Ipamorelin: Peptide Profile

Sequence, molecular data, research status and testing standards for Ipamorelin, written for Canadian researchers.

What Is Ipamorelin?

Ipamorelin is a synthetic five-amino-acid peptide that activates the ghrelin (growth hormone secretagogue) receptor. It was designed to prompt growth hormone release from the pituitary gland while having little effect on other hormones such as cortisol and prolactin in early studies.

What the Research Says About Ipamorelin

Ipamorelin was developed in the 1990s and studied in early clinical trials, including for recovery of bowel function after surgery. It did not go on to become an approved drug. It is most often discussed as a selective growth hormone secretagogue and is frequently paired in research discussions with a GHRH analogue such as CJC-1295 (no DAC).

How Ipamorelin Works, in Plain English

What it isA small lab-made copy of the hunger hormone ghrelin.

The plain-English storyA small ghrelin lookalike, described as more targeted than its louder cousins. It tells the master gland to release growth hormone. It was tried in early studies, including for recovery after bowel surgery, but it never became a medicine, and it is banned in sport.

How it works, in simple termsIt tells the body's master gland to release growth hormone, and is described as more targeted than similar molecules.

What the science really showsEarly trials looked at recovery after bowel surgery. It never became an approved medicine.

What you may hear onlineVideos often describe it as a safe growth hormone booster.

The straight storyNo peptide of this kind has been proven safe for general use. It is not approved and is banned in sport.

Where it stands in CanadaNot an approved medicine in Canada, so nobody can legally sell it to you as one. Also banned in sport.

What to Check Before Trusting Any Research Peptide

  • A lot-matched COA from an independent laboratory
  • HPLC purity and mass spectrometry results, not just a purity number
  • Clear research-use labelling and no medical claims
  • Banned in sport: ipamorelin is on the WADA Prohibited List (S2)

Is Ipamorelin Legal in Canada?

Ipamorelin is not authorized by Health Canada as a drug and has no Drug Identification Number (DIN), so it cannot legally be sold for human or animal use in Canada. In Canada it can only be sold as a research chemical for in-vitro laboratory use. This is general information, not legal advice. Read how peptides are regulated in Canada.

Ipamorelin FAQs

What is Ipamorelin?

Ipamorelin is a synthetic five-amino-acid peptide that activates the ghrelin (growth hormone secretagogue) receptor. It was designed to prompt growth hormone release from the pituitary gland while having little effect on other hormones such as cortisol and prolactin in early studies. It is also known as NNC 26-0161.

Where can I buy Ipamorelin in Canada?

This page is for information only. Ipamorelin is not authorized for human or animal use in Canada, and products sold online without a verified third-party Certificate of Analysis cannot be trusted. If you are a researcher, see our guide to reading a COA and our supplier checklist.

How is ipamorelin different from GHRP-2, GHRP-6 and CJC-1295?

Ipamorelin, GHRP-2 and GHRP-6 are growth hormone secretagogues that act on the ghrelin receptor. Ipamorelin is described as more selective. CJC-1295 is different: it is a GHRH analogue that acts on a separate receptor, so the two are often discussed together.

Is Ipamorelin banned in sport?

Yes. Ipamorelin is on the World Anti-Doping Agency (WADA) Prohibited List: Prohibited: S2 (growth hormone-releasing peptides and secretagogues).
