GHK-Cu: The Copper Peptide Transforming Skin Regeneration and Wound Healing Research

GHK-Cu stands out with its extensive research history and multifaceted effects. This naturally occurring copper-binding peptide has been studied for over four decades for wound healing, collagen production, and inflammatory modulation. Today, I'm excited to share the comprehensive science behind GHK-Cu.

Key Insight: GHK-Cu is a naturally occurring tripeptide (Gly-His-Lys) that binds copper ions, activating tissue repair mechanisms, stimulating collagen synthesis, and modulating inflammation—critical for skin regeneration and wound healing.

What Exactly is GHK-Cu?

GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring copper-binding peptide found in human plasma, saliva, and urine. Discovered by Dr. Loren Pickart in 1973, this tripeptide consists of glycine, histidine, and lysine with high affinity for copper ions.

The copper-peptide complex gives GHK-Cu its biological activity. Plasma levels decline with age, from ~200 ng/ml at age 20 to ~80 ng/ml by age 60, correlating with reduced tissue repair capacity and visible aging signs.

Discovery and Development

Dr. Loren Pickart discovered GHK-Cu investigating why younger plasma had greater regenerative properties. Over 40 years of research has examined wound healing, skin regeneration, hair growth, and anti-inflammatory properties.

How It Works: Mechanisms of Action

Primary Mechanisms of Action

Collagen and Elastin Stimulation

GHK-Cu stimulates collagen synthesis by activating genes in fibroblasts, increasing collagen type I and III production. It also stimulates elastin production for skin elasticity.

Growth Factor Modulation

GHK-Cu influences multiple growth factors: VEGF for blood vessels, TGF-β for wound healing, and IGF-1 for cellular growth—orchestrating comprehensive tissue regeneration.
