Prepaid plans are where the money gets stuck

The pattern in complaints is consistent: a patient prepays during titration, does not tolerate the drug, and discovers the term is not refundable.

The sequencing that protects you is monthly billing until you have held a maintenance dose for a cycle, prepaid after.

What this changes for what you pay

Most developments in this category move one of three things: the price of the branded product, which programmes are operating, or what may lawfully be compounded. Very few change the prescription requirement, the pharmacy licensing framework or the clinical review behind a prescription.

The cheapest verified compounded route we track currently sits at $215 a month all-in at a 10 mg maintenance dose, about $2,580 for a first year. Where a development moves that figure, our tables move with it on the next build.

How to verify this yourself

Regulatory claims should be checked against the agency rather than against coverage of the agency. FDA publishes warning letters searchable by company name, a shortage database, and its compounding pages. Trial claims should be checked against the registry entry rather than a press release.

Every source behind this item is linked below, and where a story is still moving we say so rather than implying it is settled.

The failure mode this section guards against

Choosing a programme on a number that describes a different situation than yours. An entry price when you will hold maintenance. A medication figure when a membership applies. A promotional rate when you will renew.

Each error is small alone and they compound in one direction, which is why the cheapest-looking option in most published comparisons is the one most likely to be mis-stated. Priced correctly the cheapest verified route sits at $215 a month all-in at a 10 mg maintenance dose.

Why we publish the working rather than a verdict

A single recommendation reads better and acts worse, because it hides the weighting. Two readers with different maintenance doses, different coverage and different tolerance for commitment should not receive the same answer.

So the tables carry the inputs and every ranking states its sort key. Disagree with our weighting and you can take the file and weight it yourself — which is what publishing it is for.

The number most people get wrong

The month-six figure. Almost everyone budgets from the first month, which on tirzepatide describes four weeks at 2.5 mg — roughly 10 mg of active drug against the 40 mg a maintenance month delivers.

Ten of your first twelve months are spent at or near maintenance. A ranking sorted on the advertised month is sorting on about eight per cent of your year, and on a dose-scaled programme those are different numbers entirely.

Run the first-year calculator at the dose you expect to hold. It takes under a minute and it reorders the market for most people.

What a year of this actually looks like

Four weeks at 2.5 mg, four at 0.5 mg, four at 1 mg, four at 1.7 mg, then 10 mg for the remainder. Eight to twelve weeks of titration if nothing is repeated, and repeats are common rather than exceptional.

Budget two extra months at a lower tier and treat anything better as upside. Fix a weekly injection day, record dose and date, and diary the renewal date if an introductory rate applies — the reversion is where most complaints in this category begin.

What the head-to-head trial actually showed

SURMOUNT-5 randomised adults with obesity to tirzepatide or semaglutide and reported a larger mean reduction in body weight on tirzepatide over 72 weeks. It is the strongest direct comparison available and it is the reason many people arrive at this molecule specifically rather than at GLP-1 therapy in general.

Three caveats are worth carrying. A mean is not a prediction for an individual, and the distribution around it is wide. Trial participants received structured support most telehealth programmes do not replicate. And the trial compared maximum tolerated doses, which is a different question from what a given person will tolerate.

Read as a purchasing decision, it says the more expensive molecule does more on average. It does not say it will do more for you, and it says nothing about which programme should supply it.

Why titration is a pricing question

Tirzepatide is started at 2.5 mg weekly and increased in 2.5 mg steps at intervals of at least four weeks. The starter dose is a tolerance-building dose rather than a therapeutic one, and the gastrointestinal effects that cause most discontinuation cluster in the days after each increase.

Reaching a maintenance dose therefore takes at least eight to twelve weeks when nothing is repeated, and repeats are common rather than exceptional. Most of a first year is spent at or near maintenance, which is why every figure on this site is stated at 10 mg and why 12 of the 16 priced programmes holding one price across the ladder is a materially different offer from the rest.

The molecule, and why it costs more than semaglutide

Tirzepatide is a single peptide that activates two incretin receptors: GLP-1, which semaglutide also targets, and GIP, which it does not. Both receptors influence insulin secretion, gastric emptying and central appetite signalling, and the working hypothesis for the larger effect size is that engaging both produces effects the GLP-1 arm alone does not.

That dual action is also part of why it costs more to make. The peptide is longer and more structurally complex than semaglutide, the synthesis is harder, and the active pharmaceutical ingredient sells at a premium to compounding pharmacies. Across programmes carrying both molecules, tirzepatide typically runs forty to a hundred per cent above the same programme's semaglutide price.

The commercial consequence is that a compounded tirzepatide programme has less room to discount than a compounded semaglutide one. When a tirzepatide price looks dramatically below the market, the explanation is usually a promotional rate, a prepaid term or a starting dose rather than a cheaper supply chain.
