TB-500 99.5% Purity — JPCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum, with the original poster claiming a lab tested JP's TB-500. The report indicates 99.487% purity and a tested quantity of 11.19 mg, with a test date of 2025-09-01 (older, 6-12 months). 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.
