Peptide calculators and free tools

Small calculators for reading prices and certificates of analysis. They only do arithmetic on what you enter, or look up public data. They do not judge a product or a shop, and none of them gives dosing or usage advice.

• Price per mg calculator

  Pack price, vials, mg per vial, VAT and shipping: the unit price and the price per mg, for one listing or two side by side.

• Price check against today’s market

  Where a quoted price sits among today’s in-stock offers for the same compound, from the live catalog.

• Purity-adjusted price calculator

  The price per mg of actual peptide, from the purity and net peptide content a certificate of analysis states.

• Peptide mass calculator

  Formula, monoisotopic and average mass and charge-state m/z from a sequence, for checking a CoA’s mass-spec line.
