Free Cu2+ is toxic (Fenton reactions, hydroxyl radicals), but the GHK-Cu complex is stable, diffusible and delivers copper in a targeted manner to copper-dependent metalloenzymes: lysyl oxidase (collagen/elastin crosslinking), Cu/Zn superoxide dismutase (SOD1, antioxidant defence), tyrosinase (controlled melanogenesis), dopamine-beta-hydroxylase
This is particularly relevant for muscle strains, tears, and the general microtrauma that accumulates from high-volume training
A balance between free radicals and antioxidants is necessary for proper physiological function.
barbarum exhibited antioxidative and anti-inflammatory effects, primarily through the modulation of mRNA expression levels, suggesting its potential to positively impact metabolic disorders
