CJC-1295
syntheticAlso known as: CJC 1295, CJC1295
Mechanism
CJC-1295 is a synthetic growth hormone releasing hormone (GHRH) analog that stimulates the pituitary gland to release growth hormone. Unlike natural GHRH which is quickly broken down in the body, CJC-1295 is modified to resist degradation, allowing it to work for days rather than minutes.
Technical detail
CJC-1295 is a 29-amino acid synthetic analog of GHRH (1-29) with four amino acid substitutions that increase binding affinity and resistance to DPP-IV enzymatic cleavage. It binds to GHRH receptors on somatotroph cells in the anterior pituitary, activating the cAMP-PKA pathway to stimulate GH synthesis and secretion. The drug has an extended half-life of 5.8-8.1 days due to bioconjugation with serum albumin via a reactive maleimide group.
