ts of the recent technical documents from the World Anti-Doping Agency (WADA) considering their minimum required performance levels (MRPL) are fulfilled, and the method was validated for its utilisation [...] initial testing procedure in doping controls. Finally, the approach was applied to authentic post-administration study urine samples (for insulins and gonadorelin) in order to provide proof of principle.

profile of microdosed S-23 and to characterize the elimination pattern. Single and multidose administration studies with 1, 10, and 50 μg of S-23 were conducted, and collected urine samples were analyzed [...] detection of 1 pg/mL. A total of 18 metabolites was detected in human in vivo samples following oral administration of microdosed S-23. Moreover, the study demonstrated that a single dose of 1 μg can be detected

demonstrated its specificity and sensitivity (LOD: 1 ng/mL), and the subsequent analysis of post-administration urine samples showed for the first time that intact (or at least GH receptor binding) somatrogon
