What this site is
A free site that grades 72 compounds by how well they are proven in people. Every claim links to the study or agency page it came from.
No ads. No sponsors. No affiliate links. Nobody pays to be listed or removed. It is not medical advice.

The audit log: every check and correction, dated →
How the grades work
- A: Strong human proof. Big trials in people, and it worked.
- B: Some human proof. Small, early or mixed results in people.
- C: Animals and lab only. Looks good in rats or in a dish. Not proven in people.
- D: Forum talk. No published proof. Forum talk, or trials that never reported results.
One grade per compound, for the use people talk about, not for every use.
Quoting us
- Call it Worked in Rats, and link the page you used.
- Keep the grade and the catch together. A grade alone can mislead.
- Grades change when new studies come out. Check the date in the audit log.
- The grade cards and badges are free to use with a link back.
When we get it wrong
We fix it and say so. Every correction stays in the audit log with its date. You can follow the log as a feed.
