What is CJC-1295 without DAC?

CJC-1295 without DAC (modified GRF 1-29) is a synthetic growth-hormone-releasing-hormone (GHRH) analogue without the albumin-binding complex, supplied as a lyophilised powder. It is supplied strictly for laboratory research use only.

What research area is CJC-1295 without DAC associated with?

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

Is CJC-1295 without DAC approved for human use?

No. CJC-1295 without 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 without 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 Purity figures are stated per lot - we do not publish a brand-wide specification in place of the actual certificate.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 without DAC is tested by an outside lab before it goes on sale — not by us. The one shipping now is lot J3SPEC: 99.72% pure by HPLC, tested by Freedom Diagnostics on 15 May 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 without DAC works

A short-acting GHRH analogue studied for prompting growth hormone in natural pulses.

GHRH receptoragonist

Studied for binding the GHRH receptor to trigger a burst of growth-hormone release.

Pulsatile GHshort half-life

Investigated for a quick-firing profile that mimics the body's natural pulse-like GH rhythm.

IGF-1 markerdownstream

Researched for the accompanying rise in the downstream marker IGF-1.

What the studies found

Published findings on this compound, each linked to its source. Animal and lab results are context, not claims about this product.

Release rhythmPreclinical

In study models, the short half-life of CJC-1295 without DAC preserved the body's natural pulse-like GH release, whereas extended-release DAC forms tended to flatten that rhythm into a steady flood.

vs flat release with DAC

Frontiers in Endocrinology 2026 · review

Without DAC (pulsatile)pulses preserved

With DAC (extended)rhythm flattened

Directional finding from a review — relative heights, not measured magnitudes.

Growth hormonePreclinical

In research models, administration was followed by a rise in growth hormone, timed with the natural overnight GH window rather than a constant elevation.

vs baseline

Directional — the review reports a rise but no precise magnitude.

Frontiers in Endocrinology 2026 · review

IGF-1 markerPreclinical

In the same models, IGF-1 — a downstream marker that follows GH release — also rose after dosing, consistent with activation of the GH–IGF-1 axis.
