GHK-Cu
Copper peptide complex for tissue regeneration and skin health.
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
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.
Investigated Pathways
Proposed Mechanism
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.
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
Evidence is primarily from in vitro cell studies and animal models. Human data is limited or absent.

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.

PubMed →Pharmacokinetics
Bioavailability indicates how much of the compound reaches systemic circulation. Peak plasma is when blood levels are highest. Half-life determines dosing frequency — compounds with short half-lives require more frequent dosing to maintain therapeutic levels.
The volume of distribution reflects how widely the compound distributes into tissues. A higher Vd means the compound concentrates in tissues rather than staying in plasma.
Receptor Binding Profile
Delivers bioavailable copper to tissues, activating copper-dependent enzymes
Stimulates collagen and elastin synthesis in fibroblasts
Promotes healthy tissue remodeling by balancing matrix metalloproteinase activity
Promotes angiogenesis for improved tissue perfusion
Modulates over 30% of human genome toward a younger expression profile
Side Effects & Adverse Events
- Mild skin irritation with topical use
- Injection site redness (SubQ)
- Temporary skin darkening at application site (copper pigmentation)
- Nausea at high doses
- Copper toxicity at extreme doses (theoretical — far above research doses)
