Peptide Reconstitution Calculator

Peptide calculator

Step through your vial setup, target dose, and schedule to see syringe marks, approximate doses per vial, and how long a vial might last at a given frequency. For research and educational use only.

Start from example:

Vial setup

Peptide amount in vial (check the label)

Bacteriostatic water added (mL)

Dose & schedule

Your target dose per injection

Injections per week (for vial duration estimate)

/ week

Syringe capacity (typically 1 mL for insulin syringes)

Units marked on syringe barrel (typically 100)

units

Step 3 · Dose, syringe mark & vial duration

Concentration: 2.500 mg/mL (2500 mcg/mL)
Volume for dose: 0.100 mL
Syringe units to draw: 10.0 (on a 100-unit scale)
Approx. doses per vial: 20.0
Vial duration at 3 /week: 6.7 weeks (47 days)
Quick duration bands:
~6.7 weeks~1.7 months

These calculations are simplified and assume even distribution after reconstitution. They do not account for stability, injection technique, or any clinical decision-making. Always cross-check against primary research and professional guidance.
