Tirzepatide 99.8% Purity — Wibson PeptideCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested Wibson Peptide's Tirzepatide, showing 99.756% purity via HPLC and a quantity of 17.07mg against a 15mg label (13.8% over). However, the lab's signature is not directly verifiable, and the test is stale (over 1 year old). This should be treated as community signal, not confirmation.
