GSH supplements would seem to be the most efficient way to increase cellular levels of GSH because if significant amounts of GSH are absorbed intact and are biologically active and also if the digestion process breaks down additional amounts of the supplemental GSH into its precursorswhich would then be also absorbed and available for recombination into GSHthe inter- and intracellular GSH transport mechanisms would be shifted in favor of increased cellular GSH

BPC 157 and its potential role in tissue regeneration: current perspectives

its strictly about understanding the mechanism within a controlled research setting

Intramuscular The intramuscular route avoids the problems associated with oral administration and the bioavailable fraction approaches 1

These authors also emphasized that the FCS-based techniques, such as fluorescence auto-correlation spectroscopy (FACS) and fluorescence cross-correlation spectroscopy (FCCS), being combined, can be used in quantitative analysis of molar concentration, diffusion coefficient and hydrodynamic radius, homo- or hetero-interaction, dissociation constant, and fluorescence brightness (Wang et al., 2022)
