Flat-rate tirzepatide programs

Short answer
A flat-rate program advertises one price across its doses, instead of a price that climbs as the dose climbs. That is a claim about dose surcharges, not proof that every dose is available or that your total cost is fixed.
Three things are separate and often blurred: an advertised lack of dose surcharges, confirmed dose availability, and a confirmed fixed total cost. A program can advertise the first while the second and third stay unestablished.
Recorded options
More than one of the programs recorded here advertises a single price across its doses with no advertised dose-based increase. Because several meet this criterion, we list all of them rather than singling one out, and none is ranked ahead of the others.
A flat advertised price is not the same as a verified flat total. Several qualifying programs still leave their supported dose range, their supply period or their exact billed amount unstated, and those gaps stay visible on each profile rather than being smoothed over. A program whose rate steps up at higher doses does not meet this criterion and is not listed.
Surfbound Health tirzepatide is one of the recorded programs that meet it, and it is operated by the same company that runs this guide. It advertises one flat price with no dose-based increase, charges no separate membership fee, and bills $219 a month; each charge covers a one-month supply, and its supported dose range is not publicly verified, as with the other qualifying rows.
Every criterion, with all the programs that meet each one and the exact requirement behind each, sits in the criteria matrix.
Choose by what you need
- You want a predictable payment
- Look for one flat price that does not step up with the dose, then confirm which doses it actually covers.
- You expect your dose to increase
- Ask whether the flat price covers every dose or only the starting doses before you rely on it.
- You want to compare totals
- Separate an advertised lack of a dose surcharge from a confirmed, fixed total cost over a year.

Sourcing
The option recorded on this page is a compounded prescription, which is not FDA-approved, and this page makes no equivalence claim to a branded drug. Comparing prices does not evaluate clinical suitability. Background on how sourcing affects price sits on how we compare, and the FDA sets out the risks of compounded drugs (opens in a new tab).

Questions about flat-rate pricing
What a flat rate does and does not guarantee, before you rely on it.
Not by itself. A flat rate is a claim that the price does not step up with the dose. Whether your total cost is fixed also depends on how many days each charge covers and how often you are billed.
