Click-to-Dose Calculator

Enter your cartridge mg and target dose — get the exact click count on the Aevum pen. Advanced syringe-draw mode is available for users dosing manually from a cartridge.

Cartridge mg (total peptide load)

Printed on the cartridge label. Examples: BPC-157 = 20 mg, Retatrutide = 24 mg, NAD+ = 500 mg.

Target dose (mg)

The dose your protocol calls for, in milligrams. Sub-milligram doses are fine — the calculator converts to mcg automatically.

How the pen counts

Every Aevum cartridge delivers 60 clicks from full to empty. 15 clicks = one quarter of the cartridge. 30 clicks = half. Your dose ÷ (cartridge mg / 60) = the click count to dial. Match your protocol's dose to the click count, then turn the dose ring until you feel that many clicks.
