Tirzepatide 99.6% Purity — HomopeptideCertificate 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 99.637% purity via HPLC + MS and a quantity of 31.75mg for a 30mg label. 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.
