glutathione is a thiole in the reduced and the oxidized forms. The thiol group Molecular structures of LMW thiols:
Description
GHK-Cu promotes collagen synthesis in skin cells naturally and effectively

Improved Energy Levels By aiding processes that increase cellular energy production, glutathione can help improve endurance and vitality

Moreover, the data from multiscale molecular dynamics simulations suggest that suppression of phase separation is associated with the loss of proteinprotein interactions in the TDP-43 CTD and enhanced solvation of negatively charged groups 90

Those compounds modulate neurotransmitter levels for immediate performance effects
