Injectable GHK-Cu, however, works systemically , meaning it can support healing and regeneration throughout the body, including: Skin and connective tissue Tendons and ligaments Post-procedure recovery Hair follicles Areas of chronic inflammation By bypassing the skin barrier, injections allow GHK-Cu to interact directly with cells involved in repair and regeneration
