Switching orals?

I've had this on my mind and I've seen it done in a few cycles. Say I take 30mg Dbol for 4 weeks followed by 2 weeks of Drol, is that more or less harmful to your liver than doing 6 weeks strait of Dbol? ie: are all orals liver toxic in the same way or by changing them up can you reduce the over all damage and maybe run them longer.

Drol is more toxic than dbol because of the higher milligram doses required to reap benefits.

50mgs ed -vs- 100mgs ed

if your on your still a newbie to cycling stay off the drol. save your liver for when your really gonna need it.
