GHK-Cu Nasal Spray

$50.00

GHK-Cu Copper Tripeptide-1 or GHK-Cu is lab-made to replicate the naturally occurring peptide found in plasma, saliva, and wound fluid. It contains three amino acids bound to a copper ion and has an affinity for skin tissue. 

GHK-Cu is used in research settings to understand: 

  • Tissue Repair Pathways: GHK-Cu is being studied for its potential to activate genes and proteins that support collagen production and healthy cell turnover
  • Inflammation Balance: Researchers examine how GHK-Cu may modulate signals that regulate inflammation, helping scientists understand its role in maintaining a balanced immune response.
  • Oxidative Stress Protection: Scientists are investigating GHK-Cu’s role in antioxidant pathways that help protect cells from oxygen species and environmental stressors.

Our 10 mL GHK-Cu peptide nasal spray contains 90 mg total peptide, releasing a precise 1.1 mg amount for research purposes only. Each bottle contains 80 sprays.

What is GHK-Cu?

GHK-Cu is a small three-amino-acid peptide (glycine, histidine, lysine) bound to a copper ion. Because it appears naturally in tissues involved in healing, scientists study GHK-Cu for its potential roles in cell repair, inflammation balance, and antioxidant signaling.

Topical and intradermal GHK-Cu are the most common applications in cosmetic research; the intranasal form remains experimental. This format is provided for research only. No human clinical evidence exists on the safety, effectiveness, or dosing of intranasal GHK-Cu.

  • Absence of contaminants (microbial, heavy metals, solvents)

Lab testing ensures that the material provided is consistent, high-quality, and suitable for research purposes.

Research Related to GHK-Cu

Here are some highlighted studies related to GHK-Cu. Please keep in mind that while these studies are promising, copper peptide isn’t approved as a drug or dietary supplement, meaning its use remains limited to research.

Tissue Repair and Wound Healing Pathways

Many studies have looked at GHK-Cu’s affinity for tissue repair. GHK-Cu signals skin cells called fibroblasts to produce more collagen — the protein that gives skin its strength and firmness, acting like scaffolding in a building. 

Because GHK-Cu helps to build this “scaffolding” and supports other repair processes, researchers are looking into how this peptide can help with cuts, damaged skin, and other injuries heal faster and better [1, 2]

Skin Biology Research

Lab and skin studies suggest GHK-Cu helps skin rebuild its support structure by increasing collagen and elastin, and by helping enzymes that break down and rebuild the matrix stay in balance, which aligns with its use in wound-healing and anti‑aging products. 

Topical GHK-Cu creams have been shown to help make skin firmer, thicker, and smoother over a few months, and in at least one study, they boosted collagen more than vitamin C or retinoic acid creams [1,3].

Anti-Inflammatory & Antioxidant Signaling

GHK-Cu helps cells handle “chemical stress” and calm down inflammation in several ways. 

Studies have shown that GHK-Cu can reduce harmful molecules called reactive oxygen species (ROS) and boost the cell’s own protective mechanisms. Some research also suggests it can prevent excess iron from leaking from storage proteins and reduce damage to fats in cell membranes, which may help protect tissues like the brain from oxidative damage [4, 5].
