The best thing to do is actually prime you body for a bulk. 6 to 8 weeks out from you cycle (bulk) start a carb cycle or even run a slight caloric defecit to lean out as much as possible and prime your body to better uptake all the calories and nutrient youll be supplying it when you start your bulk. Then the day you start your cycle start your bulk and watch yourself blow up, quickly.
This is a much better and more efficient transition as opposed to a bulking diet straight into another bulking diet. You body really only wants to do one thing for so long before it doesnt work as good as it once did. Like guys that bulk for years on end, makes no sense.
