Price per mg: questions

Price per milligram is the price after code divided by the total milligrams in the vial. It 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

Prices are read from each vendor's product page weekly, converted to the price after any listed code, and shown before shipping. Stock status is captured at the same time. Rankings are by price only. PeptideTech earns a commission when you buy through a link; it never changes the order.
