Tirzepatide 99.9% PurityCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum / Discord channel. The original poster claimed Peptide Test lab tested Bio's Tirzepatide (batch Biostratigx TZ 20mg 1 vial) at 99.934% purity, but the lab's signature is NOT directly verifiable from this source. The reported quantity showed a significant +25% deviation from the label (20mg vs 25mg tested). This test is stale (over 1 year old) and lacks endotoxin information. The image has passed through at least one re-share, creating a chain-of-custody gap.
