What Is Ipamorelin?

Ipamorelin was first described in the late 1990s as a growth hormone secretagogue, a compound that binds the ghrelin/growth hormone secretagogue receptor (GHS-R1a) on pituitary cells. Only five amino acids long, it is one of the smaller peptides in this class.

What makes it a useful laboratory reference is selectivity. In animal-model studies, ipamorelin stimulated growth hormone release with little effect on cortisol or prolactin, which is not true of every secretagogue. That narrow profile is why researchers choose it when they want to isolate GH-release signalling from other pituitary responses.

Nation Peptides supplies ipamorelin strictly as a research material for in vitro and laboratory use, and makes no medical or therapeutic claims about it.

Ipamorelin in Secretagogue Research Panels

Growth hormone research rarely relies on one mechanism. Ipamorelin works through the ghrelin receptor, while a growth hormone-releasing hormone (GHRH) analog acts on a different receptor. Many panels place the two side by side.

  • Class: Ipamorelin 10mg: Ghrelin receptor agonist (GHS-R1a). Tesamorelin 10mg: GHRH analog (GHRH receptor).
  • Structure: Ipamorelin 10mg: Pentapeptide, 5 amino acids. Tesamorelin 10mg: 44 amino acids with a trans-3-hexenoyl group.
  • CAS number: Ipamorelin 10mg: 170851-70-4. Tesamorelin 10mg: 218949-48-5.
  • Price: Ipamorelin 10mg: $49.99. Tesamorelin 10mg: $69.99.

Researchers comparing tesamorelin and ipamorelin can buy Tesamorelin from the same catalogue, with a batch certificate for each lot.

Batch VNA7TB Certificate

The certificate for the lot now shipping reports 99.9% purity by HPLC, tested May 11, 2026 by Freedom Diagnostics. Identity, purity, sterility, and endotoxin results are all listed as passed. Each order is matched to a verified batch before packing. You can confirm the lot with the batch lookup or the QR code on the vial.

Building the Rest of the Order

Ipamorelin ships as a lyophilized powder, so a diluent is part of most orders. Many labs add a 10ml vial of bacteriostatic water for peptides at checkout. Other compounds that labs often order in the same shipment include the MOTS-C for sale listing, a mitochondrial-derived peptide, and the option to buy BPC 157 for tissue-repair models.

Ipamorelin FAQ

What is ipamorelin?
Ipamorelin is a synthetic pentapeptide that binds the ghrelin receptor (GHS-R1a). Laboratories use it as a reference growth hormone secretagogue. Nation Peptides supplies it for research use only.
Where can I buy Ipamorelin 10mg with a COA?
You can buy Ipamorelin 10mg on this page. The certificate for the lot shipping now is shown: batch VNA7TB, 99.9% by HPLC, tested May 11, 2026. Each order is matched to a verified batch and COA before packing.
How much does ipamorelin 10mg cost?
A single 10mg vial is $49.99. The 5-pack saves 8% per vial, about $45.99 each, and the 10-pack saves 15% per vial, about $42.49 each.
What are the CAS number and molecular weight of ipamorelin?
The CAS number is 170851-70-4. The molecular formula is C38H49N9O5 and the molecular weight is 711.85 g/mol.
What is the difference between ipamorelin and tesamorelin?
Ipamorelin is a five-amino-acid ghrelin receptor agonist. Tesamorelin is a 44-amino-acid analog of growth hormone-releasing hormone. They act on different receptors, so researchers often compare them side by side.
How is lyophilized ipamorelin stored?
Keep the lyophilized vial frozen and away from light. After reconstitution, refrigerate it and check the COA for stability notes.
Is ipamorelin for human use?
No. It is supplied for in vitro and laboratory research by qualified researchers aged 21 or older, and is not intended for human or animal consumption.
