How the Calculation Works

Step 1: Set the Target Dose

Choose the amount of peptide, in milligrams (mg), for a single use. Enter this into the calculator, or use the custom field for an exact value.

Step 2: Enter Vial Strength

Enter the total amount of peptide in the vial. Common strengths include 1mg, 5mg, 10mg, and 15mg — or enter a specific amount if it isn't listed.

Step 3: Enter Water Added

Enter the volume of bacteriostatic water used to reconstitute the vial, in millilitres (mL). This determines the resulting concentration.

Step 4: Read the Draw Line

The calculator shows the concentration, doses per vial, and the equivalent draw line on a standard U-100 insulin syringe.

Frequently Asked Questions

How do I use the peptide reconstitution calculator?+
Select the target dose per use, the total peptide strength in your vial, and the amount of bacteriostatic water you added. The calculator works out the resulting concentration, how many doses the vial yields, and the equivalent draw line on a standard U-100 insulin syringe.
What syringe does the draw line assume?+
The syringe gauge assumes a standard U-100 insulin syringe, where 100 units equals 1mL. If you use a different syringe size, convert using the concentration (mg/mL) figure instead.
How is concentration calculated?+
Concentration (mg/mL) is the total peptide strength in the vial divided by the volume of water added. For example, a 5mg vial reconstituted with 2mL of water gives a concentration of 2.5mg/mL.
Why does more water mean a bigger draw volume for the same dose?+
Adding more water dilutes the peptide, lowering the concentration. A lower concentration means a larger volume is needed to reach the same target dose — which shows up as a longer draw line on the syringe.
What if my exact vial strength or dose isn’t listed?+
Use the custom input field under each column to enter any value directly — the calculator isn’t limited to the preset options.
Is this calculator a substitute for professional guidance?+
No. This tool is provided for research and laboratory reference only, to help estimate reconstitution math. It does not replace protocols established by a qualified professional or your organization’s research procedures.
