“CJC-1295” Is One of the Most Confusing Names in Peptide Research
Search for CJC-1295 peptide and you may find two very different materials presented under nearly the same name.
One contains a Drug Affinity Complex.
The other does not.
For professional laboratories, that is not a small naming detail.
It is a molecular identity issue.
CJC-1295 No DAC, commonly called Modified GRF 1-29 or Mod GRF 1-29, is a synthetic GHRH-related research peptide that does not contain the DAC modification associated with long-acting CJC-1295.
That distinction should be verified before any research material is purchased.
What Is CJC-1295 No DAC?
CJC-1295 No DAC is a modified 29-residue GHRH-related peptide used in laboratory research involving:
- GHRH receptor biology;
- peptide characterization;
- structure-function research;
- analytical method development;
- peptide stability studies;
- biochemical signaling research.
The terms CJC-1295 Without DAC, Modified GRF 1-29 and Mod GRF 1-29 are commonly used for the same research material.
However, it should not be treated as chemically identical to CJC-1295 with DAC.
CJC-1295 No DAC vs CJC-1295 With DAC
This is the distinction that many search results fail to explain clearly.
The DAC version contains an additional albumin-binding chemical modification designed to alter the molecule’s pharmacokinetic behavior.
The No-DAC form does not.
That difference changes measurable characteristics such as molecular mass and chromatographic behavior.
For analytical research, this means a COA for one variant cannot simply be assumed to describe the other.
Same keyword family does not mean same molecule.
What Does the Research Actually Support?
Published human research on classical long-acting CJC-1295 has demonstrated measurable changes in GH and IGF-1 signaling.
But professional scientific interpretation requires an important qualification:
Those well-known human trials studied DAC-containing CJC-1295.
They should not automatically be cited as direct clinical evidence for CJC-1295 No DAC / Modified GRF 1-29.
That evidence gap is especially important because online discussions frequently make broad claims about:
- recovery;
- muscle growth;
- fat loss;
- sleep;
- anti-aging.
Many of those claims go beyond the direct evidence available for the No-DAC material.
For responsible research content, mechanism and clinical outcome should remain separate.
The Bigger Procurement Question: Which Molecule Is Actually in the Vial?
Because naming is inconsistent across the peptide market, professional researchers should evaluate more than a product title.
When selecting a CJC-1295 No DAC supplier, useful questions include:
- Is the product explicitly identified as No DAC / Modified GRF 1-29?
- Is the molecular formula stated?
- Is molecular weight consistent with the claimed material?
- Is HPLC purity documented?
- Is mass-spectrometry data available?
- Does the COA correspond to the actual batch?
- Are SDS and specifications available?
- Can repeat batches be supplied consistently?
This is where analytical documentation becomes more valuable than marketing terminology.

Conclusion
CJC-1295 No DAC demonstrates an important principle in peptide sourcing:
A familiar product name does not guarantee molecular clarity.
When two structurally different research materials circulate under closely related names, serious buyers should verify:
identity, molecular mass, HPLC purity, MS data and batch-specific documentation.
For research procurement, the most important question is not simply:
“Is this CJC-1295?”
It is:
“Which CJC-1295—and can the analytical data prove it?”
