What does the COA badge mean on Thymalin listings?

The vendor publishes certificates of analysis (lab reports) for its products on its own site. 0% of the in-stock offers above come from vendors that do. Check that a report exists for the exact product and lot you order: a COA shows what a lab measured for one batch, not a guarantee about the vial you receive.
