It is relatively mild on the liver in doses under 40 MG ED. I disagree about the need for 50 MG ED. I would recommend 40 MG ED which is proven in clinical studies to be effective at increasing lean body mass, yet mild in its toxicity. Any higher dosage starts to become a burden for the liver.
In either case I would suggest Tylers Liver Detox (6 Caps Daily) along with ALA (1500 MGS Daily).
Duca: 20 MG ED is not a a waste of time - you will see reslts but more in a toning/leaning and vascularity form rather than a lot of mass.
