Retatrutide 99.3% Purity — Zlz PeptideCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum, with the original poster claiming Vanguard Laboratory tested ZLZ's Retatrutide batch ZLZ R-003. The reported purity was 99.26%, and the tested quantity was 15.93mg against a 15mg label. However, the lab's signature is not directly verifiable, and the test is stale (over a year old).
