Ipamorelin is a synthetic peptide made of five amino acids (a pentapeptide). It is supplied lyophilised as a research compound for in vitro laboratory study only.

What Ipamorelin is

Ipamorelin is a short, fully synthetic pentapeptide with a defined five-amino-acid sequence. In the research literature it is classed as a growth-hormone secretagogue — a group of compounds studied for their interaction with the ghrelin / GH-secretagogue receptor.

Its sequence is confirmed by mass spectrometry and its purity measured by HPLC, so each batch can be reported on an independent Certificate of Analysis.

Where Ipamorelin appears in research

In the research literature, Ipamorelin is studied in growth-hormone-secretagogue research models. This describes the research domain in which the compound appears, not a claim of any effect. Ipamorelin is not a medicine, supplement or cosmetic, and is not approved for human or veterinary use.

How Ipamorelin should be tested

Quality is a matter of evidence, not the label. A credible supplier tests every batch at an independent laboratory: HPLC measures purity as a percentage (commonly to a ≥99% benchmark), and mass spectrometry confirms the compound’s identity.

The result should be a batch-specific Certificate of Analysis you can verify at source. Learn how to read a COA, or see BioHack London’s independent Ipamorelin reports.

Storage, handling and reconstitution

Lyophilised (freeze-dried) Ipamorelin is generally kept cool, dry and out of light. Reconstitution — dissolving it in a suitable solvent such as bacteriostatic water — is done immediately before laboratory use, and the reconstituted solution is typically refrigerated and used within a limited period.

Our reconstitution calculator helps work out solvent volumes, and bacteriostatic water is available in the range.

Ipamorelin: frequently asked questions

What is Ipamorelin?

Ipamorelin is a synthetic five-amino-acid peptide (a pentapeptide) classed in the research literature as a growth-hormone secretagogue. It is supplied as a lyophilised research compound for in vitro laboratory research use only.

What is a growth-hormone secretagogue?

It is a research term for a class of compounds studied for their interaction with the ghrelin / growth-hormone-secretagogue receptor. It describes the research domain Ipamorelin is studied in — not an effect.

How is Ipamorelin tested?

A credible supplier tests each batch at an independent laboratory — HPLC for purity (commonly to a ≥99% benchmark) and mass spectrometry to confirm identity — and publishes a batch-specific Certificate of Analysis you can verify at source.

Is Ipamorelin for human use?

No. Ipamorelin is supplied strictly for in vitro laboratory research. It is not for human or animal consumption and is not intended to diagnose, treat, cure or prevent any condition. Purchasers must be 18 or over.
