What Is GHK-Cu?
What Is It?
GHK-Cu is a naturally occurring copper peptide found in human blood, saliva, and urine. It has been studied since the 1970s for its wide range of effects on healing, tissue repair, and cellular health. One of the more well-researched peptides in this library.
How Does It Work?
Copper is essential for many of the body’s repair processes. GHK-Cu appears to act as a delivery system — carrying copper directly to sites where repair work is happening and activating healing signals like collagen production. Think of it like giving the repair crew both the tools and the materials they need.
