CJC-1295 with DAC
CJC-1295 with DAC (Drug Affinity Complex) is a synthetic analog of growth hormone-releasing hormone (GHRH) modified with a tetrasubstituted C-terminus and a lysine-linked Drug Affinity Complex for extended half-life. Preclinical studies in animal models indicate that CJC-1295 with DAC stimulates sustained pulsatile release of endogenous growth hormone (GH) and elevates IGF-1 levels over prolonged periods, supporting research into metabolic regulation, body composition, and tissue repair.[1][2]
Key Research Areas
- Growth Hormone & IGF-1 Elevation – In porcine and rodent models, CJC-1295 with DAC has been shown to induce prolonged GH release and significantly increase circulating IGF-1 concentrations for up to several days after administration.[1][3]
- Metabolic Effects & Body Composition – Preclinical research demonstrates enhanced lipolysis, improved nitrogen balance, and potential changes in lean mass and fat distribution in animal models of growth hormone axis modulation.[2][4]
- Recovery & Tissue Maintenance Pathways – Studies suggest sustained GH/IGF-1 signaling may support protein synthesis, collagen production, and recovery processes in models involving muscle and connective tissue.[5][6]
