Always wondered about this to get the most out of your cycle with lean gains..

Say you were doing 250 mg Test E bi-weekly (500 mg for the week)..

How would you go about increasing calories? Would you still do ~500 over maintenance, or would you increase protein/carbs drastically to say 1500+ over maintenance? Which produces the best results for lean gains?

Also, what's the best macro split? 20/40/40?
