Topical application and microneedling enhance delivery research like the 2025 Kuceki study shows that combining GHK-Cu with microneedling (which creates micro-channels in the scalp) dramatically improves delivery to the target cells and produces measurable regrowth
(2003) suggested that the cleft may enable large peptide substrates to access the active site, whereas the narrower tunnel formed by the -propeller could serve as a conduit for exit of dipeptide cleavage products
Research also notes that natural levels show a GHK-Cu decline with age, with levels falling by about 60% by age 60, a pattern linked to reduced healing, skin health, and regenerative capacity in the human body
