Corrections policy

GLP Observer corrects mistakes in the open. GLP-1 prices change often: when a source changes, we update the number, the verified-on date and the price-change log, and we never silently rewrite history. If you see a price that no longer matches its source, tell us and we re-check it against the original page.

Report a price

Email corrections@glp.observer with the page, the price you saw and a link to the official source. We only change a price after we load the source ourselves.

What counts as a correction?

Two different things. A price change is when a manufacturer or program changes what it charges; that is news, and it goes in the price-change log with the date and the source. An error is when we got something wrong: a misread price, a wrong dose tier, a stale date or a broken source link. Errors get a visible note on the page they affected.

How fast do you re-check?

We re-load the source page, save a fresh copy and compare it with the number we published. If the source confirms the report, the fix ships with the next build and the verified-on date changes. If the source doesn’t confirm it, we keep the published number and its date. The full process is on the editorial policy and methodology pages.

How corrections appear

• The table and prose are updated with the new verified-on date.
• Dated changes are added to the price-change log and RSS feed.
• Errors on our side (not price changes) are noted at the bottom of the affected page.

What a correction won’t do

We don’t remove a dated entry from the price-change log because a price moved again, and we don’t backfill a price we never saw on a live page. Reconstructed months in the price index stay labeled as reconstructed. If a manufacturer disputes a number, we publish what its own page says, with the date.
