When you're on a cycle, when do you usually up your calories?

Do you up your calories after your injection?

Or

Do you up your calories when you feel the effects of Test E?

At what point should I consume 4k calories? What week do you suggest?

How I was thinking of approaching this was eat 2.5k calories 1st week then gradually move it up by 400 cals a week until it hits 4k.

What are your suggestion?
