GHK-Cu: The Copper Tripeptide and Its Role in Regenerative Science
GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper complex and a focal point of modern regenerative research. Originally isolated from human plasma, this tripeptide is a native signaling molecule whose concentration naturally declines with age. In the Canadian research community it is studied for its ability to modulate cellular pathways and gene expression — not as a therapeutic drug.
Molecular mechanism: gene “resetting”
Gene-profiling research suggests GHK-Cu can up- or down-regulate thousands of genes, promoting a more youthful expression profile in older cells.
- Extracellular matrix (ECM) remodeling: stimulates synthesis of collagen and glycosaminoglycans while modulating the metalloproteinases that break them down.
- The copper factor: delivers copper into cells to activate pathways such as lysyl oxidase, essential for cross-linking collagen and elastin.
- Wound healing & angiogenesis: promotes formation of new blood vessels for tissue repair.
Key research domains
- Dermatology & skin aging: studied for skin density, firmness, and elasticity via dermal fibroblast activity.
- Hair-follicle biology: investigated for follicle size and micro-circulation.
- Systemic regeneration: preclinical models explore lung, bone, and connective-tissue repair and oxidative-stress mitigation.
Regulatory & safety context in Canada
- Not approved by Health Canada for human use; no DIN or NPN.
- Sold strictly for in-vitro/laboratory research only.
- Source only high-purity (HPLC/MS-tested) material from reputable suppliers — every Nuvion lot ships with a certificate of analysis.
Laboratory handling & storage
- Light sensitivity: copper peptides are light-sensitive — store in amber vials / dark conditions.
- Temperature: store lyophilized powder at −20°C long-term; once reconstituted in bacteriostatic water, refrigerate at 2–8°C and use promptly.
