This COA was extracted from a community forum attachment. The original poster claimed a lab tested the vendor's product, reporting 99.562% purity via HPLC for Retatrutide. The tested quantity of 18.39mg significantly exceeded the 15mg label, a 22.6% deviation. However, the lab's signature is not directly verifiable from this source, and the image has passed through at least one re-share, indicating a chain-of-custody gap. This should be treated as community signal, not confirmation.

Watch out for
  • chain-of-custody gap
  • unknown lab
  • no endotoxin test
