Ipamorelin
$63.35
Ipamorelin is a selective, third-generation growth hormone secretagogue and ghrelin receptor agonist. It stimulates GH release with high selectivity and minimal effect on cortisol or prolactin, making it a preferred tool in GH axis research.

Product Information
Ipamorelin | Selective GH Secretagogue — Research Grade
Ipamorelin is a pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) and selective agonist of the ghrelin receptor (GHS-R1a). Its high selectivity profile distinguishes it from earlier-generation secretagogues such as GHRP-2 and GHRP-6.
Mechanism of Action
- GHS-R1a agonism — directly activates the growth hormone secretagogue receptor in the pituitary and hypothalamus
- Selective GH release — stimulates GH without significant elevation of ACTH, cortisol, or prolactin
- Synergy with GHRH — GH pulse amplitude increases markedly when co-administered with GHRH analogues in research models
Research Areas
Ipamorelin is studied in GH deficiency, cachexia, bone density, and metabolic research. Its selectivity and clean side-effect profile in preclinical models make it a reference compound in GH secretagogue research.
For Research Use Only. Rainbow Peptide supplies Ipamorelin exclusively for in vitro and laboratory research purposes. Not for human or veterinary use.
