How Its Being Used Youll find GHK-Cu in: Topical serums (often post-laser or with microneedling) Compounded injectables and transdermal creams (off-label) PRP and hair regrowth protocols Common use cases: Post-surgical healing Cosmetic skin rejuvenation Hair regrowth (stacked with PRP or exosomes) Scar treatment Wound support The Evidence: Topical use has shown skin improvements in small cosmetic trials Gene expression and lab studies support repair, inflammation reduction, and mitochondrial protection relevant to cognitive decline Systemic use (injections, high-dose protocols) lacks long-term safety and outcome data Results are highly individual and confounded by other interventions (PRP, microneedling, exosomes, etc.) Is It Safe
Thus, cystine limitation suppressed mTORC1 and activated the ISR, the two major amino acid sensing pathways in HepG2 cells
