TB-500 99.4% Purity — Qingdao Sigma ChemicalCertificate of Analysis · Independent third-party lab result
This COA was extracted from a Telegram channel, which is a low-trust intake source. The report claims Janoshik tested QSC's TB-500 (batch White) at 99.402% purity, with a tested quantity of 11.02mg. Customers should cross-reference this finding against third-party-lab tests of the same batch where available, as the channel itself is a verification bottleneck.
