It's just past midnight here in Hawaii and I just had some fried chicken (breast, drumstick and wing) and a 40 gram protein drink. Easily 70+ grams protein.
Chicken breast has lots of protein, i can't really see a problem with getting up to 300g protein ed over a longer period of time.
When i eat about 400, i can only do so for a few weeks until i get sick of eating... usually in the end of this bulking phases, i tend to down too many shakes just to get it over with....
right now, i eat LOTS of sashimi, mostly tuna and salmon. A good meal for bulking is buying a piece of sashimi quality red tuna, then cut that into quarters, not slices, throw in half an avocado also sliced, flavor with sesame oil and soy sauce. tastes amazing.
