NHS guidance describes an initial phase that can be every other day for 2 weeks (or until symptoms improve).Maintenance schedules are often every 23 months in appropriate long-term cases
GHK-Cu stimulates the production of dermatan sulfate and glycosaminoglycans that hydrate and plump the dermal matrix, measurably improving skin thickness and density over treatment courses

GHK-Cu: The Copper Peptide That Rewires Gene Expression for Tissue Repair GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring tripeptide first isolated in 1973 by biochemist Loren Pickart, who observed that plasma from younger individuals stimulated regenerative processes more effectively than plasma from older adults.21 Tracing this activity to a small copper-binding peptide, Pickart launched over five decades of research into a molecule with an unusually broad biological profile: it stimulates blood vessel and nerve outgrowth, increases collagen, elastin, and glycosaminoglycan synthesis, and supports dermal fibroblast function.22 The Gene-Expression Story What distinguishes GHK-Cu is the scale of its gene-regulatory effects
