Overview

What it is.

CJC-1295 with DAC adds a Drug Affinity Complex to the base GHRH analog, extending its circulating half-life well beyond CJC-1295 without DAC. It is studied separately from the no-DAC version for research into sustained, rather than pulsatile, GH-axis signaling.

Research Areas

  • Studied for its extended half-life relative to CJC-1295 without DAC
  • Studied for its potential role in sustained growth-hormone-axis signaling research
  • Studied for its potential role in body-composition research alongside diet and exercise variables

Research Deep-Dive

How it works.

CJC-1295 with DAC is the base GHRH analog CJC-1295 modified with a Drug Affinity Complex (DAC), a chemical tag that binds circulating albumin and dramatically extends the molecule's half-life compared with the no-DAC version also sold here.

Like unmodified CJC-1295, it's studied for engaging the GHRH receptor on the pituitary gland — but the DAC modification's albumin-binding extends its circulating presence from hours to days, shifting the research question from pulsatile GH release toward sustained GH-axis signaling.

  • Studied for sustained growth-hormone-axis signaling research
  • Studied for body-composition research alongside diet and exercise variables

The Evidence

Pharmacokinetic research

The DAC modification's albumin-binding and half-life-extension effect is well documented in pharmacokinetic literature; downstream body-composition outcomes are studied far less rigorously than the pharmacokinetics themselves.

Comparative GHRH-analog research

Most evidence comparing DAC and no-DAC signaling patterns comes from smaller mechanistic studies rather than large controlled trials.

Questions

CJC-1295 with DAC FAQ

What is CJC-1295 with DAC studied for?+

CJC-1295 with DAC is studied for its extended half-life relative to the no-DAC version and its potential role in sustained growth-hormone-axis and body-composition-related signaling research.

How is CJC-1295 with DAC different from the CJC-1295 (no DAC) product on this site?+

The DAC modification extends circulating half-life substantially. Researchers studying sustained GH-axis signaling use the DAC version; researchers studying pulsatile signaling closer to natural GHRH release patterns tend to use the no-DAC version.

What does the DAC modification actually do chemically?+

Drug Affinity Complex (DAC) is a chemical modification that binds circulating albumin in the bloodstream, which is what extends the peptide's half-life well beyond the no-DAC version.

How should CJC-1295 with DAC be handled and stored?+

It ships as a lyophilized powder. Reconstitute with bacteriostatic water and refrigerate at 2–8°C after mixing — good for roughly 4–6 weeks refrigerated, or up to 24 months unreconstituted in a cool, dry place.
