GHK-Cu Research Peptide
Copper-binding tripeptide studied for collagen synthesis, skin regeneration, and wound healing research
What is GHK-Cu?
GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. It was first isolated from human plasma albumin and has since become one of the most studied peptides in skin biology and regenerative research.
Researchers study GHK-Cu for its remarkable ability to stimulate collagen synthesis, promote wound healing, activate antioxidant defenses, and modulate gene expression related to tissue repair. Its copper-chelating properties are central to its biological activity in laboratory models.
מה זה פפטיד GHK-Cu
GHK-Cu הוא פפטיד טריפטיד טבעי הקושר נחושת, הנמצא בפלסמת הדם האנושית. חוקרים חוקרים אותו בשל יכולתו לעורר סינתזת קולגן, לקדם ריפוי פצעים ולהפעיל מנגנוני הגנה נגד חמצון ברקמות שונות.
Mechanism of Action
Collagen & Elastin Synthesis
GHK-Cu stimulates fibroblasts to produce collagen types I, III, and IV, as well as elastin and proteoglycans, which are essential structural proteins for skin and connective tissue integrity.
Antioxidant Defense Activation
The copper complex activates superoxide dismutase and other antioxidant enzymes, protecting cells from oxidative stress and free radical damage during tissue repair processes.
Gene Expression Modulation
GHK-Cu influences the expression of over 4,000 human genes, including those involved in tissue remodeling, anti-inflammatory pathways, and cellular repair mechanisms.
Angiogenesis & Wound Healing
Promotes new blood vessel formation and accelerates wound closure by stimulating keratinocyte migration, fibroblast proliferation, and growth factor production.
Research Areas Studied
Skin Regeneration
Studies examine collagen production, skin thickness, elasticity, and cellular renewal in laboratory models.
Wound Healing
Research focuses on wound closure rates, scar reduction, and tissue repair mechanisms.
Anti-Aging Research
Investigations into oxidative stress reduction, cellular senescence, and longevity-related gene expression.
Neuroprotection
Emerging studies on nerve regeneration, neuroprotective effects, and central nervous system repair pathways.
Half-Life Information
Short Half-Life: ~1-2 Hours
GHK-Cu has a relatively short plasma half-life of approximately 1-2 hours. However, its downstream effects on gene expression and collagen synthesis can persist significantly longer due to its influence on cellular signaling pathways.
The copper-chelating properties of GHK-Cu contribute to its stability in biological environments, and its effects on tissue remodeling can continue for days after administration in research models.
Storage Guidelines
Lyophilized (Powder) Storage
- Store at 2-8°C (refrigerated) for optimal stability
- Protect from light and moisture at all times
- Can be stored at -20°C for extended periods
- Shelf life: typically 24-36 months when properly stored
Reconstituted Solution Storage
- Store at 2-8°C immediately after reconstitution
- Protect from light using amber vials or foil wrap
- Use within 14-28 days depending on solvent used
- Do not freeze reconstituted solutions
Reconstitution Concept
GHK-Cu is supplied as a lyophilized powder requiring reconstitution with a sterile solvent before use in research applications. Proper technique preserves the copper-peptide complex integrity.
Select Appropriate Solvent
Sterile water or bacteriostatic water is recommended. Avoid acidic solvents that may disrupt the copper-peptide complex.
Add Solvent Slowly
Inject solvent down the side of the vial to minimize foaming and preserve the copper chelate structure.
Gentle Mixing
Swirl gently or roll the vial between hands. Never shake vigorously as this can disrupt the copper-peptide bond.
Verify Complete Dissolution
The solution should appear clear to slightly blue-tinted due to the copper complex. No visible particles should remain.
