This COA was extracted from a community forum / Discord channel. The original poster claimed Numega Labs tested QSC's tirzepatide (batch 'brown caps'), but the lab's signature is NOT directly verifiable from this source — the image has passed through at least one re-share. The test date is stale (over 1 year old), and purity, quantity, and endotoxin results are all unknown. This should be treated as community signal, not confirmation.

Watch out for
  • chain-of-custody gap
  • stale (1+ years old)
  • no purity data
