What is CJC-1295 No DAC?
CJC-1295 No DAC is a synthetic 29-amino-acid analogue of growth-hormone-releasing hormone (GHRH), also called Modified GRF 1-29 or Mod GRF 1-29. It carries the molecular formula C152H252N44O42, a molecular weight of 3367.9 g/mol and CAS number 863288-34-0. It is supplied as a lyophilised reference peptide for laboratory research use only.
The "No DAC" designation marks the difference from the DAC version: this variant omits the Drug Affinity Complex modification that prolongs circulating half-life, so it is the short-acting form. Both are studied as ligands at the GHRH receptor. The molecule is frequently referenced alongside the GH-secretagogue ipamorelin in receptor-pharmacology literature, which is an identity and comparison relationship only, not a protocol for any use in humans.
Is CJC-1295 No DAC legal in the UK?
CJC-1295 No DAC is not a controlled drug under the Misuse of Drugs Act 1971, and it is not scheduled. It is supplied strictly as a research chemical for in-vitro and laboratory investigation. It is not a licensed medicine and cannot be sold or supplied for human or veterinary consumption. The purchaser is responsible for compliant handling, storage and disposal under their own institutional and legal obligations. See our research disclaimer for the full terms.
How are identity and quality assured?
Each batch is released only after independent analytical testing. Purity is assessed by HPLC at 99% or higher, and identity is confirmed against the expected mass for C152H252N44O42 (3367.9 g/mol, CAS 863288-34-0). The PubChem record (CID 56841945) carries the canonical chemical identifiers used to verify the material. A certificate of analysis is available for every batch; browse the current set on our certificates of analysis page.
What does the research on CJC-1295 No DAC investigate?
The published literature examines CJC-1295 No DAC as a GHRH-receptor agonist in pre-clinical and in-vitro model systems, including its short-acting pharmacokinetic profile relative to the DAC analogue. Search queries around side effects and benefits sit in this same research area. None of this work establishes a benefit, effect or outcome in humans, and the material is not a licensed medicine. The mechanistic detail and the evidence base are covered in our CJC-1295 No DAC research monograph.
How is CJC-1295 No DAC supplied and reconstituted?
The peptide ships as a lyophilised white to off-white solid. Store the lyophilised vial at -20C, kept dry and protected from light; hold reconstituted material at 2-8C. For bench work it is reconstituted with a solvent such as bacteriostatic water, which Kovalabs stocks as a separate research consumable. CJC-1295 No DAC sits in the GH-axis category alongside related research peptides including CJC-1295 DAC, ipamorelin and sermorelin.

- What is CJC-1295 No DAC?
- CJC-1295 No DAC is a synthetic 29-amino-acid analogue of growth-hormone-releasing hormone (GHRH), also called Modified GRF 1-29 or Mod GRF 1-29. It has the molecular formula C152H252N44O42, a molecular weight of 3367.9 g/mol and CAS number 863288-34-0. It is supplied as a lyophilised reference peptide for laboratory research use only, and is not a licensed medicine.
- What is the difference between CJC-1295 No DAC and CJC-1295 DAC?
- The two share the GHRH analogue backbone. The DAC version carries the Drug Affinity Complex modification that extends circulating half-life, making it the long-acting form, while the No DAC variant (Mod GRF 1-29) omits it and is short-acting. They are studied as distinct research chemicals. The DAC analogue is listed separately as our CJC-1295 DAC product.
- Is CJC-1295 No DAC the same as Mod GRF 1-29?
- Yes. Mod GRF 1-29 and Modified GRF 1-29 are common synonyms for CJC-1295 No DAC. They refer to the same short-acting GHRH analogue with molecular formula C152H252N44O42, CAS 863288-34-0 and PubChem CID 56841945. The names are used interchangeably across the research literature.
- Is CJC-1295 No DAC legal in the UK?
- CJC-1295 No DAC is not a controlled drug under the Misuse of Drugs Act 1971 and is not scheduled. It is supplied only as a research chemical for laboratory and in-vitro investigation. It is not a licensed medicine and cannot be sold for human or veterinary consumption. The purchaser is responsible for lawful, compliant handling under their own obligations.
- Is CJC-1295 No DAC intended for human use?
- No. CJC-1295 No DAC is supplied strictly for laboratory research use only. It is not intended, labelled or sold for human or veterinary use, and no human application is implied. It is a reference compound for non-clinical investigation. Any other use falls outside the terms of supply.
- Has CJC-1295 No DAC been shown to be safe or effective in humans?
- No. The published work on CJC-1295 No DAC is conducted in pre-clinical and in-vitro model systems and investigates its activity at the GHRH receptor. None of this research establishes a benefit, effect, safety profile or outcome in humans. It is not a licensed medicine and no human safety or efficacy claim is made.
- What does the research on CJC-1295 No DAC look at?
- The literature studies CJC-1295 No DAC as a short-acting GHRH-receptor agonist in laboratory and animal model systems, including its pharmacokinetics relative to the DAC analogue. This is receptor-pharmacology research only. The mechanistic and evidence detail is covered in our CJC-1295 No DAC research monograph; nothing there constitutes a human claim.
- Why is CJC-1295 No DAC often mentioned with ipamorelin?
- CJC-1295 No DAC and ipamorelin are frequently referenced together because they act on different parts of the growth-hormone axis: CJC-1295 No DAC is a GHRH analogue and ipamorelin is a GH-secretagogue. This is an identity and comparison relationship in the literature. It is not a protocol or recommendation for any combined use in humans.
- Is all CJC-1295 No DAC the same quality?
- No. Quality varies by supplier and batch. Kovalabs releases each batch only after independent testing, with purity assessed by HPLC at 99% or higher and identity confirmed against the expected mass. A certificate of analysis is available for every batch on our certificates of analysis page, so identity and purity can be verified before use.
- What are the molecular identifiers for CJC-1295 No DAC?
- CJC-1295 No DAC has the molecular formula C152H252N44O42, a molecular weight of 3367.9 g/mol and CAS number 863288-34-0. Its PubChem record is CID 56841945. It is a 29-amino-acid GHRH analogue (Modified GRF 1-29). These identifiers are used to confirm the material against analytical results.
- How is CJC-1295 No DAC supplied?
- CJC-1295 No DAC is supplied as a lyophilised white to off-white solid in a sealed vial. The milligram strength stated on the listing is the quantity of peptide in the vial, a product specification rather than any human dose. It ships from the UK for laboratory research use only.
- How is CJC-1295 No DAC reconstituted and stored?
- For bench work the lyophilised peptide is reconstituted with a solvent such as bacteriostatic water, which Kovalabs stocks separately. Store the lyophilised vial at -20C, kept dry and protected from light. Reconstituted material should be held at 2-8C. These are laboratory handling steps for the research material.
- Is a certificate of analysis available for CJC-1295 No DAC?
- Yes. Every batch of CJC-1295 No DAC is released with a certificate of analysis reporting HPLC purity (99% or higher) and confirmed identity against the expected mass for C152H252N44O42. Current certificates are published on our certificates of analysis page so the material can be verified before laboratory use.
- Is CJC-1295 No DAC a peptide or a steroid?
- CJC-1295 No DAC is a peptide, not a steroid. It is a synthetic 29-amino-acid chain analogous to the first 29 residues of growth-hormone-releasing hormone (Modified GRF 1-29). It is studied as a GHRH-receptor ligand and is supplied as a lyophilised research peptide, not a steroid hormone.
