I dont know about d,bol, cant get it where I am, But I do know when I do a course I must increase my calories or risk very minimal gains. Depending on how many calories your eating now is depentand on how much you will need to increase.
I'm 114 kg and off cycle I consume around 4000-5000 calories. On cycle I try to increase this by about 1500 calories. Arouind 400-500g of protein and 200-350g carbs.
Depending on your weight is the answer to how much you will require. This info is easily found on the web, so do a search.
Some people debate on whether extra training is an advantage or not, for me I repair much quicker, up the intensity and the length of my sessions, and dont even take a day off, It works for me, and believe so for much of the population.
As I said we cant d,bol where I am, so someone else will have to help you with the best manafacturer.
Good luck, and dont forget the 3 main rules- Eat well, sleep well and train f#cken hard.
