Independent Certificates of Analysis

Every Six4Labs batch is verified by an independent ISO 17025-accredited lab using HPLC and Mass Spectrometry. Each vial in your hand is tied to a specific batch number and certificate — not a generic sample card.

Methods

HPLC purity, mass spec identity, KF water, LAL endotoxin.

Every release batch is tested against the same panel — no exceptions. If a batch fails any spec line item, it is not packaged for sale.
