About 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 has been studied for its remarkable ability to influence the expression of over 4,000 human genes — broadly shifting expression patterns toward tissue remodeling, repair, and regeneration. GHK-Cu is one of the most extensively studied peptides in skin biology, wound healing, and tissue remodeling research.

GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring tripeptide-copper complex found in plasma, saliva, and urine, declining with age. It functions as a biological signal that activates tissue remodeling at multiple levels: stimulates collagen I, III, and decorin synthesis; promotes dermatan sulfate proteoglycan production; increases VEGF for angiogenesis; attracts macrophages and mast cells; modulates metalloproteinase activity (both synthesis and inhibition); delivers copper to cells for superoxide dismutase and other cuproenzymes; and modulates expression of 4,000+ genes (32% up, 68% down), broadly resetting aged fibroblasts toward a healthier gene expression profile.

Key takeaways
-
Research score 8/10
1,300+ published studies in the dataset
-
Evidence tier: Emerging
Emerging — Topical applications have human clinical data (cosmetic studies). Injectable use has limited human data but extensive cell culture and animal data. Gene expression data is robust and published in peer-reviewed journals. The naturally occurring status and decades of topical use support safety.
-
Reality tier: Established
1,300+ studies. Human skin data (collagen, elasticity). Modulates 4,000+ genes. Plasma levels decline 60% with aging.

Storage and handling
Lyophilised powder: Room temp or refrigerated
After reconstitution: Refrigerate, use within 30 days
Safety and limitations
Studied for: Skin rejuvenation, Wound healing, Hair growth, Collagen synthesis, Tissue remodeling
Reported onset: Skin improvements visible in 2-4 weeks; wound healing effects within days
Reported duration: 4-8 weeks; 1-2mg SC daily
Community reports: Injection site reactions (burning, stinging) are the #1 complaint but considered manageable. Users report smoother skin texture, improved tone within 4-6 weeks. Community tips: ice pre-injection, inject slowly, rotate sites. Contraindicated in Wilson's disease.

Questions about GHK-Cu
Questions and answers recorded for this product.
Yes. GHK-Cu is widely used in topical skincare products. The injectable form provides systemic distribution. MEIMX currently offers the lyophilized vial; topical formulations are planned.
Cu is the chemical symbol for copper. GHK-Cu is a tripeptide with a bound copper ion, which is essential for its biological activity.
Plasma GHK-Cu levels drop approximately 60% between ages 20 and 60, which correlates with declining tissue repair capacity and skin health.
