Frequently asked

How much does PT-141 cost?
About $24–$60 per vial, depending on vial size. Compare the same size across vendors.
Why do PT-141 prices vary so much?
Vial sizes differ, so always compare the same vial size across vendors. Batch testing, stock, and pack discounts move the true cost too — see what "Verified" means.
How are PT-141 vendors verified?
A vendor earns a Verified badge only after independent batch testing (HPLC purity + mass-spec identity) checks out against its COA. Verification is never for sale.
