Overview
GHK-Cu is a naturally occurring copper-binding tripeptide. Unlike most peptides in this library, it appears widely in topical cosmetic products, and is also studied for wound healing and skin remodeling.
How It's Thought to Work
GHK-Cu is thought to influence collagen and elastin production and modulate genes involved in tissue repair and inflammation.
What the Research Says
There is topical/cosmetic research and preclinical wound-healing research. Injectable use is far less studied and less regulated.
Regulatory & Legal Status
Topical GHK-Cu is common in regulated cosmetics. Injectable 'research chemical' forms are not FDA-approved for human use.
Safety Considerations
Topical cosmetic use is generally considered well tolerated; injectable use is unregulated. Consult a qualified clinician.
