Niacinamide with Glutathione

Antioxidant enzymes, such as superoxide dismutases, catalase, and glutathione peroxidases (GPx) are essential for maintaining the delicate balance between ROS production and scavenging, thus protecting cells from the harmful effects of oxidative stress [18]

Either the GHK-CU isn't suitable for your biochemistry, your protocol needs adjustment, or an external factor is interfering

The concentrations of reduced (GSH) and oxidized (GSSG) forms of glutathione were measured using an HPLC system (Thermo Fisher Ultimate 3000) equipped with a YMC-Pack ODS-A column (5 m, 120 , 4.6 150 mm
