Ipamorelin 5mg
Ipamorelin is a selective pentapeptide growth hormone secretagogue that acts through the ghrelin/GHS receptor (GHS-R1a). Developed by Novo Nordisk, it is considered one of the most selective GHRPs available, producing GH release without significant elevation of cortisol, prolactin, or ACTH levels.
This selectivity profile distinguishes Ipamorelin from earlier generation GHRPs such as GHRP-6 and Hexarelin, which tend to activate broader hormonal cascades. In preclinical studies, Ipamorelin has demonstrated dose-dependent GH release with a clean side-effect profile, making it a preferred research tool for studying isolated GH pathway effects.
Research applications of Ipamorelin span growth hormone physiology, bone density studies, body composition analysis, and metabolic regulation. It is frequently studied alongside CJC-1295 (no DAC) to investigate the synergistic amplification of GH release through dual GHRH/GHRP receptor activation. This combination has become a standard research protocol for studying the GH axis.

Where can a laboratory buy Ipamorelin in the EU?
Onyx Peptides supplies Ipamorelin for laboratory research across the European Union. We are operated by Vexio j. s. a. (IČO 54214530) in Slovakia and dispatch from within the EU, so there is no customs entry, no import duty and no border hold. Orders placed before 16:00 CET ship the same day, and shipping is free above €100.
How do I verify the batch of Ipamorelin I receive?
Each vial carries a batch number. Ask us for the Certificate of Analysis of the batch currently in stock — before you order, not after — and check that the batch number on the certificate matches the one printed on the vial. The analysis is performed by Janoshik Analytical, an independent laboratory in Prague, which will confirm a report it issued if you contact them with its identifier.
How is purity verified?
Every batch is independently tested by Janoshik Analytical using HPLC and Mass Spectrometry. A batch-specific Certificate of Analysis — also covering endotoxins and heavy metals — is available on request.
How fast is delivery?
We dispatch from within the EU, same day on orders placed before 16:00 CET. EU delivery typically takes 1–3 business days.
What payment methods do you accept?
We accept bank transfer (SEPA), including SEPA instant payments which usually arrive within seconds. Your order ships as soon as the transfer clears.
How should this be stored?
Store at 2–8 °C, protected from light. Once reconstituted, keep refrigerated and use within 30 days.
What is the intended use?
All products are supplied strictly for in-vitro laboratory and research use only. They are not for human consumption, veterinary, or clinical use.
