Overview
CJC-1295 (No DAC) — also known as Modified GRF 1-29 or Mod GRF — is a synthetic analogue of Growth Hormone-Releasing Hormone (GHRH) with four amino acid substitutions that confer increased stability and reduced enzymatic degradation compared to the native sequence. Unlike the DAC version, CJC-1295 without DAC has a shorter half-life (~30 minutes), producing more physiologically pulsatile GH release patterns. It is one of the most studied GHRH analogues in growth hormone secretagogue research.
