What this page can say
The names below are facts about certificates we opened. They are not a ranking of laboratories against one another, and they carry no HPLC purity score. Seller certificate tier is still the ranking on every price page.
The purity and dose gate is written and off. We do not invent pass or fail from missing certificates of analysis.
Deferred: HPLC scores, a lab quality letter, and turning the purity gate on. Those need quality data we are entitled to use. They are not shipped.
