Quality Assurance Protocol
Independent HPLC & Mass Spectrometry Reports
At PEPTIDESSHOP, purity is verified independently for every synthesized lot. Below you can search any batch lot number to inspect third-party Certificates of Analysis (CoA).
Lookup Certificate of Analysis (CoA)
Enter the lot number printed on your vial's label (e.g. NX-2026-BPC998):
Reverse-Phase HPLC
Confirms chemical purity levels exceed 99.0% with sharp single-peak retention times.
Tandem Mass Spectrometry (MS)
Confirms exact molecular weight and amino acid sequence fidelity against reference standard.
Endotoxin & Sterility Assay
LAL testing confirms zero bacterial endotoxins (<0.05 EU/mg) for research integrity.
