Totals come from the same optimizer as our comparison tool: each vendor's cheapest way to supply the amount, with its multi-vial and mix-and-match discounts, the discount codes we hold for that vendor, and shipping to the US. Vendors reach each amount with whatever vial sizes they sell, and a vendor without a matching size may ship slightly more. Codes marked "first order only" assume a first order. "Per mg" is for the 100mg total. Confirm the final price at checkout. *Testing marked with an asterisk is present on some batches, not all.
