The most commonly mentioned effects include mild nausea in some users (typically transient), injection site reactions (redness, minor discomfort), mild headache or dizziness (uncommon), and sleep disruption with late-day dosing (reported by some users)
The same reaction can occur on protein cysteine, and the formed GSNO group functions as important intermediate in NO metabolism, a critical player in fulfilling the biolgogical function of NO in signal transduction ( S -glutathionylation (Zeng et al., 2001) or thanks to catalytic activity of GGT generate S-nitrosocysteinylglycine that in turn can be cleaved by a membrane dipeptidase thus forming S -nitrosocysteine (S-NO)

L-Glutathione is commonly used for: Oxidative stress and cellular protection: Helps neutralise harmful free radicals and reactive oxygen species, protecting cells and tissues from damage caused by ageing, chronic diseases, and environmental toxins
These modifications can alter protein conformation or impede protease access, thereby preventing further truncationas observed for Tau and other proteins 85,86
