well the dbol only part isnt the big deal as you can take dbol only and see gains from it, the problem there is as fast as ya gain when ya stop an oral only cycle your gonna lose it fairly quick.....people do bdol only all the time and do ok with it, and inject would be better but hey go with what ya can
now onto his worst idea of the whole thing running anything with no PCT is a recipie for disaster, HE IS GONNA CRASH HARDCORE and then become all depressed as he deflates like a popped balloon....
again if he really wants to do this (dbol only) at least tell him to read up on PCT and get some of that, its readily available and cheap so there is no reason why he cant....
