TB-500 95.5% Purity — Shenzhen Maide TechnologyCertificate 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 95.479% purity for TB-500 and a quantity of 10.65mg against a 10mg label. However, the lab's signature is not directly verifiable from this source, and the image has passed through at least one re-share, indicating a chain-of-custody gap. This should be treated as community signal, not confirmation.
