Tirzepatide 99.8% Purity — Hong Kong Lejian BiotechnologyCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested Lejian Biotech's Tirzepatide, reporting 99.759% purity and 11.58 mg tested quantity. However, the lab's signature is not directly verifiable, 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.
