This COA was extracted from a community forum attachment. The original poster claimed a lab tested alicepeptides@gmail.com's tirzepatide, reporting 99.537% purity via HPLC and a quantity of 61.40mg (2.33% over label). However, the lab's signature is not directly verifiable from this source, and the image has passed through at least one re-share, creating a chain-of-custody gap. This test is also stale (over 1 year old).

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