Albert's Verdict

Ipamorelin is the cleanest GHS-R1a agonist in the catalog — highly selective for pituitary release with minimal cortisol or prolactin signal. That selectivity is exactly what you want when isolating ghrelin-receptor mechanisms.

Product Description

Ipamorelin is a synthetic pentapeptide that selectively binds the ghrelin / GHS-R1a receptor. Unlike non-selective GHS-R1a ligands, Ipamorelin shows minimal cross-activation of ACTH, cortisol, or prolactin pathways, making it a frequently chosen reference compound for receptor-selectivity research.

Research FAQ — Ipamorelin

Frequently asked questions about this compound for laboratory researchers.

What is Ipamorelin?+
Ipamorelin is a selective pentapeptide GHS-R (ghrelin-receptor) agonist. The 1998 publication describing its discovery characterized it as a selective growth hormone secretagogue in research models, with reduced reported effects on cortisol and prolaktin.
Cited: PMID 9849822
How is Ipamorelin different from GHRP-2 or GHRP-6 in research literature?+
Published comparative literature highlights Ipamorelin's selectivity for GHS-R and its reduced effect on other pituitary hormones relative to GHRP-2 and GHRP-6 in animal research models.
Cited: PMID 18430761
Is Ipamorelin commonly paired with CJC-1295 No DAC in research protocols?+
Yes — research literature describes combined administration as a way to investigate complementary GH-release pathways (GHRH-receptor + GHS-R). BioInfinity Lab offers a pre-blended CJC-1295 + Ipamorelin vial for research convenience.
How should Ipamorelin be stored?+
Lyophilized at −20 °C protected from light; reconstituted held at 2–8 °C and typically used within 30 days. Refer to the product COA.
