Description

Ipamorelin is a 5-amino-acid pentapeptide studied as a selective growth-hormone secretagogue in preclinical research. It is characterised as a GHRP (growth hormone-releasing peptide) that activates the ghrelin/GHS-R1a receptor, and is examined for GH-selective release with minimal cortisol/prolactin co-activation in research models. LiveWell supplies it as a lyophilized vial strictly for in-vitro laboratory research.

Chemical information

Name: Ipamorelin
CAS Number: 170851-70-4
Sequence: Aib-His-D-2-Nal-D-Phe-Lys-NH2
Type: Synthetic pentapeptide (GHRP class)
Molecular formula: C38H49N9O5
Molecular weight: approximately 711.85 g/mol
Available sizes: 5mg, 10mg

Mechanism studied

Ipamorelin is examined in the literature as a selective ghrelin-receptor (GHS-R1a) agonist. Unlike earlier-generation GHRPs (GHRP-6, Hexarelin), Ipamorelin’s receptor selectivity is the property most often studied for producing GH release with minimal co-activation of cortisol and prolactin pathways in research models.

Studied in

Selective GH-release and ghrelin-receptor signalling research
Comparative GHRP research (vs GHRP-2, GHRP-6, Hexarelin)
Combined GHRH + GHRP synergy research (with Sermorelin, CJC-1295, Tesamorelin)
Receptor-selectivity and structure-activity analysis

Storage & handling

Store the lyophilized vial refrigerated at 2–8°C, protected from light and heat
Reconstitute with bacteriostatic water; reconstituted material has a shorter storage window
Follow your laboratory’s standard peptide handling protocol

Frequently Asked Questions

What is Ipamorelin?

Ipamorelin is a synthetic pentapeptide (CAS 170851-70-4) studied as a selective ghrelin-receptor (GHS-R1a) agonist. Supplied as a lyophilized vial strictly for in-vitro laboratory research.

What is the chemical structure of Ipamorelin?

Ipamorelin has the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2, molecular formula C38H49N9O5, and a molecular weight of approximately 711.85 g/mol. Full documentation is included with each Certificate of Analysis.

How does Ipamorelin differ from other GHRPs like GHRP-6 or Hexarelin?

Ipamorelin is studied for its receptor selectivity — activating GHS-R1a with minimal co-activation of cortisol and prolactin pathways, a distinguishing feature from earlier-generation GHRPs such as GHRP-6 and Hexarelin in comparative research.

What is the difference between Ipamorelin alone and the CJC-1295 + Ipamorelin blend?

This vial contains Ipamorelin only. The CJC-1295 + Ipamorelin blend pairs it with a GHRH analog in a single vial for GHRH/GHRP synergy research. Which format suits a study depends on the research design.

What purity is LiveWell Ipamorelin, and is a COA included?

Every batch is third-party tested at ≥99% purity by HPLC, with mass spectrometry identity confirmation and LAL endotoxin testing. A batch-specific Certificate of Analysis is published on our COA page.

What sizes are available?

Ipamorelin is supplied in 5mg and 10mg lyophilized vials.

How should Ipamorelin be stored and reconstituted?

Store refrigerated at 2–8°C, protected from light and heat. Reconstitute with bacteriostatic water; reconstituted material has a considerably shorter storage window.

Is Ipamorelin a drug or supplement?

No. Ipamorelin is a research compound sold strictly for laboratory use only. It is not a drug, dietary supplement, food or cosmetic, and it is not intended for human or animal consumption.
