Frequently asked

How much does Semaglutide cost?
About $45–$90 per vial, depending on vial size. Compare the same size across vendors.
Why do Semaglutide 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 Semaglutide 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.
