Don't Shoot the Calculator! We handle the maths. You handle the common sense. PeppyCalc provides calculations, not medical advice. Educational and entertainment use only. Consult a qualified professional.
Selecting a peptide fills this automatically. You can still edit it.
Use the diluent specified for your product.

2Turn the dialTurn the knob until your number lines up with the arrow.
3Confirm the penMake sure your actual device is U-100 and uses the same dial range.
Valid pen setting: 0 of 60 units maximum.
Turn the dial until your calculated number reaches the fixed indicator in the dose window.
Need fewer pen units?
If your product instructions allow a more concentrated reconstitution, you can use less diluent and recalculate.
PeppyCalc will not change the value automatically.
Needle and zero are on the left. Read the dose at the needle-side edge of the black rubber stopper.
