TB-500 99.6% Purity — CathyCertificate of Analysis · Independent third-party lab result
This COA was extracted from a community forum attachment. The original poster claimed a lab tested Cathy's TB-500 product, reporting 99.616% purity via HPLC and a 5.9% quantity overage (10.59mg tested vs 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. This should be treated as community signal, not confirmation.
