Peptide reconstitution calculator
Enter your vial strength, bacteriostatic water, and target dose. Get syringe units, concentration, and doses per vial — updated live as you type.
Peptide in vial
Start here — total peptide amount listed on the vial label.
mg
Common: BPC-157 (10 mg), Retatrutide (5–10 mg), NAD+ (500–1000 mg)
Bacteriostatic water
How much water you add when reconstituting the vial.
mL
Typical: 2–3 mL for most peptides, 5 mL for larger vials like NAD+
Desired dose
Optional if you're not sure yet — leave blank to see common dose examples in results.
How to use this calculator
- 1. Enter vial strength — the total mg printed on the label (e.g. 5 mg).
- 2. Add water volume — how much bacteriostatic water you used to reconstitute (e.g. 3 mL).
- 3. Set your dose — e.g. 0.25 mg (250 mcg).
- 4. Read your draw — pull the syringe to the listed units for each dose.
