Four assertions, made by every listing, before a single document is opened

Who is making the claims?

The seller. A claim comes printed on the container or typed above the price. It costs nothing to make. Four claims show up on almost every listing, and we describe them in general terms, never quoted from a named seller.

Is it what the listing says?

The listing says the container holds the compound it names. That's an identity claim, made by the seller. It stands until a measurement checks it.

Is there as much as the label says?

The label claims an amount inside. That's a content claim. We print no amount, because we have no source for one. So it stays a claim.

Is it as clean as stated?

The listing says the material is clean. That's a purity claim. Clean in a listing is a sentence. Clean on a document is a measured reading. They're not the same thing.

Where did it come from?

The listing hints at where the material came from. That's an origin claim, and usually the softest of the four. It's suggested more than stated, so we treat it as implied, not shown.

Claimed, not measured

The seller makes all four claims. We have no evidence about any seller's containers, and we contradict none of them. We only say what kind of statement each one is.

See the document line behind each assertion, or go back to claimed against found.

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.
