Tirzepatide 99.7% 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 99.71% purity via HPLC + MS, with a tested quantity of 43.87 mg. However, the lab's signature is not directly verifiable from this source, and the image has passed through at least one re-share. This should be treated as community signal, not confirmation.
