CJC-1295 (No DAC) is a synthetic research peptide that functions as a growth hormone–releasing hormone (GHRH) analog. It has been studied in laboratory settings for its ability to stimulate growth hormone (GH) secretion and insulin-like growth factor 1 (IGF-1) production. The “No DAC” designation means this version does not include the drug affinity complex (DAC) modification, resulting in a shorter half-life and different research applications compared to CJC-1295 with DAC. CJC-1295 (No DAC) continues to generate interest in endocrine and metabolic research models.

Area of Interest

Research into CJC-1295 (No DAC) has focused on several areas:

• Growth Hormone Studies: Evaluated for its ability to stimulate pulsatile GH release without extending activity through DAC binding.
• IGF-1 Modulation: Investigated for its influence on circulating IGF-1 levels in preclinical models.
• Endocrine Regulation: Studied as part of broader research into pituitary–hypothalamic signaling pathways.
• Comparative Research: Compared with CJC-1295 with DAC to understand differences in half-life, receptor binding, and activity windows.

Together, these areas highlight CJC-1295 (No DAC) as a valuable tool for understanding growth hormone regulation in research environments.
