third-party

Red Leaf publishes purity reports on individual product pages (e.g., Retatrutide 30mg listed at 99.79% purity) and states they use "internal and independent third-party laboratories" for validation. The third-party lab name is not consistently disclosed for every product, and the report mix between internal and external should be verified by buyers. 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 8

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.
