This COA was tested by Janoshik, an independent third-party lab. The report indicates 99.718% purity for SRY's Tirzepatide (batch Feb Yellow Cap). However, the tested quantity was significantly lower than labeled (20.74mg vs 40mg, a -48.15% deviation), and there is no information on the test method, test type, or endotoxin status. The test is stale, over a year old. Customers can cross-check on the lab's public verification URL.
