Pentapeptide growth hormone secretagogue studied in vitro for selective GHS-R1a binding. ≥99% HPLC. Research use only. This guide covers identity, published research context, procurement checks, and storage — RUO only, no clinical claims.
What Ipamorelin is in published research
Ipamorelin is a synthetic pentapeptide growth hormone secretagogue with reported selectivity for the GHS-R1a (ghrelin) receptor over melanocortin and other off-target receptors in published in vitro work. Labs use the peptide as a selectivity reference standard in receptor-binding and cAMP signaling assays alongside other secretagogues such as GHRP-2 and hexarelin.
Each lot ships with ≥99% HPLC purity and MS identity verification of the unnatural residues (Aib, D-2-Nal, D-Phe). Net peptide content is reported on the CoA. Comparative selectivity work commonly pairs ipamorelin with GHRP-2 on the same plate; that batch documentation can be filed by SKU.
Hold lyophilized vials at -20 °C sealed and protected from light. Reconstitute with bacteriostatic water; aliquot reconstituted stock into single-use volumes before freezing to limit freeze/thaw.
CoA covers identity (MS), purity (HPLC), and net peptide content. Batch records by lot are available for compliance review.
The material class "Growth hormone secretagogue (research)" helps procurement teams group Ipamorelin with related reference peptides during comparative studies.
Sequence and identity
Ipamorelin identity on the catalog: Common name: Ipamorelin; Sequence: Aib-His-D-2-Nal-D-Phe-Lys-NH2; Length: 5 residues; Molecular formula: C38H49N9O5; Molecular weight: 711.86 g/mol; Appearance: White lyophilized powder; Purity (HPLC): ≥ 99%; Net peptide: Listed on CoA; Solubility: Soluble in bacteriostatic water. Copy these into receiving and LIMS before reconstitution.
Mechanisms studied in published research
Mechanism-focused research on Ipamorelin is typically conducted in cell lines or biochemical preparations that express the relevant receptor or binding protein for its class.
Design controls that include scrambled-sequence or orthogonal-receptor negative controls when your protocol evaluates Ipamorelin pharmacology in vitro.
Report effect sizes with lot number and CoA reference so results can be reproduced if the same Ipamorelin SKU is reordered later.
Avoid extrapolating in vitro binding or signaling readouts to whole-organism outcomes; RUO materials are not qualified for clinical investigation.
Procurement and identity verification
Request the lot-specific CoA for Ipamorelin at receipt. Verify SKU, variant size if applicable, and identity mass before the lot enters general storage.
Compare HPLC purity to your internal minimum for the peptide family. File chromatogram excerpts when your QMS requires raw data.
Enter net peptide content from the CoA into inventory before calculating molarity for Ipamorelin working stocks.
Attach purchase order, packing list, and CoA in one audit folder per lot.
Storage and reconstitution
Store lyophilized Ipamorelin sealed at -20 °C protected from light unless the CoA states otherwise.
Reconstitute with bacteriostatic water or a buffer validated for your assay pH. Aliquot to limit freeze-thaw.
For oxidation-sensitive sequences in Ipamorelin, minimize open-vial time at room temperature during weighing.
See our lyophilized storage guide for institution-scale SOP examples and aliquot labeling conventions.
Comparative reference points
Researchers comparing Ipamorelin with adjacent catalog references often evaluate the following SKUs in parallel plates:
Hexarelin (hexarelin) — compare identity table and CoA fields side by side.
Use matched reconstitution buffers and stock concentrations when running comparative binding or signaling assays.
Document reviewers should cross-link this guide with the product certificate of analysis and internal receiving SOP.
When publishing methods, cite lot number, SKU, reconstitution buffer, and stock concentration so external labs can interpret your figures.
Institutional procurement may require RUO acknowledgment at checkout; store that acknowledgment beside batch records for audits.
If assay results drift across quarters, compare storage logs and CoA revision before questioning sequence integrity.
Third-party summaries, when available, should be filed as supplements—not replacements—for CoA identity data.

Frequently asked questions
Is Ipamorelin for clinical programs?
No. It is sold for research use only (RUO) to qualified buyers.
What purity should we expect for Ipamorelin?
Listings target ≥99% HPLC with MS identity on the lot CoA. Verify on receipt, not from marketing copy alone.
How do we calculate molarity for Ipamorelin?
Use net peptide content from the CoA divided by molecular weight, then divide by reconstitution volume.
Can we mix lots of Ipamorelin in one stock?
Avoid mixing lots unless your protocol explicitly requires it. Mixed lots break traceability.
Where is the Ipamorelin product listing?
View the catalog PDP for Ipamorelin for variant SKUs and quote or purchase options.
