Mechanism of Action
GHK-Cu (Gly-His-Lys:Copper) is an endogenous copper tripeptide with serum concentration that declines with age. Studies demonstrate multiple mechanisms: activation of matrix metalloproteinases (MMPs) for tissue remodeling, upregulation of growth factors (TGF-β, VEGF), modulation of ~4,000 human genes, and potent antioxidant and anti-inflammatory action.
Data based on available scientific literature. Protocol individualization depends on qualified professional assessment.
Applications Described in the Literature
- ✓Clinical studies in skin rejuvenation: increased collagen, elastin and glycosaminoglycans
- ✓Wound healing research: acceleration documented in animal and human models
- ✓Studies in hair growth: hair follicle activation and reduced loss
- ✓Neuroprotection investigations: human gene array data
- ✓COPD studies: improvement of inflammatory markers in genomic analyses

✓ DesbloqueadoProtocols Described in the Literature
GHK-Cu is extensively studied in topical formulations (creams, serums) and, in a more exploratory context, via subcutaneous or intradermal route. In cosmetology, concentrations of 0.5–3% are most documented in topical efficacy studies. Intradermal injections (mesotherapy) with GHK-Cu are described in rejuvenation literature, with frequency ranging from weekly to monthly.
Dose Ranges Observed in Studies
- ◆Topical use: efficacy studies used 0.5–3% concentrations in emollient formulations
- ◆Subcutaneous use: exploratory use literature refers to ranges of 1–2 mg per administration
- ◆Intradermal mesotherapy: described in reports with 0.1–0.5 mg per application point
- ◆Frequency: topical studies with daily use; injectable use described weekly to monthly
Effects Timeline (Literature)
Topical studies document subjective improvement in texture and hydration in 4–6 weeks. Measurable collagen increase by biopsy observed in 12-week studies. Hair growth effects documented in 3–6 months of continuous use. Gene array studies demonstrate detectable gene expression changes in 24–48h.
Documented Associations
- ↗BPC-157 and TB-500: plausibility for skin and soft tissue recovery with complementary mechanisms
- ↗Vitamin C: documented synergy in collagen synthesis studies
- ↗Retinoids: combination described in combined topical rejuvenation protocols
Monitoring Described in Studies
- ⊕Skin elasticity and hydration: assessed by cutometry in topical studies
- ⊕Dermal thickness: skin ultrasound described in 12-week studies
- ⊕Hair density: digital trichoscopy documented in hair loss studies
- ⊕Collagen markers: urinary hydroxyproline in remodeling studies
Clinical Observations from Studies
- ℹEndogenous molecule with broad safety profile in topical use based on decades of cosmetological studies
- ℹPleiotropic action via modulation of ~4,000 genes: broad therapeutic potential still under investigation
- ℹPickart et al. studies form the most extensive scientific basis on GHK-Cu
- ℹLimited oral bioavailability: topical and parenteral use are the most studied contexts

Frequently Asked Questions
What is GHK-Cu?▼
GHK-Cu is the complex of the tripeptide Glycyl-L-Histidyl-L-Lysine with copper ion (Cu²⁺). Naturally present in human plasma, described by Pickart (1973). Studies describe activity in collagen synthesis, VEGF and extracellular matrix remodeling.
