Does peptide GHK - Cu have any antioxidant properties?

First off, let's talk a bit about what peptide GHK - Cu is. It's a naturally occurring copper - binding peptide that's found in human plasma, saliva, and urine. Its concentration in the body decreases with age, which has led to a lot of interest in its potential health and anti - aging benefits.

The Basics of Antioxidants

Before we dive into whether GHK - Cu has antioxidant properties, let's quickly go over what antioxidants are. Antioxidants are substances that can prevent or slow damage to cells caused by free radicals. Free radicals are unstable molecules that the body produces as a by - product of normal metabolism, but they can also be generated by external factors like pollution, UV radiation, and smoking. When there are too many free radicals in the body, they can cause oxidative stress, which is linked to a whole bunch of health problems, including aging, cancer, and heart disease.
