Pen click calculator
Mix into a 3 ml pen vial, then see how many clicks for your dose.

mL
Default 3 mL for a standard pen vial.
Common peptide pens use 60 clicks/mL — editable if yours differs.
Enter peptide, BAC, and dose to see clicks.

Dose volume exceeds BAC in the pen — check your numbers.
Exact clicks aren’t a whole number. Round to the nearest click (shown above), or adjust BAC / dose for a cleaner dial.
How it works
Potency = vial mg ÷ BAC ml (shown as mg/mL and mcg/mL).
Volume for dose = dose (mg) ÷ potency (mg/mL).
Clicks = volume (mL) × clicks per mL.
Example: 10 mg + 3 mL BAC → 3.333 mg/mL. Dose 250 mcg → 0.075 mL → 4.5 clicks at 60 clicks/mL (round to 4 or 5).
