CJC-1295 No DAC
Growth Hormone-Releasing Hormone Analog
Your pituitary waits for a signal before it releases growth hormone. CJC-1295 No DAC is a synthetic version of that signal, rebuilt to survive a little longer.
The short version
What CJC-1295 No DAC actually is
The signal itself is 29 amino acids long, and the modifications exist so enzymes do not break the copy down as quickly. The No DAC part matters more than it sounds. Without the drug affinity complex the whole thing is short acting, which makes it its own research subject, studied separately from the longer acting DAC version.

The mechanism
How CJC-1295 No DAC Works
Three letters change everything here. No DAC means short acting, and that makes it a different compound to study.
It does not supply growth hormone. It talks to the receptor that asks for it. CJC-1295 No DAC binds the same pituitary receptor the body’s own GHRH uses, which means research describes it as working inside the existing feedback loop rather than overriding it. Strip off the drug affinity complex and the whole thing becomes far shorter acting, which is exactly why the No DAC version gets studied on its own terms.
Where the science stands
Key Research Areas
- 01
Talking to the pituitary
It binds the same receptor your own signal uses. That means research treats it as working inside the existing feedback loop rather than overriding it, which is a meaningfully different thing to study than supplying the hormone itself.
- 02
Why No DAC changes everything
With the drug affinity complex attached, levels stay elevated for days. Without it, the effect is short and follows the body’s own rhythm. Two very different research subjects wearing almost the same name.
- 03
Staying intact
The tweaks to the natural sequence exist for one reason. Enzymes chew through the unmodified version fast, and the modified one lasts long enough to study.
- 04
The performance question
Most current interest sits in what happens when you nudge the growth hormone axis at all, which is also why this compound turns up throughout anti-doping literature.
The evidence
What the Research Actually Did
A 2026 review mapping the peptides that act on the growth hormone axis, what the clinical evidence supports, and where the gap sits between that evidence and what people actually believe.

We pulled this together from published work and linked every source, so you never have to take our word for it. Nothing here is a claim about what these compounds do. We would rather you read the sources than trust the summary.

Common questions
Questions People Ask
What is CJC-1295 No DAC?
A synthetic 29 amino acid version of the signal that tells the pituitary to release growth hormone, modified so enzymes do not break it down as quickly. Sold for research purposes only.
What is the difference between CJC-1295 with and without DAC?
DAC stands for drug affinity complex, an addition that keeps the compound circulating for days. Without it, the effect is short and follows the body’s own rhythm. They behave differently enough that research treats them as separate subjects, and most published human data used the DAC form.
Is Modified GRF 1-29 the same thing?
Yes. Modified GRF 1-29, Mod GRF 1-29 and CJC-1295 No DAC all refer to the same compound. The naming is inconsistent across suppliers and literature, which is a common source of confusion.
What does >99% purity actually mean?
More than 99% of the vial contents is the peptide itself rather than fragments or synthesis byproducts, verified by HPLC.
How should it be stored?
Sealed, at 6°C or below, away from heat, light and moisture. It ships as a lyophilized powder, which is the stable form.
