2 on 4 off cycle

Is there any reason why primo should not be used during weeks 3,4,and 5 of a 2 on 4 off cycle instead of morning orals, as laid out by Bill Roberts. I am also interested in hearing about any experiences with this cycle. I plan to start a series of 2 week cycles in a month or so. My drug selection is not definate yet, but will most likely consist of 75 mg tren/day along with 50-70mg oral winny/day. I have test prop and dbol on hand, but I think I’ll try the tren/winny first and see what kind of results I get.
