I'm new here. First of all sorry for English, I am studying it so..ok, to the point

I am running out of maximuxcle prograin extreme (2kg) I only used it the days when I worked out before going to bed. So 2-3 times per week, 400ml of water with 120ml of the powder. Somedays I drunk it after working out in the gym because I thought it was the best moment.
But now, I have just read the label of the new powder I bought: nutrisport 90+ protein and it says that it's recommended to drink 2 scoops before going to sleep, and another serve (2 scoops) in the morning, just when wake up.
I read here that the only moment right to drink protein powder is after working out, I was agree, but it is just the contrary that the label says, and they are the guys who is suppose that know about this stuff as the created that formula specifically.
So, what do you think? I have no clue what to do when I start this new powder. I am confused :S
Thanks and congratulations for this website.
