The Verdict · Calculators
Three calculators that use real prices, not round numbers.
A dosage calculator that also tells you what the dose costs. A cost calculator that applies the intro step-ups and term commitments the headline rate leaves out. And a titration planner that prices the months you spend climbing to a maintenance dose. Every figure comes from the 499-provider roster behind our rulings, or from the FDA label it cites.
The tools
365 of the 499 providers we rule on publish a price for at least one molecule; 146 publish no semaglutide figure and 174 publish no tirzepatide figure. The calculators use the ones that do and name the ones that do not.

GLP-1 dose calculator
mg → units on an insulin syringe
Enter your weekly dose and the concentration printed on your vial; get the units to draw on a U-100 syringe, the whole label escalation ladder converted at that strength, and what a month of the medicine costs at the 365 providers publishing a price.

GLP-1 true cost calculator
what you pay at month 12, not what the sticker says
Advertised rates hide two things: intro rates that step up, and terms you cannot leave. This prices every provider over your own horizon with both applied, and names every row whose bill exceeds its headline.

GLP-1 titration schedule planner
how long the climb takes, and what it costs
The Wegovy and Zepbound escalation schedules week by week, mapped onto billing months — plus the cost of every month spent getting to a maintenance dose.

Where the numbers come from
Two sources, kept apart on purpose — and a guard that stops them drifting.
Prices — our roster
The same 499 provider records that drive every ruling on this site, with the conditions each provider attached to its own figure — “from”, annual terms, microdosed rates, intro months — modelled rather than discarded. A test asserts that every dollar figure the calculators use appears in the price the roster filed, and that every figure the roster filed appears in the calculators. A number in one and not the other fails the build.
Doses — the FDA labels
Escalation schedules are transcribed from the Wegovy (semaglutide) injection and Zepbound (tirzepatide) injection prescribing information on DailyMed, and each one carries the set id of the exact label document it came from. Compounded semaglutide and tirzepatide are not FDA-approved and have no label of their own; prescribers commonly titrate them against the brand schedule, and yours may not. None of this is a dosing instruction.
Then read the ruling
A calculator answers a number. The boards answer who to buy from.
