What is CJC-1295 with DAC?

CJC-1295 with DAC is a synthetic growth-hormone-releasing-hormone (GHRH) analogue carrying a Drug Affinity Complex that binds serum albumin, supplied as a lyophilised powder. It is supplied strictly for laboratory research use only.

What research area is CJC-1295 with DAC associated with?

Published preclinical laboratory work in this class concerns GHRH receptor signalling and peptide half-life chemistry. We supply the material only; we make no representation as to any outcome, effect, or suitability for any purpose.

Is CJC-1295 with DAC approved for human use?

No. CJC-1295 with DAC is not a drug, supplement, food, cosmetic, or medical device, and has no approved human or veterinary indication. It is sold strictly for in-vitro laboratory research use by qualified professionals.

What purity is CJC-1295 with DAC supplied at, and how is it verified?

Each lot is assayed by HPLC and ships with its own lot-specific Certificate of Analysis, published in our COA registry. Purity figures are stated per lot - we do not publish a brand-wide specification in place of the actual certificate.

Proof, not promises. Every batch, tested by an outside lab.

Every batch of CJC-1295 with DAC is tested by an outside lab before it goes on sale — not by us. The one shipping now is lot CD5-WM2607-001: 99.33% pure by HPLC, tested by Accurate Lab Tests on 31 Aug 2026. The signed report is right here. Purity is the number the lab measured, never “at least 99” — and a batch that misses its spec never ships.

How CJC-1295 with DAC works

A long-acting growth-hormone-releasing research peptide studied across the GH–IGF-1 axis.

GHRH receptoragonist

Studied for binding the growth-hormone-releasing-hormone receptor to prompt GH secretion.

Sustained GHDAC-extended

Investigated for holding growth-hormone levels elevated over multi-day windows via albumin binding.

IGF-1 axisdownstream marker

Researched for the downstream rise in IGF-1 across the GH axis.

How long it lastsPreclinical

5.8–8.1 days

In healthy adults, the estimated half-life of CJC-1295 was 5.8 to 8.1 days — days, where natural GHRH lasts minutes.

vs minutes for unmodified peptide

Natural GHRH~minutes

CJC-1295 with DAC5.8–8.1 days

Estimated half-life in healthy adults.

Steady hormone levelsPreclinical

After a single injection in healthy adults, mean growth hormone rose 2- to 10-fold for six days or more, and IGF-1 rose 1.5- to 3-fold for nine to eleven days.

CJC-1295 with DACShort-acting peptide

Directional; the sustained arm holds elevation between pulses.

Journal of Clinical Endocrinology & Metabolism, 2006 · healthy adults

Why it lastsPreclinical

Reviewers attribute the long duration to the Drug Affinity Complex (DAC), which binds serum albumin to slow the body's clearance of the peptide versus the unmodified form.
