Retatrutide 99.9% Purity — HB PeptideCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested HB Peptide's Retatrutide, reporting 99.873% purity and a quantity of 20.50 mg for a 20mg label. The test is recent (under 3 months). However, the lab's signature is not directly verifiable, and there is a chain-of-custody gap, so this should be treated as community signal, not confirmation.
