glutathione

What do you guys think about injectable glutathione? I haven't found much info on it

Injection are becoming the best..IV's are the top, but time consuming and expensive. there is much debate about absorption with oral , thus
precursors like NAC must be taken also...All oral is very debatable.. INjections and IV seem the way to go...I have had good success with NAC but nothing
like the IV's I did..of Glut..
