Detection and in vitro metabolism of the confiscated peptides BPC 157 and MGF R23H

Cox HD, Miller GD, Eichner D · Drug Testing and Analysis

BPC 157 was confirmed in seized vials and forms a stable plasma metabolite detectable in urine; the validated extraction method reaches a 0.1 ng/mL limit of detection with the peptide stable in urine for at least four days, so use is traceable in anti-doping testing.

Population

Peptides identified in confiscated vials; plasma and urine metabolism experiments

Limitations

Analytical rather than clinical; documents what was in a particular set of confiscated vials, not the composition of the wider gray market.
