GHK-Cu 5mg Testing (Body Protection Compound 157) is a synthetic pentadecapeptide derived from a protein found in gastric juice
Irritability and anxiety Some community reports describe irritability, restlessness, or heightened anxiety, occasionally framed as overstimulation

GHK-Cu operates through multiple mechanisms: Gene expression modulation : Regulates over 4,000 human genes, including upregulation of collagen, elastin, and decorin synthesis, and downregulation of inflammatory and tissue-destructive genes Copper delivery : The copper ion is essential for lysyl oxidase (collagen cross-linking), superoxide dismutase (antioxidant defense), and cytochrome c oxidase (cellular energy) Growth factor stimulation : Increases production of FGF, VEGF, and other growth factors involved in tissue repair Glycosaminoglycan synthesis : Stimulates production of proteoglycans and glycosaminoglycans for skin hydration and structure Anti-inflammatory activity : Suppresses inflammatory cytokines including IL-6 and TNF-alpha Matrixyl# Matrixyl (pal-KTTKS, palmitoyl pentapeptide-4) is a synthetic peptide consisting of five amino acids (Lys-Thr-Thr-Lys-Ser) conjugated to a palmitic acid chain

Uncontrolled VEGF-A elevation has been associated with pathological angiogenesis, including tumor vascularization
