About PeptideCalc

Free calculators for the arithmetic of peptide vials, with every step shown.

Why this site exists

Turning a vial label, a volume of water and a dose into a line on a syringe takes three steps of arithmetic, and a slip in any of them (mg for mcg, the wrong syringe, a misplaced decimal) can mean a dose that is ten or a thousand times off. Many calculators online give an answer without showing how they got it. PeptideCalc shows the working for every result, so you can check it yourself.

What we do and don't do

  • We do: convert the numbers you enter into concentrations, volumes and syringe units, and explain the math.
  • We don't: sell peptides, recommend doses or products, or give medical advice.

How we check the math

Every formula is covered by an automated test suite with more than 520,000 checks. The methodology page lists the formulas, rounding rules and tests.

How the site is funded

PeptideCalc is free to use. If we ever add advertising or affiliate links, they will be labelled, and they will never change what a calculator outputs.
