Tirzepatide 99.8% Purity — Vendor pending verificationCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested the product, reporting 99.85% purity via HPLC + MS and a quantity of 21.07mg (0.33% deviation from 21mg label). The test is recent (under 3 months). However, the lab's signature is not directly verifiable from this source, and the image has passed through at least one re-share, creating a chain-of-custody gap. This should be treated as community signal, not confirmation.
