How we check prices

Where a price comes from

Only three kinds of pages count: the program's own pricing or help pages, the drug maker's self-pay or savings pages, and government pages such as FDA and CMS. Prices quoted in reviews, news or ads are not used.

For every number we keep the exact sentence it came from, the page address and the date we read it. Open any row in the table to see them.

What a row's cost includes

The program's membership fee, any one-time fee such as a first visit, and the medication at the lowest dose that has a published price. When a program sends you to another channel for the medication, such as the maker's self-pay pharmacy, we use that channel's published price. Introductory prices are shown next to the regular price, not instead of it.

Makers sell a "month" of a weekly injection as four doses, which lasts 28 days. Lilly's own page says "Month is defined as 28-days and 4 single-dose vials". So 52 weeks take 13 fills, not 12, and we count 13.

How rows are ranked

By the total cost of the first 52 weeks at the starting dose, lowest first, and by nothing else. A row is ranked only when every part of its cost is published. Rows missing a part are listed separately as not ranked, with what is missing.

How often we check

We re-check every price every Monday. Any price we have not re-checked for more than 7 days is marked in the table.

What we leave out

• Compounded semaglutide or tirzepatide. FDA: However, compounded drugs are not FDA approved.fda.gov, Sep 27, 2026
• Programs whose operating company received an FDA warning letter about GLP-1 products, while that letter is unresolved.
• Supplements and products sold as "GLP-1 support".

The year-one ledger

The ledger on the home page adds up the first 52 weeks of published prices at one dose. It does not model dose changes, price changes or insurance. Treat it as a comparison of published prices, not a quote.
