Ipamorelin 2mg

Ipamorelin at a glance

Ipamorelin belongs to the growth-hormone secretagogue family and was developed as a smaller, more selective successor to the early GHRP hexapeptides. Its five residues, Aib-His-D-2-Nal-D-Phe-Lys-NH2, include the unnatural amino acid aminoisobutyric acid and two D-configured residues that help it resist proteolysis. The formula is C38H49N9O5, giving a molecular weight of 711.86 g/mol. It is not derived from ghrelin itself; it mimics ghrelin's action at the receptor while sharing none of its sequence.

Price and availability

A single 2mg vial from EuropePeptide, shipped from the Netherlands. At $23.99 for the kit, that works out to $11.99 per mg. Across 19 brands listing Ipamorelin here, the middle half of prices falls between $0.689 and $4.80 per mg; this kit is above the typical range. As with every order here, the brand is paid only after you confirm delivery.

What it is studied for

Ipamorelin is an agonist of GHS-R1a, the receptor through which the stomach hormone ghrelin acts. On pituitary somatotrophs, receptor activation couples to phospholipase C and a rise in intracellular calcium, releasing stored growth hormone; hypothalamic receptors are thought to amplify this by modulating GHRH and somatostatin input. In early animal pharmacology, its release profile was reported to be more selective than that of GHRP-6 or GHRP-2, with little change in ACTH or cortisol even at higher exposures. Effects on appetite appear weaker than those of GHRP-6 in published models, although direct comparisons are limited.

Research and regulatory status

Most ipamorelin data come from rodent and other animal models looking at GH pulsatility, bone mineral content, and gut motility after surgery. A pharmaceutical developer took the compound into mid-stage human trials for postoperative ileus, but that program did not lead to an approved product, so ipamorelin remains a research tool. On GLP1 Forum Escrow it is listed by multiple brands, which makes comparing price per mg alongside each batch's lab report the practical way to judge listings.

Checking the lab data

Identity checks should show a mass spectrum consistent with 711.86 g/mol, with the protonated ion appearing near 712. Because the sequence contains D-residues and Aib, a careful lab may also comment on diastereomeric impurities that a standard HPLC run can miss. The report should give HPLC purity with a chromatogram, net content measured against the stated fill, a white lyophilized cake, and a batch code that matches the vial.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Concentration arithmetic: one 2 mg vial dissolved in 2 mL gives 1 mg/mL, or 2 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.
