The effect builds with titration, and many patients notice meaningful appetite reduction within the first two weeks

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

BPC-157 is a synthetic peptide that is derived from a natural protein known as Body Protection Compound
They're most effective when taken consistently rather than just when pain peaks
