GHK-Cu
Copper peptide complex for tissue regeneration and skin health.
2 mg/day (standard topical/SubQ dose)
Key Benefits
shown to increase collagen production by up to 70% in fibroblast cultures, improving skin firmness and joint integrity
accelerates tissue repair by activating growth factors and remodeling extracellular matrix proteins
upregulates superoxide dismutase and other antioxidant enzymes, reducing oxidative damage at the cellular level
modulates expression of over 30% of the human genome, reversing aging-associated gene patterns toward a younger profile
Recommended Injection Sites
Optimal injection locations for GHK-Cu based on its route (Subcutaneous or topical) and pharmacokinetic profile.
Tap a glowing zone on the body map to highlight the matching site card — or tap a card to activate the zone.
Tap a zone to inject
Primary research route for skin studies. Dissolve in carrier (DMSO/saline blend or cosmetic vehicle) and apply directly to target tissue.
For systemic research protocols. Standard SubQ technique applies.
Alternative SubQ site for systemic administration when abdomen is unavailable.
For topical use, apply to clean dry skin. For SubQ, rotate abdominal quadrants to prevent copper accumulation at a single site.
- IV administration without clinical supervision
- Injection directly into joint space without guidance
Active Signaling Pathway
GHK-Cu penetrates to the dermis where it activates fibroblasts via the SPARC gene and TGF-β1 pathway, triggering collagen and elastin synthesis. Its most remarkable property is modulating expression of over 30% of the human genome.

Scientific Background
Mechanism of Action
GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex) is a naturally occurring tripeptide found in human plasma, saliva, and urine. It binds copper(II) with high affinity and acts as a potent modulator of gene expression — studies show it can up-regulate over 30 genes involved in tissue repair and down-regulate genes associated with inflammation and cancer progression.
Clinical Context
GHK-Cu levels in human plasma decline from ~200 ng/mL at age 20 to ~80 ng/mL by age 60, correlating with reduced wound healing capacity and skin quality. Topical application has been validated in multiple clinical trials for reducing fine lines, improving skin density, and accelerating wound closure.
Research Highlights
- Loren Pickart's foundational research (1970s–2000s) established GHK-Cu as a key wound-healing and tissue-remodeling signal
- Shown to increase collagen synthesis by up to 70% in fibroblast cultures
- 2014 genome analysis revealed GHK-Cu modulates expression of 31.2% of the human genome — one of the broadest gene-regulatory effects of any known peptide
- Demonstrated neuroprotective effects in models of Parkinson's and Alzheimer's disease via antioxidant gene upregulation
Storage & Reconstitution
Topical application common for skin research. For systemic studies, subcutaneous injection is standard.
