Tirzepatide 99.7% Purity — Top PeptideCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested TOP's tirzepatide, showing 99.681% purity via HPLC and a quantity deviation of +10.03% (66.02mg tested vs 60mg labeled). The test is recent (under 3 months). 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.
