We checked the human research behind 16 peptides. The question wasn’t just “is there a study?” It was “does that study support the pitch?” For each one: who took part, what was measured, and what actually changed.

An approval, a trial or a paper belongs to a particular substance and a particular use. None of it verifies the contents of a bottle sold online. This is an investigation of the claims, not a guide to taking them.
