Claims people make
Peptide Fact Checks reviews narrow claims one at a time. A claim only becomes public when it has a grade, verdict, source list, and last-reviewed date.

- cognition
Regulatory context
Legal status, product claims, and approved-use context can vary by market, so claims need source-specific review.
What to watch
Cognition claims should be read narrowly and should not replace clinician guidance for neurological or psychiatric concerns.
