Retatrutide 99.9% PurityCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested the product, reporting 99.858% purity for Retatrutide via HPLC with UV Detection Coupled with Mass Spectrometry, and a tested quantity of 22.31mg against a 20mg label (11.55% deviation). However, the lab's signature is not directly verifiable, and there is a chain-of-custody gap. This should be treated as community signal, not confirmation.
