What is Ipamorelin?

Ipamorelin is a synthetic pentapeptide and selective growth hormone secretagogue. With the molecular formula C₃₈H₄₉N₉O₅ and a molecular weight of 711.9 g/mol (CAS: 170851-70-4), Ipamorelin is derived from the growth hormone-releasing peptide (GHRP) family and exhibits unique selectivity for growth hormone release.

Published Research

Raun et al. (1998) characterized Ipamorelin's selective binding to GHS-R1a receptors and its effects on growth hormone release in pituitary cell cultures (PMID: 10698741).

PMID: 10698741VERIFY PMID

Johansen et al. (2002) investigated Ipamorelin's receptor binding kinetics and signaling pathways in CHO cells expressing GHS-R1a (PMID: 11916262).

Mechanism of Action

GHS-R1a Receptor

Ghrelin receptor agonism

Ipamorelin selectively activates the ghrelin receptor (GHS-R1a) on somatotrophs, stimulating growth hormone release without significantly affecting other pituitary hormones (PMID: 10698741).

Intracellular Signaling

IP3/DAG/Ca2+ cascade

Receptor activation triggers phospholipase C-mediated signaling, increasing intracellular calcium and activating protein kinase C (PMID: 11916262).

Storage & Handling

Temperature:-20°C for long-term storage

Light Sensitivity:Protect from direct light

Stability Duration:Stable for 24 months when stored properly

Selective mechanism distinguishes Ipamorelin from non-selective GHRP compounds.
