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.
