CJC-1295 nudges the pituitary gland to release growth hormone in a natural, pulse-like pattern. It's often paired with Ipamorelin for balanced, rhythmic GH support.
A deeper look for the curious
For readers who want the full mechanism — feel free to skim.
CJC-1295 is a close copy of GHRH, the hormone the brain uses to tell the pituitary gland to release growth hormone. Giving it mimics that natural signal — producing extra growth hormone pulses without overriding the body's built-in rhythm.
What researchers have observed in studies
Amplifies natural GH pulsatility without disrupting rhythm
Increases circulating IGF-1 in dose-dependent manner
DAC variant extends half-life to ~8 days
GHRH receptor (somatotrophs)
29 amino acid modified GHRH analog
Amino acid chain
