QHP. Nexaph: 3 independent Janoshik assays, across 3 substances, median measured purity 99.7%, most recent 2026-01-27. QHP: 4 independent Janoshik assays, across 4 substances, most recent 2025-08-28. These are third-party Janoshik assays published against the vendor, not the vendor's own certificates.
We found no certificates of analysis anywhere on Nexaph's site, and we have not read QHP's site. A published COA is the vendor's own document; the assay figures elsewhere on this page are independent of it.
Nexaph states it ships to United States, United Kingdom, Worldwide, and QHP does not state one. Both are read from the vendors' own sites.
