GHK-Cu

GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) research compound renowned in the literature for its role in skin remodeling and tissue regeneration. It is studied for its ability to remodel the dermal matrix—stimulating collagen, elastin, and glycosaminoglycan synthesis while modulating the metalloproteinases that govern controlled breakdown—as well as for its support of wound repair, angiogenesis, and antioxidant signaling. This makes it a cornerstone compound for researchers exploring aesthetic restoration and the biology of healthy, resilient tissue.
