Peptide Calculator
Calculate precise peptide dosing with confidence. Our calculator helps you accurately determine syringe units based on peptide strength, desired dose and reconstitution volume.
Start CalculatingThree inputs, one exact answer
Tell us your dose, your vial strength and your diluent volume — we return the precise number of units to draw on a U-100 insulin syringe.
Enter your dose
Choose the amount of peptide you want per injection, in milligrams.
Enter vial strength & diluent
Add the total peptide in the vial and the volume of bacteriostatic water you reconstituted with.
Read your syringe units
We calculate the concentration and show exactly how far to draw on a U-100 syringe.
Accuracy is everything
Peptides are dosed in tiny volumes. A small miscalculation can mean a large difference in your actual dose.
Consistent results
Precise, repeatable dosing keeps your protocol steady from vial to vial.
Safety first
Knowing your exact concentration helps you avoid accidental under- or over-dosing.
No guesswork
Skip the mental math — the calculator handles concentration and unit conversion for you.
Built for calm precision
Reads in syringe units
Answers in the U-100 units marked on your insulin syringe — nothing to convert.
Instant & interactive
Adjust any value and the result — and the animated syringe — update in real time.
Works for any peptide
Enter custom strengths, doses and diluent volumes for any reconstitution.
