GHK-Cu (Glycyl-L-histidyl-L-lysine copper) is a naturally occurring tripeptide-copper complex originally isolated from human plasma. It is a foundational research molecule known for its diverse roles in tissue regeneration, DNA repair, and antioxidant defense.

Core Biological Functions

• Copper Carrier Signaling: GHK-Cu acts as a specialized transport system, delivering copper ions into cells to activate essential enzymes like lysyl oxidase (for collagen cross-linking) and superoxide dismutase (for antioxidant protection).
• Gene Expression Modulation: Research indicates that the GHK peptide can modulate over 4,000 human genes, essentially resetting them to a more regenerative and "youthful" state.
• ECM Remodeling: It stimulates the synthesis of collagen, elastin, and glycosaminoglycans, which are the structural building blocks of the skin and connective tissues.
• Anti-Inflammatory Properties: It suppresses the production of pro-inflammatory cytokines and free radicals, helping to manage oxidative stress and cellular damage.

Research Indications

• Dermatological Repair: Extensively studied for its ability to increase skin thickness, improve elasticity, and reduce the appearance of fine lines and hyperpigmentation.
• Wound and Bone Healing: Demonstrated efficacy in experimental models for accelerating the repair of skin, bone tissue, and even gastric lining.
• Hair Growth: Investigated for its potential to enlarge hair follicles and stimulate hair growth by improving scalp health and circulation.
• Neuroprotection: Emerging research explores its role in protecting nerve cells and supporting cognitive health by reducing neuroinflammation.

Technical Specification Summary

Status and Safety (2026)

• Regulatory Status: While widely used in high-end cosmetic formulations, injectable or high-concentration GHK-Cu is not FDA-approved for human internal use. It is primarily categorized as a laboratory research chemical.
• Storage: The molecule is stable but should be stored at -20°C for long-term preservation, protected from light and moisture to prevent oxidation of the copper complex.

Medical Caution: GHK-Cu is intended for research and laboratory use only. It is not for human or veterinary consumption. All scientific findings are based on experimental and clinical research models and do not constitute medical advice.
