CJC-1295 with Drug Affinity Complex
By applying the Drug Affinity Complex (DAC) technology to GRF, the peptide selectively and covalently binds to circulating albumin after subcutaneous (SC) administration, thus prolonging its half-life. These substitutions are key in increasing the overall half life of CJC-1295 but there lies an even greater reason as to why the half life has been extended from ~7 minutes to greater than 7 days..
CJC-1295 is a Long acting GHRH analog. Growth-hormone-releasing hormone (GHRH), also known as growth-hormone-releasing factor (GRF or GHRF) or somatocrinin, is a 44-amino acid peptide hormone produced in the hypothalamus by the arcuate nucleus. GHRH stimulates growth hormone (GH) secretion from the pituitary. GHRH is released in a pulsatile manner, stimulating pulsatile release of GH respectively. This substance also promotes slow wave sleep. The active portion of this GRF or GHRH peptide can be found as a 29 amino acid long peptide and is appropriately named GHRH1-29. This pulsatile release of various peptides is due to the negative feedback loop that is part of the hGH axis and controls the amount of hGH that your body produces to keep it in a homeostatic environment.
