Retatrutide 99.7% Purity — STG Group TestersCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested STG Group Testers' retatrutide, reporting 99.67% purity via HPLC and a tested quantity of 31.41 mg. However, the lab's signature is not directly verifiable, and the image has passed through at least one re-share, creating a chain-of-custody gap. This should be treated as community signal, not confirmation.
