Overview

GHK-Cu is a naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) with a high affinity for copper ions. It is found naturally in human plasma, saliva, and urine, with concentrations declining significantly with age. This decline correlates with visible aging effects.

Research shows GHK-Cu stimulates collagen synthesis, promotes wound healing, has anti-inflammatory effects, and may even influence gene expression patterns — switching aging-related gene activity toward a healthier, younger profile. It is used both topically (skincare) and via injection (systemic anti-aging).

Frequently Asked Questions

What is GHK-Cu used for?
GHK-Cu (copper peptide) is primarily used for skin health, wound healing, and anti-aging. Research shows it stimulates collagen production, promotes hair growth, reduces inflammation, and may have anti-aging effects on skin and tissues.
How does GHK-Cu work for skin health?
GHK-Cu works by stimulating collagen and elastin production, promoting angiogenesis (new blood vessel formation), and activating stem cells. It also has antioxidant properties and helps remove damaged proteins from cells.
What is the typical GHK-Cu dosage?
For systemic effects, research dosages range from 1-3 mg per day via subcutaneous injection. For topical use, concentrations of 0.05-2% are common in serums and creams. Injectable forms are typically used 2-3 times weekly.
Can GHK-Cu be used topically?
Yes, GHK-Cu is highly effective when applied topically for skin benefits. Topical forms may be safer and more practical for cosmetic applications, though injectable forms may provide more systemic anti-aging effects.
Is GHK-Cu safe for research use?
GHK-Cu is generally considered safe with a good safety profile in research. It is naturally occurring in human plasma and tissues. Side effects are rare but may include skin irritation with topical use or injection site reactions.
