What to look for on a TB-500 COA

A lot number that matches the vial in your hand, and a test date after that lot was made.
HPLC purity of 98% or higher, with mass-spec identity confirming it is TB-500.
A named lab, ideally ISO 17025 accredited, and endotoxin and sterility results for anything that will be injected.
A measured amount close to the label. Large gaps are a red flag.

Purity is HPLC area percent as reported by the lab; some reports confirm content and identity without a purity figure. Reports are the supplier’s published PDFs; we don’t test vials ourselves. See our methodology and affiliate disclosure.
