Third-party lab
This COA was tested by an independent third-party lab, Peptide Test. It reports 99.819% purity for YC's Tirzepatide (batch Yiwu Changtu orange cap). However, the quantity tested was 14.03% over the labeled 60mg, and there is no information on endotoxin levels or the test method used for purity. The test is stale, being over a year old. Customers can cross-check on the lab's public verification URL.
Watch out for
