40 / 300 clicks
Administering 4mg (40 clicks) every 3 days over 8 weeks requires 19 total administrations and approximately 3 pens. Each pen provides 7 doses at this dose level.
Insufficient pens — increase supply or reduce duration.

Retatrutide Dosage Calculator FAQ

What does this retatrutide planning tool calculate?

It converts a target dose into clicks for the 30mg pen, estimates how many administrations your plan includes, and shows how many pens the protocol will consume over time.

How many clicks are in the 30mg retatrutide pen?

The 30mg pen contains 300 clicks total, with each click delivering 0.1mg of retatrutide.

When do I need to split a dose into two injections?

The pen dial tops out at 60 clicks per administration (6mg). Any weekly dose above 6mg needs to be split across two injections in the same session.

Can this tool tell me how many pens I need for a multi-week protocol?

Yes. The calculator combines your target dose, administration frequency, and protocol duration to estimate how many full pens a plan will require.

What is the difference between this planning tool and the clicks chart?

The clicks chart is the quick lookup page for direct mg-to-click conversions. This planning tool also estimates total administrations, pens needed, and protocol duration.

Does this replace the full dosage guide?

No. This page handles the math. The dosage guide covers the broader Phase 3 titration schedule, escalation pace, and weekly target doses used in published retatrutide protocols.

Where do I check batch proof and pen specs?

Use the Retatrutide 30mg Pen product page for batch proof and product identity, or open the COA library for certificate files.
