Compounded Tirzepatide is started low and stepped up gradually to limit nausea. The schedule runs 4 steps, from 2.5 mg to 15 mg, taken once a week and raised no faster than every four weeks. This is the brand schedule the compounded product copies — it holds no FDA-approved label of its own.
Compounded Tirzepatide dosing schedule
Compounded Tirzepatide has no FDA label, so there is no approved schedule of its own. Prescribers generally copy the brand ladder below, and the dose you draw depends on your pharmacy's concentration.

Enter your start date to see the exact dates your dose steps up — and when to reorder so you don't run out mid-titration. Built from the schedule above.
Reorder tip: a vial or pen typically covers ~4 weeks, so request your next fill about a week before you run out to avoid a gap during titration. This calendar is the standard label schedule — your prescriber may titrate slower for tolerability. General information, not medical advice.
What if you miss a dose?
No FDA label sets a missed-dose rule for Compounded Tirzepatide. The brand labels for the same medicine say — Zepbound: Inject the missed dose as soon as possible within 4 days (96 hours) of the missed day. If more than 4 days have passed, skip it and inject on your usual day. Two doses must be at least 3 days (72 hours) apart. Ask your prescriber which to follow, and never take two doses to catch up.
FAQ about Compounded Tirzepatide dosage
Is there an FDA-approved dose of Compounded Tirzepatide?
No. Compounded Tirzepatide is not an FDA-approved product, so no label sets its doses. Prescribers generally follow the brand schedule for the same medicine, and your pharmacy sets the concentration.
How do I measure a dose of Compounded Tirzepatide from a vial?
The dose is prescribed in milligrams but drawn in syringe units, and how many units make a milligram depends on the concentration printed on your vial label. Two pharmacies can supply different concentrations, so a units figure from one vial does not carry over to another. Confirm the draw with the dispensing pharmacist.
Always follow your prescriber's specific dosing instructions over generic guides. Full medical disclaimer.
If you take a compounded version drawn from a vial rather than a fixed-dose pen, your dose is prescribed in milligrams but measured in syringe units — and the conversion depends on your vial's concentration. See tirzepatide dosage in units for the concentration-by-concentration chart.
