Tirzepatide 99.9% Purity — Allen Biotechnology Co AbcCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested the vendor's product, reporting 99.931% purity for Tirzepatide. However, the lab's signature is not directly verifiable, and the image has passed through at least one re-share. The tested quantity showed an 18.64% deviation from the 50mg label, and endotoxin status is unknown. This should be treated as community signal, not confirmation.
