Tell us what we got wrong.

We will get things wrong, a misread study, a stale number, a source we missed. Corrections are a feature here, not an embarrassment. Point us to it and we'll check it against the source, fix it, and date the change.

Send it over

One careful message beats ten vague ones. Link the source if you have it.

What's this about?

Which compound? (optional)

Your name (optional)

Message We read every message from a person. We don't reply to bots, pitches for link placement, or anyone selling vials.

Got it — your message is with us. Corrections with a source are actioned within a few days. If you left an email we'll reply there; if not, we can't, but we'll still act on it.

How a correction is handled

We check your claim against its original source, not against our own page. If you're right, we fix it and stamp the page with the change. If the source doesn't hold up, we'll tell you why. Either way, you hear back from a human.
