It increases the half-life of acting agents by bioconjugation.[6] CJC-1295 was under investigation for the treatment of lipodystrophy and growth hormone deficiency and reached phase II clinical trials but was discontinued upon the death of one of the trial subjects.[7][8] The attending physician of the trial believed that the most likely explanation for the incident was that the patient had asymptomatic coronary artery disease with plaque rupture and occlusion, and that the occurrence was unrelated to treatment with CJC-1295.[8] In any case, research was terminated nonetheless as a precaution.[8] CJC-1295 has found black market use for bodybuilding purposes, with this, in some countries such as the Netherlands, being an illicit use.[7][9] See also

This technology, which is relatively new in nature, is defined by its ability to take a reactive group and bond it to a peptide (Aslam and Dent). This attachment causes a reaction with a nucleophilic unit; a typically partially molecule that is found within the bloodstream of an animal test subject. This reaction in turn causes a more stable bond to occur. This specific peptide has an especially high attraction to albumin, a globular protein that is soluble in water. This affinity prohibits natural degradation, which in turn increases the peptide’s half-life (Hermanson). Additionally, clinical research performed on animal test subjects has thus far shown that there have been no signs of DPP-IV degradation present when CJC-1295 was introduced (Gonzalez, US Peptide Articles).}} 7. ^1 {{cite journal|last1=Andersen Hartvig|first1=Rune|last2=Bjerre Holm|first2=Niels|last3=Weihe Dalsgaard|first3=Petur|last4=Ask Reitzel|first4=Lotte|last5=Breum Müller|first5=Irene|last6=Linnet|first6=Kristian|title=Identification of peptide and protein doping related drug compounds confiscated in Denmark between 2007-2013|journal=Scandinavian Journal of Forensic Science|volume=20|issue=2|year=2014|issn=2353-0707|doi=10.2478/sjfs-2014-0003}} 8. ^1 2 {{cite web|url=http://www.natap.org/2006/newsUpdates/081106_02.htm|author=ConjuChem|title=Patient Died in Lipodystrophy Drug Study| date=August 2006 }} 9. ^{{cite journal|last1=Henninge|first1=John|last2=Pepaj|first2=Milaim|last3=Hullstein|first3=Ingunn|last4=Hemmersbach|first4=Peter|title=Identification of CJC-1295, a growth-hormone-releasing peptide, in an unknown pharmaceutical preparation|journal=Drug Testing and Analysis|volume=2|issue=11-12|year=2010|pages=647–650|issn=1942-7603|doi=10.1002/dta.233}} External links
