See the last box of your second big picture, which says English direction, and the meaning is very clear. The first line says, use at most 2 spoonfuls, which means at most 2 spoonfuls a day. You should send the spoon here. So drink at most two spoonfuls a day. I usually only drink two spoonfuls on the day of fitness, one before exercise and one after exercise. If you don't exercise, you can drink a spoonful, which is better to take with meals or at breakfast or dinner.
The specific use method is also written. Adding 1 spoon to 300ml (or 500ml) is unclear. In other words, a spoonful of 300ml or 500ml water must be warm water, which can't be wrong. All the hot water used in protein will destroy the composition of protein. Shake well with warm water.
