The mechanism likely involves both the opiate receptor effects and DSIP's normalization of stress hormones, which become dysregulated during addiction and withdrawal
That said: human data remains limited, sample sizes are small, and no studies have directly compared direct glutathione supplementation against precursor approaches on meaningful clinical endpoints
Human plasma contains the tiny tripeptide GHK-Cu, which occurs naturally
However, considering GHKs high affinity for copper (see below) and essentiality of copper for cell growth, it is virtually impossible to have copper-free GHK in a living system
The disulfide bond between Pt GSTF8 residue C13 and GSH was reduced on-column with 20 column volumes of rPPS buffer (20 mM potassium phosphate, 200 mM NaCl, 10 mM DTT, pH 7.4), at a flow rate of 5 ml min 1 and the column was then washed with 40 column volumes of PPS buffer at a flow rate of 5 ml min 1 to remove free GSH
