Batch documentation

A COA trail you can actually open.

Research purchasing should feel auditable. We surface lot-level certificates where they matter — next to the compound, before the cart.

Certificate

Lot-linked COAs

  • Every released batch

    COA context is tied to the lot — not a generic quality claim pasted onto every SKU.

  • Horizon-tested records

    Third-party analytical testing sits behind available certificates so buyers can verify identity and purity.

  • Visible before checkout

    Browse published documentation on the transparency page, then confirm lot details on the product record.
