Naturally occurring copper-binding tripeptide popular for skin remodeling, hair, and regenerative aesthetics.
How to picture it
Imagine damaged tissue as a construction site that forgot the blueprint. GHK is a tiny three-amino-acid carrier that grabs copper and delivers it where repair enzymes need it. In research it also shifts large gene sets toward collagen production, antioxidant defense, calmer inflammation, and matrix remodeling. Picture a site manager who both brings the right metal tool (copper) and posts updated instructions on the wall (gene expression). That's a repair-signal plus copper-delivery package — one of the better-characterized peptides for skin and soft-tissue remodeling science.
Research focus & benefits
- Collagen and matrix remodeling gene research
- Wound healing and skin-quality studies
- Copper-delivery and antioxidant pathway interest
- Anti-inflammatory remodeling signals in literature

Overview
GHK-Cu is a copper complex of the tripeptide GHK found in human plasma, saliva, and urine; levels decline with age. Topical cosmetic use is common; injectable research use appears in regenerative and hair communities. It has a friendlier reputation than many systemic research peptides.
Mechanism
Gene-expression modulation related to wound repair, antioxidant defense, collagen/elastin synthesis, and anti-inflammatory signaling; copper delivery may support enzymatic processes.
Research uses
- Wound healing
- Skin remodeling and cosmetic science
- Hair follicle research
- Anti-inflammatory gene studies
Research dosing notes
Topical serums are the mainstream path. Injectable research dosing is less standardized and should not be improvised.
Half-life / kinetics
Short; topical vs injectable kinetics differ
Common research routes
Reported considerations
- Skin irritation topically
- Copper overload theoretical risk with excess systemic use
- Blue-green discoloration of topicals
Contraindications / cautions
- Wilson disease / copper disorders
- Broken skin with unsterile products
- Pregnancy caution
Common research stacks
- BPC-157
- TB-500
- Microneedling + topical GHK-Cu (cosmetic contexts)
Legal / access note
Widely used in cosmetics; injectable medical status varies. Cosmetic topicals are not the same as sterile injectable research products.
