Prescription topical GHK-Cu does not require cycling off, because the collagen-stimulating effects reward uninterrupted daily use

Copper is essential for the activity of enzymes involved in collagen cross-linking (lysyl oxidase), antioxidant defence (superoxide dismutase), and angiogenesis

Given that cellular function depends critically on precise copper homeostasis, any disturbance in this balance can have severe pathological consequences [11]

However, intensity should be balanced against the limited long-term safety data
