I was under the impression that it was not needed with this? Does it just depend on the dose?

I also was wondering... if I took 20 mg's of this daily simply for cutting.. how would it do?

My current stats are 12-14% bf at roughly 1700 calories a day. I do cardio 6 days a week also. Just want to cut that extra 4-6% bf off. I'm ok if it takes 8 weeks or so. I want to go easy on my liver.
