Selank 100.0% 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 99.958% purity via HPLC for Selank. The quantity tested was 10.85mg against a 10mg label, an 8.5% deviation. 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.
