Merit Score
ModerateThe Merit Score is earned from zero through observable evidence only — independent COA volume, lab diversity, median measured purity, and evidence breadth. No vendor pays to influence it; affiliate relationships are disclosed separately and have zero input into the score.

Lab diversity reduces the risk of results being influenced by a commercial relationship with a single testing lab.
