distributions of serum testosterone (T), dihydrotestosterone (DHT), androstenedione (A4), and the ratios of T/FDHT and T/A4. ABSTRACT Detection of androgen doping relies on mass spectrometry‐based methods to detect natural endogenous and exogenous androgens in urine and serum. To distinguish exogenous administration from

Quantification of the Carboxylated LGD‐4033 Long‐Term Metabolite in Human Micro‐Dose Excretion Study Urine Samples

Drug Testing and Analysis, EarlyView.
A validated LC‐HRMS/MS method enabled the first quantitative determination of the LGD‐4033 long‐term metabolite (M5‐b) in urine following controlled micro‐dose administration. The generated urinary reference data support the interpretation of adverse analytical findings and anti‐doping result management. ABSTRACT Selective androgen receptor modulators (

Antidepressant Misuse in Esports: A Review of Pharmacology, Adverse Effects, Pharmacokinetics and Biomatrix‐Based Detection for Anti‐Doping Applications

Drug Testing and Analysis, EarlyView.
This review highlights the misuse of antidepressants as potential cognitive‐enhancing agents in Esports. Despite pharmacological effects that overlap with those of psychostimulants, antidepressants remain an under‐recognised source of doping in Esports.

Strategic Priorities for Advancing Eating Disorder Risk Reduction: A Narrative Review

International Journal of Eating Disorders, EarlyView.
ABSTRACT Despite decades of advances in treatment, eating disorders continue to impose substantial individual and societal burden, underscoring the need for earlier and more effective risk reduction. Prevention research has expanded considerably, producing a wide range of approaches that target modifiable risk factors, build individual coping skills ...
