funny thing is that you think its hard to eat 500g protien a day,,your body doesnt know wether you give it liquid or solid meals,,it dont care either,,liquid meals you will have to eat every 2 hours and solid meal every 3-4 hours,,if you sit on your ass all day long doing nothing you can eat both type of meals every 3 hours sometimes even 4,,
10 little carton of egg whites papetty usa foods = 500 gram protien,,in usa it is about 2-3 dollars per one little carton and that means you need to spend 25$ a day inorder to get your 500 gram protien and at the same time you can be vegeterian and eat no meat! if you dont like taste of pesturized egg whites you just add into it crystal light poweder pink lemonde taste or cranberry caffeine taste thing that has caffeine in it and zero sugar,,that make those eggwhites taste like heaven,,mixed with spoon and its real food not protien poweder which is also ok if you want to add it sometimes
you just got here over 500gram of protien a day for 25$ with out eating even one single meal of meat or fish
saying all that,,you still dont need more than 1.75 gram protien per pound for growth to happen,,sometimes even less,,2 gram per lb should be plenty and you beter be on hormones while takin 2 gram per lb
