The copper content of GHK-Cu formulations has been a theoretical safety consideration, given that excessive copper can be toxic - however, the amounts used in cosmetic and research applications are extremely small, the copper is tightly chelated by the peptide (reducing free copper availability), and topical absorption of copper from these products appears minimal and well below levels that would cause systemic copper accumulation or toxicity

This attrition is what scientists call the Hayflick limit, named after Leonard Hayflick, who discovered that normal human cells divide roughly 4060 times before stopping [23]
