Why Research Laboratories Select Ipamorelin
Ipamorelin is among the most studied selective growth hormone secretagogue receptor agonists in current endocrine and pituitary research. Its high selectivity for GHS-R1a in experimental models — without significant activity on other pituitary hormone pathways — makes it a valuable reference compound for laboratories investigating GH secretagogue signaling, receptor pharmacology, and comparative GHRP studies.
- Synthetic pentapeptide — 5 amino acid sequence with non-proteinogenic residues for receptor selectivity
- Selective GHS-R1a agonist — studied for minimal cross-reactivity with other pituitary hormone systems in research models
- Activates Gq/PLC-dependent calcium signaling pathways in experimental systems
- Referenced in peer-reviewed literature including Journal of Endocrinology and Growth Hormone & IGF Research
- Lyophilized format ensures stability and reproducibility across experimental runs
- Batch and lot identifiers on all labeling for full laboratory documentation compliance
Research Background
Ipamorelin was first described in scientific literature by Raun et al. in 1998 in the European Journal of Endocrinology. Preclinical studies in rodent and swine models have examined its selective GHS-R1a binding properties and downstream growth hormone release patterns. Johansen et al. (1999) examined its effects on longitudinal bone growth in rodent models, published in Growth Hormone & IGF Research.

Frequently Asked Questions
What is Ipamorelin?
Ipamorelin (NNC 26-0161) is a synthetic pentapeptide and selective agonist of the ghrelin/growth hormone secretagogue receptor (GHS-R1a). It is supplied strictly for scientific, analytical, and in-vitro laboratory research use only.
How does Ipamorelin differ from other GHRPs like GHRP-2 and GHRP-6?
In experimental models, Ipamorelin demonstrates high selectivity for GHS-R1a without significant activity on other pituitary hormone pathways, distinguishing it from GHRP-2 and GHRP-6 which show broader hormonal activity profiles in research settings.
