This COA was extracted from a community forum, with the original poster claiming Janoshik tested PGB's Retatrutide batch PGB-R24-1. The reported purity was 99.702%, and the tested quantity was 28.09mg against a 24mg label, a 17.04% deviation. The lab's signature is not directly verifiable from this source, as the image has passed through at least one re-share, creating a chain-of-custody gap.

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