CJC-1295

aka CJC-1295 with DAC

Growth Hormone Secretagogues

Mechanism

CJC-1295 is a synthetic tetrasubstituted analog of growth hormone-releasing hormone (GHRH 1-29) originally developed by ConjuChem. The name historically refers to the DAC-modified (Drug Affinity Complex) form that covalently binds serum albumin, producing a 6–8 day half-life; a separate no-DAC form (also called Modified GRF 1-29) shares the same tetrasubstituted backbone but lacks the albumin-linking maleimidopropionyl-lysine and has a half-life of roughly 30 minutes. Not FDA-approved in any form; ConjuChem halted Phase 2 development around 2007 after a patient death in an HIV-lipodystrophy trial (ultimately judged by investigators to be unrelated to the drug, but development was terminated regardless).
