Description
Ipamorelin research peptide
Ipamorelin is a synthetic pentapeptide that acts as an agonist of the growth hormone secretagogue receptor (GHS-R1a), also known as the ghrelin receptor. It belongs to the growth hormone releasing peptide (GHRP) class and is studied in vitro in research on receptor binding, selectivity and growth hormone signalling pathways.
Supplied as a lyophilised powder in a 5mg vial. Ipamorelin is not a licensed medicine in the UK. We supply it strictly as a research reagent.

Frequently asked questions
What is ipamorelin?
Ipamorelin is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) that acts as an agonist of the ghrelin receptor (GHS-R1a). It belongs to the growth hormone secretagogue class and is studied in vitro in receptor and signalling research.
Is ipamorelin a GHRH peptide?
No. Ipamorelin is a growth hormone secretagogue that acts on the ghrelin receptor (GHS-R1a). GHRH analogues act on a different receptor, the GHRH receptor. Researchers often study the two classes side by side because they act through separate pathways.
What makes ipamorelin different from other GHRPs?
In published receptor studies, ipamorelin has been described as more selective than earlier secretagogues such as GHRP-6, with less activity on other hormone pathways in the models tested. This selectivity is one of the main reasons it is used as a reference compound in laboratory research.
What is the ipamorelin sequence?
The sequence is Aib-His-D-2-Nal-D-Phe-Lys-NH2, where Aib is 2-aminoisobutyric acid and D-2-Nal is D-2-naphthylalanine. Its molecular formula is C38H49N9O5, with a molecular weight of about 711.9 g/mol.
What purity is your ipamorelin?
Every batch is purity tested by Janoshik, an independent laboratory, using HPLC before it is released for sale.
How should ipamorelin be stored?
Store the lyophilised powder sealed at −20 °C, protected from light and moisture. Allow the vial to reach room temperature before opening. Stability in solution should be validated within your own laboratory protocol.
Do you ship ipamorelin from the UK?
Yes. Orders placed before 3PM UK time, Monday to Friday, are normally dispatched the same day by Royal Mail Tracked 24. See our Shipping Policy.
Do you provide dosing or usage advice?
No. Ipamorelin is supplied for in vitro laboratory research only. We do not provide dosage, administration or medical advice of any kind.
Research use only. This product is supplied strictly for in vitro laboratory research. It is not for human or animal use, and not for diagnostic or therapeutic purposes. By purchasing, you agree to our Research Use Disclaimer.
