CJC-1295 (no DAC) is a synthetic analogue of growth hormone releasing hormone (GHRH), also referred to as modified GRF 1-29. It binds to GHRH receptors in the anterior pituitary gland to stimulate the synthesis and secretion of growth hormone. The no DAC (Drug Affinity Complex) version lacks the maleimidopropionic acid linker present in CJC-1295 with DAC, resulting in a shorter half-life that produces more pulsatile GH release patterns. Researchers consider this pulsatile pattern more physiologically similar to natural endogenous GH secretion, making CJC-1295 no DAC particularly valuable for studies requiring physiological GH release kinetics. The compound is frequently studied in combination with Ipamorelin, a selective GHS-R1a agonist, for synergistic effects through complementary receptor pathways — CJC-1295 stimulating GH release via the GHRH receptor while Ipamorelin acts at the ghrelin receptor. This dual-pathway approach produces amplified GH pulses and has become a standard research protocol in growth hormone biology. Studies have examined CJC-1295's effects on plasma GH levels, IGF-1 production, body composition, and sleep-related GH secretion patterns.
