Identification of CJC-1295, a growth-hormone-releasing peptide, in an unknown pharmaceutical preparation.
Editor's note
A forensic identification report, not a study of drug effects. At the request of Norwegian police and customs, analysts used high-resolution LC-MS/MS to characterise a seized, unlabelled pharmaceutical preparation and determined its 29-amino-acid, C-terminally amidated sequence matched CJC-1295. The paper's significance is regulatory and public-safety: it documents that illicitly manufactured CJC-1295 was circulating in 2009, was available before completing clinical trials, and was reaching the bodybuilding community. It classifies CJC-1295 as a WADA-prohibited substance. There is no pharmacology, dosing, or safety data here. For readers, the broader context is the important part: grey-market peptides identified in seizures come with no guarantee of identity, purity, or sterility — a real hazard that this kind of forensic work exists to surface. The compound's actual human evidence remains limited to small Phase II pharmacokinetic and pharmacodynamic trials.
Plain-language abstract
This paper reports how analysts identified an unknown, unlabelled injectable product suspected of containing a peptide drug. Some peptide drugs are made illegally and sold to the public before they have finished — or even started — clinical trials. Norwegian police and customs regularly send such seized preparations for analysis. In 2009, one unknown product was examined using a precise laboratory technique (liquid chromatography combined with high-resolution tandem mass spectrometry). The analysis showed it contained a peptide made of 29 amino acids with a specific chemical cap at one end, and the deduced sequence matched a substance sold under the name CJC-1295. CJC-1295 triggers the release of growth hormone, which makes it a prohibited substance in sport under the World Anti-Doping Agency's rules. The authors note it has potential performance-enhancing effects, is easy to obtain, and appears to be used within the bodybuilding community. The study was a one-off forensic identification; it does not measure the drug's effects, doses, or safety.
