WHAT THE HEADLINE DOES NOT SAY

Four limits that belong beside the score.

A printed code is not a successful laboratory lookup.

Purity scope

The certificate excludes salts and sugars from its impurity peak list.

Separate endotoxin record

The supplier links an endotoxin PDF; it is not included in this coverage score.

COMPOUND IQ VERDICT

Useful document evidence, with a lot boundary.

4/7 describes the reviewed PDF, not company quality or human-use safety. Current inventory and laboratory authentication remain unconfirmed.

Lot-specificAuthentication unresolvedNo known affiliation

SOURCE DOCUMENTS
