Peptide Reconstitution Calculator
Calculate exactly how much bacteriostatic water to add and how far to pull your syringe for accurate peptide dosing. Enter your vial size, water volume, and desired dose.

How It Works
15 mg = 5,000 mcg total peptide
25,000 mcg ÷ 2 mL = 2500 mcg/mL concentration
3250 mcg ÷ 2500 mcg/mL = 0.100 mL
40.100 mL = 10.0 units on syringe
