Description
GHK-Cu (Glycyl-L-Histidyl-L-Lysine-Copper) is a naturally occurring copper-binding peptide found in human plasma, saliva, and urine that declines with age. It functions as a powerful signaling molecule influencing multiple cellular pathways, offering broad regenerative and protective benefits.
Skin Health & Anti-Aging
- Stimulates collagen and elastin production, improving skin firmness, elasticity, and reducing wrinkles.
- Enhances skin density, hydration, and texture, with clinical studies showing up to 30% improvement in elasticity and 25% reduction in wrinkle depth after 12 weeks of use.
- Reduces fine lines, hyperpigmentation, and photodamage while promoting keratinocyte proliferation.
- Accelerates wound healing and tissue repair, with research indicating 40–50% faster wound closure compared to controls.
Hair Growth & Scalp Health
- Promotes hair follicle stimulation and increases hair density and thickness.
- Extends the anagen (growth) phase of the hair cycle and improves scalp circulation.
- Reduces inflammation in the scalp environment, supporting healthier follicle function—particularly beneficial for androgenetic alopecia.
Tissue Repair & Regeneration
- Accelerates healing of skin, hair follicles, gastrointestinal tract, bone, and connective tissues.
- Enhances angiogenesis (new blood vessel formation), improving nutrient delivery to damaged areas.
- Restores replicative vitality to fibroblasts, even after radiation exposure.
Systemic & Cellular Benefits
- Modulates over 200 genes involved in tissue repair, inflammation, oxidative stress, and aging.
- Acts as a potent antioxidant, reducing reactive oxygen species (ROS) by up to 40%.
- Exhibits anti-inflammatory effects by suppressing pro-inflammatory cytokines (e.g., TNF-α, IL-1β) and NF-κB pathway activity.
- Supports neuroprotection and cognitive health, with preclinical evidence suggesting benefits in neurodegeneration and brain function.
Delivery & Safety
- Available in topical serums (0.5–2%), subcutaneous injections, and IV infusions.
- Generally safe with minimal adverse effects; rare side effects include mild irritation or allergic reactions (<2%).
- Contraindicated in Wilson’s disease, hemochromatosis, or copper metabolism disorders.
- Injectable forms should only be administered under professional supervision.
While preclinical and in vitro data are robust, human clinical trials are still emerging. For optimal results, GHK-Cu is best used as part of a holistic wellness protocol including nutrition, sleep, and lifestyle habits.
