What is GHK-Cu?

GHK-Cu is a naturally occurring copper-binding tripeptide present in human plasma that declines with age. It is common in both skin and regenerative research.

In the research literature, GHK-Cu is most commonly studied for collagen production, skin remodeling and antioxidant activity.

Buying GHK-Cu safely

Always ask for a batch-specific Certificate of Analysis (COA) covering purity (HPLC) and identity (mass spec), and favour suppliers with independent, third-party testing and transparent shipping and return policies. Research peptides may be regulated where you live — you are responsible for complying with local laws.
