Retatrutide 99.7% Purity — Qingdao Saber Technology Pharma QstCertificate 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 99.72% purity and a quantity of 20.02mg (0.1% deviation from label). However, the lab's signature is not directly verifiable from this source, and the image has passed through at least one re-share, creating a chain-of-custody gap. This should be treated as community signal, not confirmation.
