Research-Grade Compound

Ipamorelin is a synthetic pentapeptide and selective agonist at the growth hormone secretagogue receptor GHSR-1a, the receptor endogenous ghrelin acts on. Sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2, molecular formula C38H49N9O5, molecular weight 711.85 Da, CAS 170851-70-4. It belongs to the growth hormone releasing peptide (GHRP) class.

Purity standard: Ipamorelin is sourced to ≥99% by HPLC — sourcing spec. That is the specification every batch must meet, not a measurement of any one vial — the measured figure for a batch is on that batch's Certificate of Analysis.

Buying Ipamorelin — Frequently Asked Questions

What purity standard does Peptide.Express use for ipamorelin?

≥99% by reverse-phase HPLC with LC-MS/MS confirming the 711.85 Da molecular weight. Small peptides with non-natural residues carry a specific synthesis risk — incomplete D-amino acid incorporation produces diastereomers that share a mass with the target compound, so chromatographic resolution matters as much as the mass number on the CoA.

Where is the Certificate of Analysis for ipamorelin?

On this page and in the Peptide.Express lab results library. Each CoA is batch-specific and lists HPLC purity, LC-MS/MS mass confirmation, endotoxin result, testing laboratory and test date.

What testing does ipamorelin undergo before shipping?

Reverse-phase HPLC for purity, LC-MS/MS for molecular weight identity, LAL endotoxin testing, and visual QC. All performed by an independent third-party laboratory with a batch-specific Certificate of Analysis issued per lot.

How should ipamorelin be stored before and after reconstitution?

Lyophilized: -20°C, desiccated, protected from light, stable for 24 months. Reconstituted: 2–8°C, used within 14–28 days. Do not freeze the reconstituted solution and avoid repeated freeze-thaw cycles.

Is ipamorelin WADA prohibited?

Yes, at all times, in and out of competition. Growth hormone secretagogues acting at the ghrelin receptor fall under the World Anti-Doping Agency's growth hormone releasing factors category, and ipamorelin is named there.
