This calculator is provided for reference only and does not constitute medical or dosing advice. Always follow the guidance of a licensed healthcare professional and the product's certificate of analysis.
How the Calculator Works
Four quick inputs give you an exact syringe reading.
Choose Your Dose
Pick the amount you intend to draw per injection. Use one of the preset pills or type a custom value if yours isn't listed.
Enter Vial Strength
Select how much peptide is in the vial you're working with — this is usually printed right on the label.
Add Your Water Volume
Enter how much bacteriostatic water was used to reconstitute the vial. More water means a larger, more easily measured draw volume.
Read the Syringe
The calculator instantly shows the concentration, the exact syringe unit mark, and how many doses the vial contains.
Frequently Asked Questions
What are peptides used for?
Peptides are short chains of amino acids that act as signaling molecules in the body. They're widely studied for applications spanning recovery, metabolism, skin health, and more — this page is educational and explains how the calculator works, not guidance on use.
How do I calculate a peptide dose?
You need three numbers: how much peptide is in the vial, how much water was added to reconstitute it, and how much you intend to draw. This calculator turns those three inputs into a syringe reading automatically.
How much water should I mix with a peptide?
That depends on the concentration you want. Adding more water spreads the same amount of peptide over a larger volume, giving you a bigger — and easier to measure — draw per dose. Always follow the reconstitution instructions that came with your specific vial.
How is concentration calculated?
Concentration is the vial strength divided by the water volume added. For example, a 10mg vial mixed with 2mL of water gives a concentration of 5mg/mL. The calculator does this automatically and carries it through to your syringe reading.
How do I convert a volume into syringe units?
Standard insulin syringes are marked in "units" rather than milliliters. On a common U-100 syringe, 100 units equals 1mL. This calculator handles that conversion for you based on your inputs.
Is this calculator medical advice?
No. This tool performs arithmetic only — it converts the numbers you enter into a syringe measurement. It does not recommend a dose and isn't a substitute for guidance from a licensed healthcare professional.
