Third-Party Independent Testing
Every batch
on the record.
Verify yours.
Every compound is sent to an independent, third-party laboratory — Janoshik — before it ships. Each COA includes HPLC-MS chromatogram data, mass identification, and average peptide purity for that batch.
Testing Methodology
Independent testing,
every batch.
Every batch is sent to Janoshik, an independent analytical laboratory specialising in peptide chemistry. No batch ships without a signed Certificate of Analysis. Results are verified via the Janoshik public verification portal.
Verify a result at Janoshik →Identity
Mass spectrometry (MS) confirms molecular identity matches the theoretical value for the compound.
Purity
Reverse-phase HPLC with UV detection quantifies peptide content and separates impurities.
Peptide Content
Actual peptide mass per vial (mg) is measured and reported — not just stated on the label.
Appearance
Visual inspection of lyophilized product confirms correct physical presentation and colour.
