CJC-1295 (No DAC)
Short-acting GHRH analogue (Mod GRF 1-29) studied for pulsatile growth-hormone release.
CJC-1295 without DAC — often searched as Modified GRF 1-29 — is a cornerstone of growth-hormone research and one of the most studied GH-pulse peptides in the literature. It is a growth-hormone-releasing-hormone (GHRH) analogue that prompts the pituitary to release GH in the short, natural pulses the body normally uses. Dropping the Drug Affinity Complex (DAC) gives it a shorter half-life, which researchers study specifically for tighter, more physiological pulse patterns.
It is most often studied side by side with Ipamorelin, since the two reach growth-hormone release through complementary pathways.
