Important Notice
This product is intended for laboratory and research use only. Not for human or veterinary use. By purchasing, you confirm this product will be used exclusively for in-vitro research purposes.
Reconstitution Required
This peptide ships lyophilized (dry powder) and requires bacteriostatic water to reconstitute before use. BAC water is sold separately.
Recommended: BAC water · stable for 28 days at 2-8°C once mixed.
When This Product May Not Suit Your Research
- ⚠If your research requires sustained GH elevation — Ipamorelin produces pulsatile, not continuous, GH release.
- ⚠If your model needs oral bioavailability — Ipamorelin must be administered parenterally.
- ⚠If your study protocol prohibits GHRP-class compounds — Ipamorelin is a growth hormone secretagogue.

About Ipamorelin
About Ipamorelin
Ipamorelin (CAS: 170851-70-4) is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) belonging to the growth hormone secretagogue (GHS) class. It was developed as a highly selective agonist of the growth hormone secretagogue receptor (GHS-R1a, also known as the ghrelin receptor). Among the GHS peptide family, Ipamorelin is notable for its selectivity in stimulating GH release with minimal effects on adrenocorticotropic hormone (ACTH), cortisol, or prolactin secretion.
Mechanism of Action
Ipamorelin binds to the GHS-R1a receptor on pituitary somatotrophs, triggering growth hormone release through phospholipase C activation and intracellular calcium mobilization. Unlike other growth hormone secretagogues such as GHRP-6 or hexarelin, ipamorelin demonstrates a narrow selectivity profile, stimulating GH release in a dose-dependent manner without appreciably altering cortisol, ACTH, or prolactin levels. Additional research has explored its prokinetic effects on gastrointestinal motility through vagal cholinergic pathways.
