Antioxidant and DNA Repair Support GHK-Cu has been shown to: Reduce oxidative damage Stimulate antioxidant enzymes Support DNA repair pathways Evidence-Based GHK-Cu Peptide Benefits for Skin Health Research supports several aesthetic and dermatological benefits, including improved firmness, reduced fine lines, and enhanced wound healing
It's also worth spacing this away from any separate iron supplements
Furthermore, the effects of oxidative stress on neurogenesis and neuroplasticity cannot be overlooked
This makes copper peptides particularly valuable for individuals who cannot tolerate stronger actives or who have sensitive skin
The "right" dose sits in a narrow window that depends on: Delivery method - injectable GHK-Cu vs topical GHK-Cu vs oral/sublingual GHK-Cu Goal - skin rejuvenation , hair and scalp support, wound healing , general anti-ageing Individual factors - age , skin type , baseline GHK levels , other peptides being stacked Natural plasma GHK falls from roughly 200 ng/ml at age 20 to around 80 ng/ml by age 60
