The Maylene toolkit
Dosage calculator.
Your product. Your strength. A clear conversion between milligrams and pen clicks, in either direction.
Make the conversion.
Choose your product
Enter your value
Enter either value. The other updates automatically.
Ready when you are.
Enter milligrams or clicks to see the matching amount here.
Based on the published values for matching pens. Check your pen’s instructions. This tool does not choose a dose.
Conversion is for one 500mg pen. The two-pen box contains 1000mg in total.
Three simple steps
Know what the numbers mean.
This is a conversion reference. It does not select an amount or recommend a treatment.
- 01
Match your pen
Select the product and its labelled content. Different strengths can have different conversions.
- 02
Enter one value
Type an amount in mg or a number of clicks. For blends, only the published reference points are available.
- 03
Check the reference
Read the conversion alongside the instructions for your exact pen. Fractional clicks are arithmetic results, not selectable dial settings.
What happens when I select a bundle?
Each pen keeps its own strength and conversion. Choose a component pen to calculate it individually; the total mg across a bundle is not a pen strength.
Why are some values unavailable?
Glow, Wolverine and the Retatrutide + Cagrilintide blend use a limited set of published reference points. Values between these points are not estimated. We do not have a confirmed conversion for Somatropin.
Where do the conversions come from?
The values were checked against the published reference for these pens on 5 October 2026. They are a reference, not independent device calibration. Always check the instructions supplied with your exact pen.
