It is produced during normal glutathione-dependent peroxide reduction and can be converted back to GSH by glutathione reductase
Although our experience suggests that hydroxocobalamin does not cause clinically significant interference with non-invasive pulse oximetry, there is evidence to suggest that co-oximetric blood gas analysis with several unique analyzers may be altered in the presence of hydroxocobalamin, specifically with false elevations of carboxyhemoglobin and methemoglobin concentrations and underestimation of true oxygen saturation values.5 There is no available evidence regarding the accuracy of other commonly utilized oximetric monitoring modalities (e.g., cerebral oximetry) following hydroxocobalamin administration

GHK-Cu, the tripeptide glycyl-L-histidyl-L-lysine bound to copper, demonstrates activity at concentrations that would seem impossibly small to anyone familiar with standard peptide dosing
