Reconstitution Calculator

Peptide reconstitution calculator: mg, mL, and syringe units

Reconstitution is the step that determines concentration. Once concentration is clear, draw volume and U-100 syringe units become much easier to calculate, verify, and track.

Peptide reconstitution calculator formula

A peptide reconstitution calculator turns vial strength and liquid volume into concentration. That concentration is the basis for every later draw-volume calculation.

Step 1mg / mL = concentration
Step 2target mg / concentration = mL
Step 3mL x 100 = U-100 units

Example: a 5 mg vial mixed with 2 mL creates 2.5 mg/mL. A 250 mcg target amount is 0.25 mg. At 2.5 mg/mL, the draw volume is 0.1 mL, which equals 10 units on a U-100 syringe.

Why reconstitution volume changes everything

The same vial can produce different draw amounts depending on the amount of liquid added. If a 5 mg vial is mixed with 1 mL, the concentration is 5 mg/mL. If it is mixed with 2 mL, the concentration is 2.5 mg/mL. The target amount may be the same, but the draw volume changes.

What to save with every vial setup

  • Compound name and vial strength
  • Reconstitution volume
  • Calculated concentration
  • Target amount and draw volume
  • Date the vial was mixed or first logged

Why Vial AI connects reconstitution to logging

Reconstitution math is only half the job. The other half is preserving the setup so the next dose log has context. Vial AI is designed to connect scanning, calculation, protocol tracking, and dose history in one place.
