Price per mg: questions

Price per milligram is the displayed price divided by the total milligrams in the vial. A verified discount is used only where it is explicitly recorded. This normalises offers across sizes: a $19.80 10 mg vial is $1.98/mg, while a $30.00 20 mg vial is $1.50/mg.
How we verify prices

Automated price sources are scheduled daily; other sources are checked manually. Check the offer's last successful source timestamp. A code is shown when it is attached to an offer or affiliate link. The displayed price includes a discount only when that code is cart-verified and the discounted price is explicitly recorded; otherwise it is the vendor's listed price. Prices exclude shipping. Stock status is captured at the same time. Rankings are by displayed price, except that the labelled featured partner, LA Peptides, is pinned first; “Cheapest” always marks the lowest price. PeptideTech earns a commission when you buy through a link.
