Ipamorelin Overview
Ipamorelin is a selective synthetic pentapeptide growth-hormone secretagogue (sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂). It is a selective agonist of the ghrelin receptor (GHS-R1a) with a published profile that distinguishes it from earlier-generation GHRPs by its lack of significant ACTH and cortisol stimulation in receptor selectivity studies.
History
Developed by Novo Nordisk in the 1990s as part of research into selective growth-hormone secretagogue peptides, Ipamorelin became a useful tool compound for ghrelin receptor pharmacology research due to its receptor selectivity profile.
Ipamorelin Structure

Research Findings
Ipamorelin has been characterised in ghrelin receptor binding studies, growth-hormone-axis pharmacology, and structure-activity relationship work on selective GHS-R1a agonists. Its selectivity profile makes it a useful comparator for non-selective growth hormone secretagogues.
Key Areas of Research:
- •Ghrelin receptor: GHS-R1a binding and signalling
- •Selectivity: Non-stimulatory ACTH/cortisol profile in published assays
- •GH-axis: Pituitary somatotroph signalling research

Ipamorelin 10mg — research questions
Common questions for Australian researchers about Ipamorelin 10mg.
What is Ipamorelin?
Ipamorelin is a selective growth-hormone secretagogue pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH₂). It is supplied as an investigational research compound for in vitro laboratory research under the RUO framework.
What receptor does Ipamorelin target?
The ghrelin receptor, GHS-R1a, a class A G-protein coupled receptor. Ipamorelin is selective for GHS-R1a in published binding studies.
How does Ipamorelin compare to other GHRPs?
Published research describes Ipamorelin as having a non-stimulatory profile in ACTH and cortisol assays, in contrast to earlier-generation growth-hormone-releasing peptides. This distinguishes Ipamorelin in receptor selectivity research.
Is Ipamorelin legal in Australia?
Ipamorelin is classified as Schedule 4 (prescription-only) under the Australian Poisons Standard. It can be lawfully supplied for in vitro research purposes under the Research Use Only (RUO) framework. It is not listed on the Australian Register of Therapeutic Goods (ARTG) and is not a therapeutic good under the Therapeutic Goods Act 1989 (Cth).
How is Ipamorelin verified by Pillar Research?
Every batch is independently HPLC and mass spectrometry verified by a third-party Australian laboratory. The batch-specific Certificate of Analysis is downloadable from this page.
How should Ipamorelin be stored?
Store lyophilised vials at 2–8 °C, protected from light and moisture, in the original sealed vial. After reconstitution, store at 2–8 °C for short-term use or −20 °C for longer storage. Avoid repeated freeze–thaw cycles.
