CJC-1295 no DAC: chemistry, literature and regulatory status

Written by the Peptency editorial teamLast reviewed 6 studies checked in PubMed on 5 October 2026

Research-use information. This page summarises published literature and regulator records. It is not guidance for use, not medical advice, and not a statement that any material is suitable for use in people or animals.

What is CJC-1295 no DAC?

CJC-1295 without DAC, also written modified GRF (1-29), is a 29-residue amidated analogue of growth hormone-releasing hormone with four amino acid substitutions relative to sermorelin. Most published pharmacology concerns the albumin-binding (DAC) form, not this unconjugated peptide. It is supplied here as a research material for laboratory use only.

How does the literature describe the mechanism of CJC-1295 no DAC?

  • Growth hormone-releasing hormone acts at a pituitary G-protein-coupled receptor that was cloned in 1992; reviews describe its signal transduction and physiology.[6],[5]
  • Albumin bioconjugates of GRF(1-29) were made and tested for stability against peptidase degradation and for activity at the GRF receptor.[4]

Receptor and pathway background: Growth hormone-releasing hormone receptor.

PubMed returns 34 records for the search terms published on the method page (10 of them with a review publication type, 2 with a clinical-trial publication type), checked 5 October 2026. ClinicalTrials.gov lists 1 registered studies whose intervention matches the name (1 interventional), checked 5 October 2026.

  • Two clinical papers on CJC-1295 describe the albumin-binding form, whose half-life is reported as 8 days; they do not study the unconjugated peptide listed here.[3],[2]
  • A review of methods to detect synthetic GHRH analogues notes that these peptides are prohibited by the World Anti-Doping Agency.[1]

Studies are listed by what they measured. Papers whose titles state an amount or schedule, or describe a clinical outcome of an approved medicine, are not listed. This is a wording rule, not a quality filter; see the method page.
