I usually half the dose on off days and spread out. So if taking 30 mg on lift days I'll take 15 or 20 mg on off days but take 5 mg every 3 hours. Lower dose is less harsh on liver.
I maintain the same dose on off days the only time I decrease is when I start to taper. Everyone is different, experiment try it one way this cycle and another way next time keep notes see how your body responds
