Strong exfoliating acids (glycolic acid at pH below 3.5, lactic acid at high percentage) also destabilize the GHK-Cu complex by protonating the histidine imidazole nitrogen that coordinates the copper ion

These are unstable molecules that can cause oxidative stress, a process that can damage cells and contribute to fatigue or a weakened immune response

Some practitioners suggest that glutathione injection during fasted states may enhance cellular uptake and utilization, as cells may be more receptive to antioxidant support when not processing dietary nutrients
