Janoshik tested this tirzepatide batch (blue cap 308020-2/17/25) at 99.71% purity. Quantity matched the label within 1% (30.17mg tested vs 30mg label). However, the test is stale (over 1 year old), the test method and endotoxin status are unknown, and the COA was submitted by a community member rather than directly from the lab. Customers can cross-check on the lab's public verification URL.
