How the score is built

Third-party test reports: are they recent, lot-linked, and do they use methods that can actually prove identity and amount?

  • Published test reportsClear

    2 of 2 document links we tried opened publicly.

  • Reports tied to a lotFlagged

    The reports we saw are not tied to a lot or batch, so they cannot tell you about the specific vial you would receive.

  • Analytical methodClear

  • Named third-party labClear

Inside the reputation pillar (12% of the model)
