Our Verification Process
Four rigorous pillars ensure only trustworthy vendors earn the PeptiNox verification badge.
COA Verification
We independently verify Certificates of Analysis, checking HPLC chromatograms, mass spectrometry data, and batch-specific documentation for authenticity and accuracy.
Third-Party Testing
Products are purchased anonymously and submitted to independent laboratories for blind purity and identity testing. No vendor-supplied samples accepted.
Business Verification
We verify business registration, physical address, domain history, and operational consistency. Legitimate businesses stand behind their products.
Feedback Analysis
Aggregated community feedback from researchers, forums, and direct reports. We analyze patterns over time, not individual reviews.
