Macronutrients. The amount of protein/carbs/fats/cals you consume per day.

In order to make gains and maintain the size you receive from the cycle, you'll need to eat over a certain limit to compensate with the new mass you have put on.

This is why you aren't cycle ready yet. You need to address your diet first and your weight to height ratio shows me that the cycle will only lead to disappointment at the rate you are eating.
