Retatrutide 99.5% 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 Homopeptide's Retatrutide, reporting 99.49% purity via HPLC and a quantity of 10.97mg against a 10mg label. However, the lab's signature is not directly verifiable, and the test is stale (over a year old). This should be treated as community signal, not confirmation.
