I think you should keep it around the same tbh mate some guys take tons extra when on gear dome dont and are fine try and keep it the same if your bulking ud eat more foods so ud get extra proteins in from your good carbs extra milk cheese and so on lots of guys dont count that as part of their protein i do works grand for me gear or not so keep it the same lol but bulking ud get more in anyway natty or not cutting keep it as high as you can mate dont want to be just wasteing money on food your body isnt going to be getting much from. 1.5gs per pound of bodyweight is good even a bit less or a bit more wont harm your gains to much.
