You dont get strong instantly from consumning protein
powder.
Protein powder is just protein in liquid form.Just think of it as a
pureed chicken breast or something.
It is just used to fill up the kcals/calories needed and if its too
inconvenient to go buy food sometimes.You can make a shake and go
out and eat later.
I dont know why people keep thinking you get strong from drinking
some powder NOT the way you workout and other factors.
Its like saying you can get strong by eating cans of spinach but
laze around the whole day.
