Neurotoxin Reconstitution Calculator

Interactive dilution calculator for all 6 FDA-approved neurotoxins. Select your product, vial size, and saline volume to calculate concentration, units per 0.1mL, and practical yield.

Supported Products

Botox (OnabotulinumtoxinA) — Allergan/AbbVie

Vial sizes: 50U, 100U. Most common dilution: 2.5mL per 100U vial = 4.0 U per 0.1mL.

Storage: Refrigerate 2-8°C. Use within 24 hours after reconstitution. Do not freeze.

Dysport (AbobotulinumtoxinA) — Galderma

Vial sizes: 300U, 500U. Most common dilution: 1.5mL per 300U vial = 20 U per 0.1mL.

Conversion: approximately 3 Dysport units = 1 Botox unit. Units are NOT interchangeable between products.

Xeomin (IncobotulinumtoxinA) — Merz

Vial sizes: 50U, 100U. Most common dilution: 2.5mL per 100U vial = 4.0 U per 0.1mL.

"Naked" neurotoxin — no complexing proteins. Room temperature storage OK up to 36 months before reconstitution.

Jeuveau (PrabotulinumtoxinA) — Evolus

Vial size: 100U. Most common dilution: 2.5mL per 100U vial = 4.0 U per 0.1mL.

Purpose-built for aesthetics. Marketed as #NEWTOX.

Daxxify (DaxibotulinumtoxinA-lanm) — Revance

Vial size: 100U. FDA-approved dilution: 0.6mL per 100U vial = 16.7 U per 0.1mL.

Longest-lasting neurotoxin (6-9 months). Room temperature storage OK before reconstitution. Uses novel peptide stabilizer.

Letybo (LetibotulinumtoxinA-jcdb) — Hugel/Evolus

Vial sizes: 50U, 100U. Most common dilution: 2.5mL per 100U vial = 4.0 U per 0.1mL.

Newest FDA-approved neurotoxin (2024). High purity, low protein load.

How to Use This Calculator

  1. Select your neurotoxin product.
  2. Choose your vial size.
  3. Enter or select the amount of saline you plan to add.
  4. View the resulting concentration (units per 0.1mL and units per 1mL).
  5. Review the practical yield estimate — how many usable units you'll actually get from the vial.
