Independent Analytical Testing

The certificates listed below document analytical testing performed on specific submitted samples and batches. We use PeptideVerify for independent third-party analytical testing, providing additional verification of product identity, purity and batch-specific results. Each certificate provides the relevant analytical results, batch information and independent verification details.

🔎 Certificate Verification

To independently verify a certificate, simply copy the Certificate ID shown on the relevant certificate, visit PeptideVerify, and enter the Certificate ID into their verification system.

This allows you to check the corresponding test record and verify the analytical results associated with that certificate.
