I found a public batch report for TB-500 with independent lab results, including 99.805{a48505b7a92a5d64fa947b6701e2877576ce853b374f7be6d82c62f5ee4ca6d5} purity and 10.72 mg content, but it is for the 10mg batch rather than the 5mg listing. The product page itself contains general testing/traceability claims, but I did not find a batch-specific COA for the 5mg vial.
