What supports confidence

  • Batch-specific COAs are publicly offered.
  • Vendor states each product batch is independently tested for identity and purity.
  • Published purity-guarantee policy creates an accountability mechanism.

What limits confidence

  • Some testing claims originate from the vendor and require continuing outside verification.
  • Public operating history is shorter than ideal for a maximum track-record score.
