Its one of the most extensively studied molecules in skin science, largely because of a fairly simple observation: GHK-Cu levels fall as we age, and a lot of what it appears to do in the lab lines up neatly with the changes we associate with ageing skin

Key structural characteristics include: Peptide length: 15 amino acids (pentadecapeptide) in linear configuration Molecular formula: C62H98N16O22 Molecular weight: Approximately 1.42 kDa Structural type: Stable synthetic peptide fragment with proline-rich regions Functional domains: Contains multiple proline residues contributing to structural stability Sequence modifications: Lacks methionine residues, enhancing oxidative stability Secondary structure: Predominantly random coil with beta-turn regions Formulation: Synthetic peptide dissolved in research-grade solvent system for spray delivery The peptide exhibits remarkable stability compared to many bioactive peptides, remaining active in gastric acid conditions and showing resistance to enzymatic degradation, making it suitable for diverse experimental applications
Found naturally in the human body's tissues and fluids, GHK serves as a signaling peptide that plays a role in tissue repair and regeneration
