About this compound
Ipamorelin
Ghrelin-analogue pentapeptide
First disclosed
1998
Ipamorelin is a pentapeptide growth-hormone secretagogue known for how cleanly it selects the ghrelin receptor (GHS-R1a) over related targets. That selectivity is exactly why it shows up so often as a reference ligand in secretagogue research.
Selective GHS-R1a agonism is studied in vitro for ghrelin-receptor signalling with minimal cross-activity.

Ipamorelin is a pentapeptide growth hormone-releasing peptide (GHRP), supplied by MyPeptides for laboratory research use only.
Ipamorelin is a pentapeptide growth-hormone secretagogue (Aib-His-D-2Nal-D-Phe-Lys-NH₂, CAS 170851-70-4) known for how cleanly it selects the ghrelin receptor GHS-R1a over related targets — which is why it is widely used as a selective reference ligand.
It is supplied as a 5 mg lyophilised vial. For additive-signalling models, the CJC-1295 + Ipamorelin blend pairs it with a GHRH-receptor agonist at a fixed 5 mg + 5 mg ratio.
Store at −20 °C, protected from light. See the growth-hormone axis range for GHRP-2, GHRP-6, hexarelin and the GHRH analogues. For in-vitro research use only.

Professional service end to end
Shipping to mainland EU took 3 working days, tracked the whole way. Vials arrived intact, labels crisp, seals unbroken. Reordering next month.

Great documentation
The little details matter - proper cold-chain, tamper-evident seals, and a CoA that actually reads like a lab report and not a marketing sheet.
Marcus T.Berlin, DE · 15 May 2026
Quality packaging, quick dispatch
Clean product, no discoloration, correct fill. Certificate of analysis was in the box AND emailed. Very straightforward experience.

Vials in perfect condition
Ordered a bundle to save on shipping - all vials arrived in one insulated pack, labels identical batch, CoA covers the lot. Great value.
