About Ipamorelin
Ipamorelin is a synthetic pentapeptide studied as a growth hormone secretagogue (GHS) — a class of research compounds investigated for their interaction with the ghrelin receptor, also known as the growth hormone secretagogue receptor (GHS-R1a). Binding at this receptor is of interest to researchers studying the signalling pathways involved in growth hormone release.
Ipamorelin is frequently referenced in the literature as acting more selectively at the ghrelin receptor than some earlier-generation secretagogues, with comparatively limited activity at receptors linked to cortisol, prolactin and acetylcholine release. This selectivity profile is part of why it is commonly used as a reference compound in growth hormone secretagogue research.
As supplied, Ipamorelin is a lyophilised (freeze-dried) powder, a standard presentation for peptide stability during storage and transport. For related compounds and background on peptide classifications, see our peptide Compound Library.
