Peptide Calculator

This calculator turns two numbers you already have — the milligrams in a research vial and the millilitres of bacteriostatic water added — into the concentration of the resulting solution in mg/mL, and optionally the volume that contains a given quantity of material. It is a laboratory preparation and record-keeping aid for researchers; it computes solutions, never anything about a subject.

Laboratory preparation tool

The easiest way to get reconstitution right: enter what's in the vial and how much bacteriostatic water you're adding, and get the exact concentration and measured volumes for your lab work.

One thing to understand before you calculate: this tool — and everything we sell — is for education and laboratory research. Researchers and labs use it to prepare and document research solutions. It isn't medical advice or dosing guidance, and nothing here is for human or veterinary consumption. Full details in our Terms of Service.

Everything this calculator returns describes a solution on a lab bench: milligrams of material, milliliters of solvent, the concentration that results. That's by design — it's an educational tool for researchers, and it offers no guidance about administering anything to anyone. What you do in your lab is governed by your institution's protocols and applicable law.
