You should could try ... a thought is maybe you could apply it in the liver area since GSH is needed there....
Or you could just try to supplement with the co-factors (glycine, cysteine and glutamic acid ((double check that)) or try some protein powder, but IMO the free form complex is better (Anabol Naturals) with some added cysteine or NAC could work as well. Make sure you take the co-factors such as folic acid or better folinic acid w/ some b12 (methylcobalamin).
There are some other things that help the body regenerate GSH, such as antioxidants such as Vit C and I beleive tumeric will help as well.
I can get the liposomal at wholesale or close to it if you needed it.
