GHK-Cu Copper Peptide Therapy

GHK-Cu is a naturally occurring copper-binding peptide first discovered in human plasma in 1973. The "GHK" refers to its three amino acid sequence (glycyl-L-histidyl-L-lysine), and the "Cu" refers to its tightly bound copper ion — the combination that makes it biologically active.

Your body produces GHK-Cu naturally — but levels decline significantly with age. By your 60s, you have roughly one third of the GHK-Cu you had at 20. This decline correlates closely with visible signs of aging skin and slower tissue repair.

GHK-Cu has been studied for over 50 years, appearing in everything from clinical wound-healing research to high-end topical skincare. The injectable form delivers it systemically — not just to the skin surface, but throughout your body.

GHK-Cu supports skin and tissue health through several pathways:

• Collagen and elastin synthesis — supports the structural proteins that keep skin firm, resilient, and elastic
• Antioxidant activity — copper is a critical cofactor for enzymes that protect against oxidative stress
• Skin remodeling — supports the natural turnover and renewal of skin tissue
• Hair follicle support — studied role in supporting healthy hair follicles
• Anti-inflammatory effects — helps regulate inflammatory signals associated with aging skin
• Wound healing — well-documented role in supporting tissue repair

GHK-Cu is typically administered as a subcutaneous injection. Dosing varies based on goals and can be adjusted throughout your protocol. Your 10 mg / mL vial provides flexibility across typical dosing ranges.

Timing is flexible — most patients dose in the evening, though this is not a requirement. GHK-Cu works through tissue remodeling, which takes time, so consistency across an 8–12 week course typically produces the best results.

GHK-Cu is commonly used as part of an ongoing aesthetic protocol — many patients cycle on and off throughout the year, often timing courses around in-office aesthetic treatments.
