TB-500 10mg Horizon documentation is labeled Batch B003. Vanguard COA V260804-17 001 lists the submitted lot as B003; Chameleon tracks the Vanguard-supported inventory internally as B003B to distinguish it from the prior B003 batch. Horizon support documentation and Vanguard identity, purity, measured mass, endotoxin, and heavy-metals results are posted. Vanguard sterility is pending.
