GHK-Cu

CollagenSkin repair

GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma. Levels decline with age, and it is one of the most widely studied peptides in skin and wound-healing research.

What does it do?

Promotes collagen and elastin production, supporting tissue remodeling
Reduces fine lines, improves skin firmness and elasticity
Helps mitigate oxidative stress and inflammation at the cellular level
Studies suggest it may stimulate hair follicles and reduce hair loss

How does it work?

Binds copper ions to help regulate tissue repair and collagen remodeling genes
Upregulates antioxidant defenses and extracellular matrix remodeling pathways
Promotes angiogenesis and fibroblast activity at injury sites
Supports cellular regeneration through copper-dependent enzyme activation

How it's typically administered

Subcutaneous injectioncommon in research settings
Topical serum or creamwidest cosmetic use
Nasal sprayless common; limited absorption data
Oral capsulesbioavailability is debated
Intramuscular injectionunnecessary and higher risk

How it's typically dosed

Most common dose1–2 mg
Frequency5 days a week
Cycle duration10–12 weeks
