CJC-1295, also known as DAC:GRF (short for drug affinity complex:growth hormone-releasing factor), is a synthetic analogue of growth hormone-releasing hormone (GHRH) (also known as growth hormone-releasing factor (GRF)) and a growth hormone secretagogue (GHS) which was developed by ConjuChem Biotechnologies.[1][2][3] It is a modified form of GHRH (1-29) with improved pharmacokinetics, especially in regard to half-life.[1][2][3][4]
Effects
CJC-1295 markedly increases plasma growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels in both animals and humans.[1][2][3][5] With a single injection, in human subjects, CJC-1295 increases plasma GH levels by 2- to 10-fold for 6 days or longer and plasma IGF-1 levels by 0.5- to 3-fold for 9 to 11 days.[3] The drug has an estimated half-life of about 6 to 8 days in humans.[3] With multiple doses of CJC-1295, IGF-1 levels were found to remain elevated in humans for up to 28 days.[3]
CJC-1295 has been shown to extend the half-life and bioavailability of growth-hormone-releasing hormone 1-29 and stimulate insulin-like growth factor 1 secretion. It increases the half-life of acting agents by bioconjugation.[6] The extended half-life is achieved through the addition of a drug affinity complex (DAC) that binds to albumin, thus prolonging the peptide's presence in the bloodstream.[7][8][9] It is primarily used for its potential to stimulate the release of growth hormone (GH) from the pituitary gland.[10]
Risks
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.[11][12] 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.[12] Research was terminated nonetheless as a precaution.[12] CJC-1295 has found grey market use for bodybuilding purposes, with this, in some countries such as the Netherlands, being an illicit use.[11][13]

The reason why CJC1295 possesses the ability to lengthen the half-life within the active agent has to do with the scientific process known as bioconjugation. 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).
