How the Bureau picks
The pick is the vendor at the top of the Bureau's vendor list that stocks KPV. Scores come from the scorecard, which weighs lab documentation, consistency, shipping and price, and a vendor cannot buy a score. Before any order, match the lot number on the vial to a certificate from a named third-party lab. More in the vendor scorecard and the KPV guide.
