GHK-Cu is a copper peptide researched for skin regeneration, hair growth, wound healing, and anti-aging. Learn how it works, its benefits, uses, and dosing.
GHK-Cu Copper Peptide: Benefits, Uses, Mechanisms, and Typical Dosage Schedules
GHK-Cu, commonly referred to as copper peptide, is one of the most extensively studied peptides in regenerative and cosmetic research. Known for its role in skin health, wound healing, hair growth, and tissue repair, GHK-Cu has been used in scientific research for decades and remains a cornerstone peptide in dermatology and anti-aging applications.
This guide covers what GHK-Cu is, how it works, what it's used for, potential benefits, and commonly referenced dosage ranges based on published research and real-world protocols.

What Is GHK-Cu?
GHK-Cu is a naturally occurring tripeptide composed of three amino acids:
- Glycine
- Histidine
- Lysine
When bound to copper Cu²⁺, the peptide forms glycyl-L-histidyl-L-lysine copper complex, or GHK-Cu.
GHK was first identified in human plasma, saliva, and urine, with levels shown to decline with age. This decline is believed to be one reason interest in copper peptides has grown within longevity and regenerative research communities.

How GHK-Cu Works in the Body
GHK-Cu functions primarily as a cell signaling peptide. Rather than acting like a hormone or drug, it influences gene expression and cellular behavior.
Research suggests GHK-Cu may:
- Activate genes involved in tissue repair and remodeling
- Increase collagen and elastin synthesis
- Modulate inflammatory responses
- Support angiogenesis new blood vessel formation
- Enhance...
