Certificate of Analysis

Accredited, independent lab

Reports come from a third-party ISO-accredited laboratory, never our own bench.

Lot matches your vial

The lot number on the report should match the one printed on your label.

HPLC purity

The headline figure for that specific batch. Every report prints the result next to the acceptance threshold it was judged against.

Identity confirmed

LC-MS confirms the molecular weight matches the target peptide.

The full seven-part panel

Purity, net peptide content, identity, fentanyl, heavy metals, sterility and endotoxin. Sterility and endotoxin should both read PASS.
