What GHK-Cu is

GHK-Cu is a very small peptide that carries a copper atom, found naturally in your blood. Levels are high when you're young and fall as you age. It is supplied as an analytical-grade reference material for laboratory research.

What it does — in plain terms

GHK-Cu acts like a repair-and-maintenance signal for skin. In lab studies it appears to tell skin cells to make more collagen, clean up damaged tissue, and close wounds — the upkeep jobs the body does less of as it gets older. That's why it is one of the most-studied peptides in skin science and shows up across so much anti-aging and wound-healing research.

Here's where GHK-Cu actually shows up in the published research:

Collagen production in skin
Wound healing
Skin repair and anti-aging models
Switching specific genes on and off (gene expression)
