Peptide Dosage Calculator
Enter your vial size, bacteriostatic water volume, and desired dose. The calculator
instantly shows your concentration, exact volumes to draw, and how many injections
you’ll get from the vial.
How It Works
- Choose your peptide — select from the list to auto-fill vial size and water volume, or enter values manually.
- Verify vial size & water volume — auto-filled from the protocol but you can adjust if needed.
- Enter your desired dose — type the number and pick your unit (mcg, mg, or syringe units). Results update automatically.
- Read your results — concentration, all dose equivalents, and injections per vial appear instantly.
Understanding the Math
Concentration = Vial amount (mg) ÷ Water added (mL)
Volume to draw = Dose (mg) ÷ Concentration (mg/mL)
Syringe units = Volume (mL) × 100 (for a standard U-100 syringe)
