Buying Ipamorelin — Frequently Asked Questions

What purity standard does Peptide.Express use for ipamorelin?

Sourced to a ≥99% HPLC specification. Where a certificate reports a mass, compare it with 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. Sourced against a ≥99% HPLC purity specification. Third-party Certificates of Analysis are published where on file.

What testing does ipamorelin undergo before shipping?

Where a certificate is on file, it shows the assays that laboratory reported. Those can include reverse-phase HPLC, LC-MS/MS, an endotoxin result, and visual QC. A missing line is not a pass and is not proof the assay never ran.

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.
