CJC-1295 vs Sermorelin: GHRH Analog Comparison

CJC-1295 is a synthetic GHRH (growth hormone-releasing hormone) analog available in two forms: with DAC (Drug Affinity Complex) providing an extended 8-day half-life for sustained GH elevation, and without DAC (mod-GRF 1-29) for pulsatile GH release. Sermoreli

  • CJC-1295 is a synthetic GHRH (growth hormone-releasing hormone) analog available in two forms: with DAC (Drug Affinity Complex) providing an extended 8-day half-life for sustained GH elevation, and without DAC (mod-GRF 1-29) for pulsatile GH release. Sermorelin is the first 29 amino acids of natural GHRH, previously FDA-approved for pediatric growth hormone deficiency, with the most human clinical data among GHRH analogs. Both stimulate endogenous GH production through the GHRH receptor but differ significantly in half-life, dosing frequency, and GH release patterns.
