🧬 What is GHK-Cu?

GHK-Cu is a naturally occurring copper complex of the tripeptide glycyl-L-histidyl-L-lysine. It's found in human plasma, saliva, and urine.

Research Areas

• Skin quality — Collagen, elastin, firmness
• Wound healing — Accelerated repair
• Hair health — Follicle support, thickness
• Anti-inflammatory — Reduces inflammation
• Antioxidant — Activates protective enzymes

How It Works

• Collagen remodeling — Stimulates new collagen + organizes structure
• Growth factors — Upregulates VEGF, FGF, NGF
• Gene expression — Activates 4,000+ genes, suppresses 1,000+
• SOD activation — Boosts antioxidant defenses

✨ Expected Benefits

Skin (4-12 weeks)

• Improved skin texture and tone
• Reduced fine lines
• Better skin elasticity
• Faster wound healing
• Reduced hyperpigmentation

Hair (8-16 weeks)

• May increase hair follicle size
• Improved hair thickness
• Support for hair growth cycle

General Anti-Aging

• Antioxidant protection
• Reduced inflammation
• Tissue repair support

💉 Application Methods

1. Topical Serums (Most Common)

• Apply 1-3% GHK-Cu serum to face
• Morning and/or evening
• Can layer with other skincare
• Good for localized anti-aging

2. Injectable (Systemic)

Injectable

• Injection site irritation (mild)
• Rarely: headache, fatigue

Topical

• Rare skin sensitivity
• Possible irritation if combined with strong actives

🔗 Synergistic Combinations

For Skin

• GHK-Cu + Retinol — Both stimulate collagen
• GHK-Cu + Vitamin C — Antioxidant support
• GHK-Cu + Microneedling — Enhanced penetration

For Hair

• GHK-Cu + TB-500 — Cell migration + growth factors
• GHK-Cu + Minoxidil — Different mechanisms

For Anti-Aging Stack

• GHK-Cu + CJC/Ipamorelin — GH peptides for systemic support
