Buyer guide · for buyers who want to verify everything
The Verify-Everything Kit
The right amount of trust in this market is almost none, verified upward. This lane is for readers who want to run the audit themselves: match batch numbers, look up lab accreditation in the accreditor’s public directory, recompute total THC from the raw lines, and check test dates. Twenty minutes of literacy, applied to every vendor forever.
What matters most here
- The 10-point COA checklist — the printable routine behind our reviews
- Accreditation lookups: A2LA and ANAB directories take two minutes and settle the lab question
- The math: THCA × 0.877 + Δ9, run against the advertised number every single time
Honest note · Do not accept a QR code that resolves to a vendor-hosted PDF as verification — the chain you want ends at the laboratory, and a report the vendor controls is a screenshot, not evidence.
