Peptide Calculator
Free peptide dosage calculator and reconstitution calculator for research. Instantly calculate how many units to draw on a standard U-100 insulin syringe for precise peptide measurement.
Configuration
Amount of peptide powder in the vial.
Amount of bacteriostatic water mixed.
The dose you want to administer.
How the Peptide Calculator Works
Enter Vial Amount
Input the total peptide content in your vial (in mg). Common sizes are 5mg, 10mg, or 15mg.
Add Water Amount
Specify how much bacteriostatic water you'll use for reconstitution. This determines your solution concentration.
Set Your Dose
Enter your desired dose in micrograms (mcg). The calculator shows exactly how many syringe units to draw.

Peptide Calculator FAQ
How do I use the peptide calculator?
Enter the peptide vial amount (in mg), the amount of bacteriostatic water you'll add (in ml), and your desired dose (in mcg). The calculator will show you exactly how many units to draw on a U-100 insulin syringe.
What is peptide reconstitution?
Peptide reconstitution is the process of dissolving lyophilized (freeze-dried) peptide powder in a sterile solvent, typically bacteriostatic water. This creates a stable solution that can be accurately measured for research purposes.
How much bacteriostatic water should I add to my peptide?
A common ratio is 2ml of bacteriostatic water per 5mg of peptide, but you can adjust based on your needs. More water means smaller doses per unit, which can be useful for precise micro-dosing. Our calculator works with any ratio you choose.
What is a U-100 insulin syringe?
A U-100 insulin syringe is calibrated so that 100 units equals 1ml. This is the most common syringe type used in peptide research because the unit markings allow for precise measurement of small volumes.
How do I calculate BPC-157 dosage?
For BPC-157, enter the vial size (typically 5mg), the amount of bacteriostatic water added, and your target dose. Common research doses range from 250-500mcg. The calculator will display the exact syringe units to draw.
How long does reconstituted peptide last?
When stored properly in a refrigerator at 2-8°C, most reconstituted peptides remain stable for 3-4 weeks. Keep them away from light and avoid repeated freezing and thawing.
