Peptide Calculator
Mix it right. Draw it right.
Pick your vial, enter how much bacteriostatic water you're adding and your target amount. You'll see exactly where to draw on the syringe.

This one comes pre-mixed, so there's no water to add. Enter the mg per mL printed on your vial label.

How the math works
- Concentration = amount in the vial ÷ water added.
- Volume to draw = target amount ÷ concentration.
- On a U-100 insulin syringe, 1 mL = 100 units, so units = volume × 100.
- For two-peptide blends, every draw contains both peptides in the same ratio as the vial.
This calculator is for educational and research purposes only and does the arithmetic only. It does not recommend any amount or protocol, and it is not medical advice. Double-check every number against your vial label, confirm which syringe you have, and talk with a qualified healthcare provider before using any compound. Many peptides are investigational and not approved for human use.
