GHK-Cu

GHK‑Cu – Copper Tripeptide for Regeneration and Skin Biology Research

GHK‑Cu (glycyl‑L‑histidyl‑L‑lysine–copper) is a small human plasma tripeptide that tightly binds copper(II), studied for its role in tissue remodeling, wound healing, and protection against oxidative and inflammatory damage. As a regenerative signaling molecule, GHK‑Cu has been shown in preclinical and clinical models to stimulate collagen and extracellular‑matrix production, support angiogenesis, and modulate gene expression linked to repair and aging.

Key features

• Skin and tissue repair: GHK‑Cu promotes wound closure, dermal remodeling, and improved skin thickness, firmness, and elasticity while reducing fine lines, wrinkles, and photodamage in clinical and experimental settings.

• Anti‑inflammatory and antioxidant actions: The peptide reduces pro‑inflammatory cytokines (e.g., TNF‑α, IL‑6), lowers oxidative stress, and supports antioxidant defenses through pathways such as NF‑κB and p38 MAPK modulation.

• Gene‑expression modulation: GHK‑Cu has been reported to influence thousands of genes, upregulating those involved in repair, matrix synthesis, and stem‑cell function while downregulating genes tied to inflammation and tissue breakdown.

• Multi‑tissue relevance: Beyond skin, studies show beneficial effects on lung, liver, intestinal lining, bone, and nervous tissue, supporting its use in diverse regenerative and anti‑aging research paradigms.

  
  

Research applications

GHK‑Cu is employed in experimental systems exploring:

• Dermatologic and cosmetic biology, including wound healing, scar remodeling, photoaging, pigment irregularities, and dermal‑matrix restoration.

• Inflammation and organ protection, such as models of lung injury, ulcerative colitis, hepatic toxicity, and chronic wounds where both anti‑inflammatory and pro‑repair effects are evaluated.

• Hair‑follicle and scalp research, with data indicating improvements in hair density, hair shaft diameter, and follicular health in androgenetic‑alopecia and transplant‑support models.

• Aging, stem‑cell biology, and neuroprotection, where GHK‑Cu is investigated for its impact on gene networks related to cellular senescence, stem‑cell activity, and neuronal survival.

  
  

Recommended handling

• For controlled laboratory research use only, by qualified professionals.

• Store in a cool, dry environment away from light; follow institutional SOPs for peptide storage, reconstitution, aliquoting, and disposal.

• Investigators should consult current literature when designing dosing, delivery route (topical, systemic, in vitro), and outcome measures for skin, tissue, or systemic models.
