How we check GLP-1 prices

Every price on GLP Chart is read from the program's own pricing page, every week, and saved as a dated receipt. The price you see is the all-in monthly cost. Last full read: November 4.

1. We read the seller's own page

   Every week a script opens each program's own pricing page in a real browser and records every dollar figure with the row, column and plan it sits under, so a $149 monthly price is never confused with $149 for three months.

2. We keep a receipt

   Each read is saved as a dated receipt in our repository: the page address, the figures and where on the page each one was. A price can only change on the site when a receipt shows it.

3. We print the all-in monthly price

   The price on the chart is what a month costs you: membership, medication and any required visit or lab fee added together. A prepaid plan is shown as its monthly equivalent next to the total you pay up front. A first-month or sale price is labelled as one and shown beside the regular price.

4. We date every price

   The Checked date only moves when a full weekly read ran. A seller that blocks automated reads keeps its last checked date, shown on its row, until we read it again in a normal browser. Dates are New York time.

5. We check sales every Monday

   A sale stays on the site only while the seller's own page still shows it. When the banner is gone, the regular price returns at the next build.

6. We publish the data

   Each month the weekly reads are rolled into the GLP-1 price index, with a CSV and JSON download under a CC BY 4.0 licence. Corrections are logged in public.
