Why Use a Free Peptide Calculator

A good peptide calculator saves you from manual math and shows your result in a way you can actually use at the bench.

Skip the manual math

Working out mg to mL by hand is easy to get wrong. A free peptide calculator does the same math instantly and shows you exactly where each number came from.

See your result on a real syringe scale

Instead of just a number, our tools show your draw volume on a visual syringe or pen so you know exactly where to draw to.

Free to use, nothing to sign up for

Every tool on this page is free and works without an account. Create a free account only if you want to save your results for later.

Which Peptide Tool Should You Use?

Each tool on this page is built for a different job. Here's how to pick the right one for what you're doing.

Mixing a peptide from a vial

If you're reconstituting a peptide with bacteriostatic water, start with the peptide dosage calculator. It covers vial size, water volume, and target dose for over 100 compounds.

Planning a research cycle

If you're setting up a full schedule with more than one compound, the protocol builder lets you pick compounds, set quantities, and lay out the whole cycle at once.

Using a Mounjaro pen

If you're working with a Mounjaro (tirzepatide) pen and counting clicks, the Mounjaro click chart turns your pen strength and dose into an exact click count.

Comparing semaglutide and tirzepatide

If you're trying to understand how a semaglutide dose compares to a tirzepatide dose, the conversion calculator shows an estimated range in either direction.
