Compounded tirzepatide doses: how the ladder climbs

Tirzepatide is started low and raised in steps. The approved Zepbound label sets 6 doses, 2.5 mg to 15 mg, with at least 4 weeks on each before the next. Below is what each rung is, when the label lets you reach it, and which ones it names as doses to stay on. A compounded vial has no label of its own, so this is the approved product’s schedule, the one every dose page here refers to.

Looking for prices rather than the schedule? What each dose costs across sellers, and which sellers raise the price as you climb, is on price by dose. Each dose below also has its own page with the sellers that price it.

The ladder, rung by rung

1. 2.5 mg · 2.5 mg is the first rung of the Zepbound label's schedule, the dose every patient starts on, taken once weekly for weeks 1 to 4. The label treats it as a dose for getting started, not one to stay on, so a seller whose price climbs with the dose charges its lowest figure here, and the month that matters is the one at the dose you settle on.
2. 5 mg · 5 mg is the second of 6 rungs of the Zepbound label's schedule. It is one of the label's maintenance doses (5, 10 or 15 mg), reached from week 5 at the earliest. A prescriber may keep you here or move on to 7.5 mg after at least 4 more weeks.
3. 7.5 mg · 7.5 mg is the third of 6 rungs of the Zepbound label's schedule, a step on the way up from 5 mg to 10 mg, taken for at least four weeks, weeks 9 to 12 at the earliest. The label does not name it as a dose to stay on; its maintenance doses are 5, 10 or 15 mg.
4. 10 mg · 10 mg is the fourth of 6 rungs of the Zepbound label's schedule. It is one of the label's maintenance doses (5, 10 or 15 mg), reached from week 13 at the earliest. A prescriber may keep you here or move on to 12.5 mg after at least 4 more weeks.
5. 12.5 mg · 12.5 mg is the fifth of 6 rungs of the Zepbound label's schedule, a step on the way up from 10 mg to 15 mg, taken for at least four weeks, weeks 17 to 20 at the earliest. The label does not name it as a dose to stay on; its maintenance doses are 5, 10 or 15 mg.
6. 15 mg · 15 mg is the top rung of the Zepbound label's schedule. It is one of the label's maintenance doses (5, 10 or 15 mg), reached from week 21 at the earliest. It is also the highest dose the label allows.

How many sellers price each dose

218 sellers charge one price at every dose, so they are counted on all 6 dose pages. The 45 whose advertised figure is an entry price that rises as the dose does are left off the dose pages (a starting price is valid at the starting dose only) and are set out ladder by ladder on price by dose.
