Retatrutide 99.4% Purity — Hong Kong Lejian BiotechnologyCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested Lejian Biotech's retatrutide, showing 99.404% purity via HPLC and a quantity of 22.09mg for a 20mg label. However, the lab's signature is not directly verifiable from this source, and the image has passed through at least one re-share. This should be treated as community signal, not confirmation.
