At A Glance
- CJC-1295 No DAC is the common catalogue name for a modified GHRH fragment, often called modified GRF(1–29). It is studied as a relatively short signal that prompts growth-hormone release.
- The No DAC shorthand usually refers to a modified 29-amino-acid GHRH fragment.
- The absence of DAC changes the exposure strategy.
What Is CJC-1295 (NO DAC)?
CJC-1295 No DAC is the common catalogue name for a modified GHRH fragment, often called modified GRF(1–29). It is studied as a relatively short signal that prompts growth-hormone release.
The peptide activates GHRH receptors in the pituitary. Changes to the amino-acid sequence help resist some breakdown, but it lacks the albumin-binding feature used by the With DAC version.
Why Does The Name Get Confusing?
CJC-1295 became a familiar shorthand, and the No DAC label is often used more loosely than the chemistry. Knowing that it generally means modified GRF makes the literature easier to navigate: the exact sequence is more informative than the shortened name.
How Is No DAC Different From With DAC?
With DAC attaches to albumin, a protein in blood, to prolong exposure. No DAC does not use that strategy. Both connect to the GHRH pathway, but the longer-lasting results reported for albumin-binding CJC-1295 belong to that version.

| Study or context | What was explored | What it tells us | Useful context |
|---|---|---|---|
| Molecular identity | Modified GRF(1–29) | The No DAC shorthand usually refers to a modified 29-amino-acid GHRH fragment. | The sequence identifies which material was studied. |
| Timing | Shorter signal versus albumin binding | The absence of DAC changes the exposure strategy. | The linked albumin-conjugate paper explains the contrast; it is not direct evidence for the No DAC product. |
