How it works

Work backward from your preferred units

The calculator converts your target amount to mg, converts preferred syringe units to mL, then estimates the concentration and total diluent volume needed to match those user-entered values.

Boundary

Measurement math, not instructions

Pepski does not tell anyone what to use, how much to use, how often to use it, or how to administer anything. The output is a record-keeping calculation only.
