COA standards

We publish vendor badge notes tied to evidence URLs. Independent COA badges expect third-party lab paperwork matching a batch tied to a live SKU, issued within twelve months.

• HPLC purity lines should identify method and reported purity.
• Endotoxin reporting varies by lab format. Capture what the vendor publishes verbatim.
• Older COAs remain visible on profiles even when the recency badge drops.
