CJC-1295 without DAC, frequently referred to as Modified GRF (1-29) or Mod GRF 1-29, is a synthetic analog of growth hormone-releasing hormone (GHRH). It consists of the first 29 amino acids of GHRH with four amino acid substitutions that improve its resistance to enzymatic degradation. The "without DAC" distinction is important because the version with Drug Affinity Complex has a significantly different pharmacokinetic profile.
This peptide has been widely used in research investigating the hypothalamic-pituitary-growth hormone axis. Because it mimics the pulsatile release pattern of natural GHRH more closely than the DAC version, some researchers prefer it for studies where physiological relevance is a priority. Published literature includes work on GH secretion patterns, IGF-1 responses, and synergistic effects when combined with GH secretagogues like ipamorelin or GHRP-6.
