Tirzepatide 99.8% 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 the vendor's product, reporting 99.76% purity and a quantity of 10.15mg for a 10mg label, but the lab's signature is NOT directly verifiable from this source. This test is stale (over 2 years old) and lacks endotoxin information. This should be treated as community signal, not confirmation, due to the chain-of-custody gap.
