Finnrick Analytics A (GREAT) rating for Retatrutide and BPC-157. 99%+ purity verified. 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.
Peptides listed 7
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.
