Peptide Calculator

Calculate reconstitution and dosing for your peptides.

How This Works

When you reconstitute a peptide, you're mixing the powder with bacteriostatic water. The amount of water you add determines the concentration. This calculator helps you figure out exactly how many units to draw in your syringe to get your desired dose. Remember: units are not your dose — they're just a measurement on the syringe.

How to Read Your Syringe

On a standard 100-unit insulin syringe, each small line = 1 unit. The "units" result tells you how many lines to fill to.

Example: 12.5 units = fill to halfway between the 12 and 13 line.

Common Conversions

  • • 1 mg = 1,000 mcg
  • • 1 mL = 100 units (insulin syringe)
  • • 0.1 mL = 10 units
