Retatrutide 99.6% Purity — HomopeptideCertificate of Analysis · Independent third-party lab result
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 + MS for retatrutide. The tested quantity of 18.39mg significantly exceeded the 15mg label. The lab's signature is not directly verifiable, 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.
