TB-500 certificate of analysis

This listing has a published certificate: LC-MS identity and UV purity, with the lot number and the testing laboratory named. Each is also in the COA library. Where a size lists more than one lot, the lot number on the vial's label says which certificate applies.

10mg	TB10VAS0126	>99.2%	Feb 20, 2026

Each lot number opens its certificate (PDF). Issued by AxisPharm, LLC and provided by our supplier (where the certificates come from). Endotoxin (LAL), where the lab reported it, is printed on the certificate.

Shipping

Orders ship from the USA. Lyophilized solids are stable at ambient temperature in transit — moisture, not brief warmth, is the storage risk — so the emphasis is on sealing rather than cold packs. Free US shipping on orders over $200. Full details on the shipping page.
