GHK-Cu
GHK-Cu (Copper Peptide GHK-Cu) is a naturally occurring tripeptide-copper complex found in human plasma, saliva, and urine. It declines significantly with age and has been extensively studied for its roles in skin regeneration, wound healing, and anti-aging.
Quick facts
- Half-life
- ~30 minutes
- Administration
- Topical / Subcutaneous injection
- Primary use
- Skin regeneration, wound healing, anti-aging
How it works
GHK-Cu stimulates collagen and elastin synthesis, promotes angiogenesis, and activates antioxidant defence systems. It also modulates gene expression — studies suggest it can reset gene expression patterns in aged cells towards a more youthful profile.
Reported benefits
- Increased collagen and elastin production
- Accelerated wound and skin healing
- Antioxidant and anti-inflammatory effects
- Potential gene expression modulation towards cellular rejuvenation
