CJC-1295 Whitout DAC

CJC-1295 without DAC, often referred to as Mod GRF 1-29, is a stabilised analogue of growth hormone–releasing hormone (GHRH). It is engineered to resist rapid enzymatic breakdown while maintaining activity at the GHRH receptor, making it a common tool peptide for studying GH-axis physiology. In research, Mod GRF 1-29 is evaluated for its effects on pulsatile growth hormone release patterns and downstream endocrine markers such as IGF-1 signalling activity. Studies commonly examine secretion kinetics, receptor responsiveness, and feedback regulation to characterise how GHRH-pathway stimulation influences measurable hormonal dynamics.
