Retatrutide 99.7% Purity — FinnrickCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested Finnrick's Retatrutide, reporting 99.7% purity via HPLC + FTIR, with a tested quantity of 33.4mg against a 30mg label (11.2% deviation). 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 should be treated as community signal, not confirmation.
