THCA proof kit

The shortest version of how to verify a THCA product yourself: read the batch certificate of analysis, check who tested it, and run the total-THC math. Information only — The Leaf Concierge sells nothing.

What makes a product verifiable

  • A batch COA from a named, accredited third-party lab.
  • A batch ID on the COA that matches the one on the package.
  • A recent test date and a pass on every safety panel.
  • Total THC calculated with the decarboxylation formula, not the delta-9 line alone.
