Finnrick Analytics A rating. Third-party testing includes HPLC-MS, USP endotoxin, and USP sterility testing. observed

A COA describes one batch's purity. It is a document about a vial, not evidence about an effect, and it never grades a claim on this site — the grading rubric names what qualifies.

Linked names have a record here; the others we hold nothing on yet. A vendor listing a compound says nothing about the evidence for it.
