> A GHK-Cu FAQ answering 22 common copper-peptide questions — safety, collagen, hair, gene effects, and regulatory status — each answered directly from the cited research literature.

Twenty-two of the most-asked copper-peptide questions, each answered in two or three sentences and cited to the study behind the number.

## Definitions and mechanism

This GHK-Cu FAQ collects the questions people actually ask about the copper tripeptide and answers each from the published record.
