Modified GRF 1-29
Full name: Mod GRF 1-29 / CJC-1295 without DAC
A GHRH analogue spanning amino acids 1–29 of native GHRH, with four amino acid substitutions to increase potency and resistance to enzymatic degradation. Also referred to as CJC-1295 without DAC. Half-life of approximately 30 minutes. Used by researchers who prefer pulsatile GH release patterns over the continuous elevation produced by CJC-1295 DAC.
