Which links were paid for, and which were never

Do we earn money from links?

Yes, from some. When an order follows certain links, a company shares revenue with us. We mark every commercial link the same way, paid or not, so they look alike to a search crawler. Every outbound link opens in a new tab.

How can you tell the two kinds of link apart?

Commercial links carry rel nofollow sponsored noopener. Those are the supplier's certificate index and its published certificate walkthrough.

Public documents carry rel noopener only. Those are the research records we cite and the regulator's page. The markup tells them apart, not just the wording.

What didn't the money touch?

The money decides where a link sits, and nothing else. It didn't touch any column, any result, or any question we ask. No row was bought, and when the seller table goes up, no row will be for sale.

Which rule does this follow?

We follow the US Federal Trade Commission's endorsement guidance, written as questions and answers: the Federal Trade Commission endorsement guidance. More about us is on the publisher behind this.

Where does this site stop?

We ask one question about a container: did anyone test what was inside, and publish the result? We report what a record examined and which way the result went. We report what a vendor document says, in its own words.

We say nothing about what any material does to a person. This compound has no approved human use and is research-grade material. None of this is medical advice or an instruction to do anything.
