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.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

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.

Molecular weight: 711.86 g/mol

Storage and preparation

Keep unopened freeze-dried vials cold, sealed and out of the light; moisture is what degrades a lyophilized cake fastest. After reconstitution, refrigerate the solution and work within the stability window your protocol sets.

Buyer questions

Why does ipamorelin contain unusual amino acids?

Peptides built only from natural L-amino acids are broken down quickly by proteases. Incorporating aminoisobutyric acid, D-2-naphthylalanine and D-phenylalanine changes the backbone's shape and makes the molecule a poor enzyme substrate, while also tuning how it fits the ghrelin receptor. These residues are thought to contribute to its stability in experimental settings.

Is ipamorelin structurally related to ghrelin?

Not closely. Ghrelin is a longer, acylated hormone produced mainly in the stomach, while ipamorelin is a small synthetic pentapeptide that came out of medicinal chemistry. They share a receptor rather than a sequence, which is why ipamorelin is described as a ghrelin mimetic or receptor agonist instead of a ghrelin fragment or analogue.

When does Lilipeptide get paid?

Only after you confirm delivery. Until then the payment is held in escrow, and you can open a claim if anything is wrong with the order.
