GHK-Cu is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.

GHK-Cu (GHK-Cu (Copper Peptide)) is a Tripeptide-copper complex. Naturally occurring peptide found in human plasma, saliva, and urine; levels decline significantly with age from 200 ng/mL at age 20 to 80 ng/mL by age 60. It is researched for skin rejuvenation, wound healing, anti-aging, hair growth, collagen production, anti-inflammatory effects. Common dosages range from 1-3 mg (injectable), topical formulations vary administered once daily.

What Is GHK-Cu?

GHK-Cu (GHK-Cu (Copper Peptide)) is a Tripeptide-copper complex. Naturally occurring peptide found in human plasma, saliva, and urine; levels decline significantly with age from 200 ng/mL at age 20 to 80 ng/mL by age 60. Also known as GHK-Cu, Copper Tripeptide-1, Loren Pickart peptide, it has been studied for its potential effects on skin rejuvenation, wound healing, anti-aging, hair growth, collagen production, anti-inflammatory effects.

The only peptide documented to modulate over 4,000 human genes, with the unique property of declining naturally with age — making supplementation a form of restoring youthful gene expression patterns rather than introducing something foreign. In the research community, GHK-Cu has gained attention for its distinctive profile.

How Does GHK-Cu Work?

GHK-Cu modulates expression of over 4,000 human genes — activating those involved in tissue remodeling, antioxidant defense, and stem cell biology while suppressing genes associated with inflammation and tissue destruction. It promotes collagen and elastin synthesis, attracts immune cells to injury sites, and supports angiogenesis through metalloproteinase regulation.

This multi-pathway activity helps explain why GHK-Cu shows potential across several different applications.

What Does the Research Say About GHK-Cu?

Over 1,000 published studies document wound healing, skin remodeling, and anti-aging properties. The peptide modulates 4,000+ human genes and has strong evidence for collagen/elastin synthesis, anti-inflammatory activity, and hair growth promotion.

Researchers should consult the latest peer-reviewed literature for the most current findings.

What Is the Recommended GHK-Cu Dosage?

Standard GHK-Cu dosing: 1-3 mg (injectable), topical formulations vary, administered once daily via subcutaneous injection or topical application.

Half-life: approximately 2-4 hours. Cycle length: 4-12 weeks.
