This COA was extracted from a community forum, claiming a lab tested Anonymous STG's TB-500. The original poster reported 99.712% purity via HPLC, with a tested quantity of 12.42mg. However, the lab's signature is not directly verifiable, 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.
- chain-of-custody gap
