Independent testing
Every Batch Ships With Its Certificate of Analysis
Purity is not something we ask you to take on trust. Each batch is analysed by Bioviridian, an independent laboratory, and the certificate is tied to the lot you receive — not to the product line.
- Identity Confirmed by mass spectrometry against the reference sequence.
- Purity Measured by RP-HPLC at 214 nm, with the chromatogram published on the certificate.
- Content Quantified by HPLC so the stated milligram figure is verified, not assumed.
- Verifiable Every certificate carries a web verification code and QR, checkable directly with the lab.
Peptide blends
Multi-Compound Blends, Compounded and Tested Together
Twenty-one pre-combined formulations supplied in a single vial. The components are compounded and tested as one product, which removes the step of combining them at the bench and keeps the documentation to a single certificate.
