Peptide Injector Pen Dosage Calculator

Use this calculator to find out exactly how many clicks of your peptide injection pen you need for your desired dose. Enter the total amount of peptide, the volume of bacteriostatic water used, and your target dose below.

For standard 60IU/Unit Peptide Pens and 3ml Cartridges.

Total milligrams of peptide in your vial
Millilitres of bacteriostatic water used to reconstitute
Your intended dose per injection in milligrams

How the Calculation Works

Concentration (mg/ml)

Divide the total peptide amount (mg) by the total water added (ml). Example: 30 mg ÷ 3 ml = 10 mg/ml.

Volume Per Dose (ml)

Divide your desired dose (mg) by the concentration (mg/ml). This gives the exact volume to inject.

Pen Clicks

Each click on your peptide pen delivers exactly 0.01 ml. Divide the volume per dose by 0.01 to get the number of clicks needed.
