Guys, its excessively simple
You need about 1.8 to 2.2grams for optimal muscle growth, which happens in the recovery phase AFTER a workout. If you didnt work out, the protein wont be used at all.
I weight 125kg. Thats quite alot of protein. I try to be at 320grams/day to make sure i'm over the optimal. Because its difficult eating enough quality protein source, i take shakes. Protein shakes just help to increase your daily protein count to the desired level in an easy way.
However. You need all sorts of stuff. Vitamins. Minerals. Biomolecules. Dont take supplements, eat properly. Eat your
white and red meat. Eat good carb sources. Eat diary products. Eats vegetables based on your needs.
People think they'll get buff as fuck because they took a scoop of fuckign creatine. Or 'feel' the protein shake.
No, you need to 'feel' the muscles you trained. And know that you only give them all that stuff and protein, to aid recovery.
