Peptide Dosage Calculator FAQs
Below you’ll find answers to the most common questions about using our peptide dosage calculator, reconstitution, and understanding syringe measurements — helping you get accurate results for research purposes.
What is a peptide dosage calculator?
A peptide dosage calculator is a tool that helps you determine the correct volume of reconstituted peptide solution to draw for a specific dose. By entering the amount of peptide in the vial, the volume of bacteriostatic water used, and your desired dose, the calculator automatically provides the concentration, required syringe units, and estimated doses per vial.
How do I use the peptide dosage calculator?
To use the calculator:
Enter the total amount of peptide in the vial (in milligrams).
Input the amount of bacteriostatic water you added (in milliliters).
Enter your desired dose and select the unit (mcg or mg).
Choose your syringe size.

What is bacteriostatic water and why is it used?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth. It’s commonly used to reconstitute peptides for research purposes, extending the shelf life of the solution compared to plain sterile water.
How do I calculate peptide concentration?
Peptide concentration is calculated by dividing the total amount of peptide (in micrograms) by the total volume of reconstitution solution (in milliliters). The calculator does this automatically, providing the concentration in μg/mL.
What does “units” mean on an insulin syringe?
On insulin syringes, 100 units = 1 mL. Smaller syringes (e.g., 0.3 mL or 0.5 mL) still have the same unit-to-mL ratio — they’re just shorter and marked differently. The calculator tells you exactly how many units to draw for your desired dose.
Can I use this calculator for any peptide?
Yes — the calculator works for any peptide where you know the amount in the vial and the reconstitution volume. Always ensure your calculations are for research purposes only and follow the guidelines provided by your supplier.
Is this calculator for medical use?
No. This tool is intended for research and educational purposes only. It is not a substitute for professional medical advice, diagnosis, or treatment.
