About The Retatrutide File

Retatrutide is an investigational drug: no regulator anywhere has approved it. That one fact shapes everything on this site. We report where the drug stands on the day we check, what the trials found, who reported each number and what nobody knows yet.

What we cover

• What retatrutide is and how it acts on the body
• Trial results, with the placebo or comparator figure beside each one
• Side effects, by trial and by dose
• The doses trials tested, reported as facts about those trials
• How it compares with approved medicines such as tirzepatide and semaglutide
• The approval timeline, and the cost and coverage outlook
• The legal ways to get it today: clinical trials and Lilly's expanded access program

What we don't cover

• How to mix, measure or inject anything
• Reviews or rankings of sellers. We don't name sellers or link to them.
• Personal medical advice. Talk with a licensed clinician about your own care.

How we check

We go to primary sources first: journal papers, ClinicalTrials.gov records, the FDA and other regulators, and company filings and releases. Each source is labeled for what it is. A number from a peer-reviewed paper is marked as one. A number that so far appears only in a Lilly press release is marked "company press release, not yet peer reviewed" until a paper backs it.

Every time-sensitive fact carries a date. Each page shows when it was published and when we last checked it, ends with a list of its sources and keeps a dated record of its changes. When we get something wrong, the correction goes into that record with its date. The status rail on every page comes from one file that we check against the sources on the date it shows.

The byline on every page is the Retatrutide File desk. We don't invent experts or credentials, and no page claims a reviewer it didn't have.

Money and independence

We don't sell anything. There are no affiliate links, no ads for sellers and no sponsored pages. We are not affiliated with Eli Lilly and Company or with any seller of retatrutide or any other drug.
