Why this page exists
Peptide prices vary wildly between vendors — sometimes by 3x or more for the exact same compound at the same purity. Vendors use different quantity sizes to obscure comparisons. PeptidePrices normalizes every mg-denominated listing to a 10mg equivalent so you can compare unlike vial sizes on the same basis.
How we rank: Only in-stock listings are shown. Prices are deduplicated per vendor (cheapest variant only). Non-normalized listings (missing quantity data) are excluded. See our full methodology.
