Liver Detox

A buddy of mine finished a cycle just about two months ago and took some D-bol, but he didn't take any detox. He will be on another cycle in a while and will be taking some Anadrol 75's, I'm going to get him to take some detox for his next cycle. My question is, would it benefit him to take any liver detox now, even though he finished his cycle a while ago. And my second ? is what liver detox should he take and what amount for his next cycle, also the cheapest place to get it, only place I know of is the A-F store.
thanks for your help bro's
