TB-500 99.0% Purity — Just The ProductCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum / Discord channel. The original poster claimed a lab tested Just The Product's TB-500, reporting 98.951% purity via HPLC and a quantity of 10.79mg 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.
