PepCalc is an easy to use peptide calculator that determines how many milligrams (mg) of research peptides are in each unit or tick mark of an insulin or tuberculin (non-insulin) syringe after reconstitution. It’s the easiest way to accurately calculate peptide doses.


• Fully configurable - select syringe type, enter syringe volume, units, tick marks, quantity of peptide, volume of sterile or bacteriostatic water, and desired dose
• Last input values are remembered so they appear the next time the app is opened. No more unnecessary retyping!
• No signup required and no ads!

What’s New

Version 40.1.0

PepCalc is the easiest way to calculate accurate peptide doses. This release adds several features based on user feedback.

• Syringe type selection. To facilitate easier calculation you can now choose between U100 and U40 insulin syringes and then select a Unit count. PepCalc will automatically set the correct volume. No worries if you have a non-insulin syringe. You can pick tuberculin (non-insulin) from the dropdown to get complete control of the inputs.

• PepCalc has a memory! A common request we are excited to deliver - PepCalc now remembers the last values you entered. No more unnecessary retyping!

• Input bugs squashed. You can now enter numbers with or without leading zeros, i.e., .0 or 0.1

If your so frustrated that you might spend 5 dollars, look no further

Cured my frustrations within 15 seconds of using the app. Website calculators are trash and overly complicated

Works as promised but doesn’t adjust for screen size or font size. Have to fumble through to be able to see all the fields. Needs to adapt to zoom mode.
