Supercritical Fluid Chromatography for Expedited Sample Clean‐Up in Isotope Ratio Mass Spectrometry Including Cholesterol as New Endogenous Reference Compound

Drug Testing and Analysis, EarlyView.
Supercritical fluid chromatography was employed in the sample preparation for IRMS determinations in sports drug testing for the first time and the developed method was successfully validated. Cholesterol (CHOL) was introduced as a novel endogenous reference compound and population‐based Δ‐values were established as shown here.

Impact of Drone Versus Car Transport on Anti‐Doping Sample Integrity Over Short Distances: A Proof‐Of‐Concept Study

Drug Testing and Analysis, EarlyView.
This proof‐of‐concept study evaluated the impact of short‐distance drone transport on anti‐doping sample integrity compared with traditional car transport. Targeted assays and untargeted metabolomics revealed equivalent biological profiles between methods, confirming that drone delivery preserves sample integrity for the athlete biological passport ...

Detection and Excretion Profile of Retatrutide in Human Plasma and Urine by LC-HRMS: Implications for Antidoping Analysis. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Retatrutide (LY3437943) is a novel long‐acting triple incretin receptor agonist that targets the glucagon‐like peptide‐1 receptor (GLP‐1R), glucose‐dependent insulinotropic polypeptide receptor (GIPR), and glucagon receptor (GCGR). Its pronounced effects on body composition and metabolic health, combined with increasing off‐label use

Simultaneous Detection of Steroid Esters and Multi‐Class Substances in Dried Blood Spots by LC‐HRMS/MS From a Single Spot for Human Doping Control

Drug Testing and Analysis, EarlyView.
A validated LC‐HRMS/MS method enabled, for the first time, the comprehensive detection of steroid esters and multi‐class menu substances from a single dried blood spot. Following extraction, the resulting extract is split into two aliquots, reducing sample consumption and simplifying the analytical workflow.
