What is the success rate of GHK-Cu for wound healing?

Clinical studies report 60-80% improvement rates in wound healing parameters (closure time, collagen density, scar quality) with GHK-Cu treatment compared to controls. Success varies based on wound type, patient health status, and treatment protocol. Chronic wounds and diabetic ulcers show particularly notable improvements. <a href='https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4594048/' target='_blank'>GHK-Cu clinical success rates</a>
