SS-31 99.5% Purity — Allen Biotechnology Co AbcCertificate 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, but the lab's signature is NOT directly verifiable from this source — the image has passed through at least one re-share. The report indicates 99.492% purity via HPLC for SS-31, with a significant quantity deviation of +20.48% (60.24mg tested vs 50mg label). This is community signal, not confirmation, and there is a chain-of-custody gap.
