Notes
- Over 30 batch-numbered certificate PDFs are downloadable without a login.
- States a minimum purity specification of 98%, which is lower than most stated figures on this list, alongside a claim that most compounds test above 99%.
- The site serves the same page for unrecognised URLs, so a certificate page can appear to exist at addresses where it does not.
