This COA was extracted from a community forum / Discord channel. The original poster claimed a lab tested QSC's Tirzepatide (batch TZ 30mg 1 vial) at 99.768% purity, with a tested quantity of 32.87mg against a 30mg label. However, the lab's signature is NOT directly verifiable from this source, and the image has passed through at least one re-share. This should be treated as community signal, not confirmation.
Watch out for
- stale (1+ years old)
- no endotoxin test
- chain-of-custody gap
