What it is
GHK is a naturally occurring tripeptide described in the scientific literature as a small peptide found in human plasma and studied by researchers for its copper-binding properties and its role in signaling related to tissue remodeling. It is closely related to its copper complex form and has been examined primarily in laboratory research models.
This page is provided for educational purposes only. It does not describe dosing, does not make treatment or outcome claims, and does not present GHK as a therapy for any condition. Whether any peptide is appropriate for an individual is a determination made only by a licensed provider following a confidential intake and review.
How it works
In the research literature, GHK is characterized as a copper-binding tripeptide studied for its interaction with signaling pathways associated with tissue remodeling and cellular processes in laboratory models. Investigators have described these properties within research settings rather than as clinical outcome claims.
Mechanistic descriptions in the literature are drawn from laboratory and early-stage research and should not be interpreted as evidence of clinical benefit. The relationship between any described mechanism and real-world outcomes in people has not been established here and remains a matter for qualified researchers and licensed providers to evaluate.

Frequently asked questions
What is GHK?
GHK is a naturally occurring copper-binding tripeptide studied in research on cellular signaling and tissue remodeling. This page describes it for educational purposes only and makes no treatment or outcome claims.
How is GHK different from GHK-Cu?
GHK refers to the tripeptide itself, while GHK-Cu refers to its copper complex form. Both are studied in research settings. This page discusses GHK for educational purposes only and makes no comparative claims of effectiveness.
Does this page tell me how to use GHK?
No. This page contains no dosing information and no usage instructions. Whether any peptide is appropriate for an individual is determined only by a licensed provider after a confidential intake.
Where do the research claims come from?
The research summary on this page links to a primary source record for this compound, such as its public NIH database entry, where applicable. This page is educational only and is not a substitute for advice from a licensed provider.
