Our reconstitute peptides calculator takes all the guesswork out of dosing by handling every conversion in one simple interface.
Just enter:
  1. Vial strength (mg) – the total peptide in your vial

  2. Diluent volume (mL) – how much bacteriostatic water you’re adding

  3. Desired dose (mcg) – your target microgram amount

Hit “Calculate,” and our tool instantly returns the exact mL (and—if you’re using an insulin syringe—units) you need to draw up.

How It Works Behind the Scenes
  • Convert mcg to mg: We divide your mcg dose by 1,000 so it matches the mg/mL concentration.

  • Calculate solution concentration: We divide the vial strength (mg) by the diluent volume (mL) to find mg per mL.

  • Determine injection volume: We divide the desired dose (mg) by the concentration (mg/mL) to get the precise mL to inject.

  • Syringe units (optional): We multiply the mL result by 100 (1 mL = 100 units) for easy readings on insulin syringes.

Whether you’re double-checking your math or learning the formula step-by-step, our reconstitution calculator mirrors the manual process exactly—ensuring you always know how to reconstitute peptides safely. Try it now and see how fast and error-free dosing can be!
