What is GHK-Cu?
GHK-Cu is a copper-binding tripeptide that occurs naturally in human plasma and declines with age. It is widely used as an ingredient in topical skincare and is studied for tissue-remodeling applications.
Topical cosmetic use is common and broadly available. Injectable forms are a different matter and are under separate regulatory consideration in 2026.
How it is thought to work
GHK-Cu is studied for roles in collagen production, wound healing, and tissue remodeling, and for its copper-carrying activity, which is relevant to several repair processes.
What the research shows
There is a reasonable body of laboratory and topical research, particularly for skin. Evidence for injectable use is more limited, and routes of administration are not interchangeable.
We summarize published research and do not make therapeutic promises. A licensed provider can evaluate whether any therapy is appropriate for you. Treat any source promising guaranteed results with skepticism.
Studied uses
- Skin quality and repair research
- Hair-follicle support studies
- Tissue-remodeling interest
Legal status in 2026
Topical GHK-Cu is common in cosmetics. Injectable GHK-Cu is not an approved drug and is among the peptides set for separate federal review, with a consultation expected by early 2027 rather than at the July 2026 meeting.
Injectable routes are prescription-only where permitted and should never come from unregulated suppliers.
How to access GHK-Cu legitimately
For topical use, GHK-Cu is widely available in skincare. For any injectable use, a licensed provider can advise on suitability and, where permitted, prescribe through a licensed compounding pharmacy.
