So the study was done in 1991 and it was published at the PubMed where they were injecting two grams of IV push of glutathione and what they found out was 100% of the glutathione stayed in the plasma and nothing ever entered the blood cells

Alternatively, liposomal glutathione, or IV glutathione are more effective to raise glutathione levels within the body
Upon phosphorylation by RIPK3, MLKL undergoes oligomerization and translocates to the plasma membrane, where it induces pore formation
