What is CJC / Ipamorelin?

CJC / Ipamorelin is a two-peptide research blend pairing a synthetic GHRH analogue with a selective pentapeptide growth-hormone secretagogue, supplied as a lyophilised powder. It is supplied strictly for laboratory research use only.

What research area is CJC / Ipamorelin associated with?

Published preclinical laboratory work in this class concerns GHRH and ghrelin (GHS-R1a) receptor signalling chemistry. We supply the material only; we make no representation as to any outcome, effect, or suitability for any purpose.

Is CJC / Ipamorelin approved for human use?

No. CJC / Ipamorelin 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 / Ipamorelin 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 Purity figures are stated per lot - we do not publish a brand-wide specification in place of the actual certificate.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 / Ipamorelin is tested by an outside lab before it goes on sale — not by us. The one shipping now is lot H2XMF1: 99.93% pure by HPLC, tested by Accurate Lab Tests on 29 Jul 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 / Ipamorelin works

A two-peptide research pairing studied for driving growth hormone through two receptors at once.

GHRH receptorCJC-1295

Studied for prompting growth-hormone release via the GHRH receptor.

Ghrelin receptorIpamorelin

Investigated for a clean GHS-R signal that raises GH without spiking cortisol or prolactin.

IGF-1 boostdual pathway

Researched for pushing IGF-1 higher than either peptide reaches alone.

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.

Growth factor boostPreclinical

Growth hormone secretagogues act synergistically with GHRH but through a different receptor — the reason the two classes are studied together.

Directional; exact magnitudes vary by protocol.

Clean signalPreclinical

In pigs, ipamorelin released growth hormone without the ACTH and cortisol rise seen with the older peptides GHRP-6 and GHRP-2, and left prolactin, TSH, FSH and LH unchanged.

Natural rhythmPreclinical

GH-axis research suggests the combination preserves the body's natural pulsatile pattern of growth-hormone release rather than flattening it into a constant level.

Illustrative of a preserved pulsatile rhythm; qualitative report.
