Consider Timing: Try taking your glutathione at different times
Owing to its high concentration in the cell (~10 3 M) 1 , the GSH/GSSG pair acts as the main intracellular redox buffer, plays a key role in the detoxification of reactive oxygen species (ROS), and participates in redox signalling 2
The major electrolytes:sodium, potassium, and chloride [online]
The copper content of GHK-Cu formulations has been a theoretical safety consideration, given that excessive copper can be toxic - however, the amounts used in cosmetic and research applications are extremely small, the copper is tightly chelated by the peptide (reducing free copper availability), and topical absorption of copper from these products appears minimal and well below levels that would cause systemic copper accumulation or toxicity
