Tirzepatide 99.7% Purity — Tianjin Finder Chemical TfcCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested Alice Peptides' tirzepatide, reporting 99.737% purity. However, the quantity tested was significantly under-dosed at 33.29mg against a 60mg label. The lab's signature is not directly verifiable, and the image has passed through at least one re-share, indicating a chain-of-custody gap. This should be treated as community signal, not confirmation.
