Tirzepatide 99.9% Purity — Uther PeptideCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum, with the original poster claiming Janoshik tested Uther's Tirzepatide batch ZE301006. The reported purity was 99.868% and the quantity tested at 32.1mg against a 30mg label (7% deviation). 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.
