The idea behind shake is, it is not a meal but a replacement, where possible get you protein from Food rather than a shake.
As soon as You wake is a Must and same just before you head to bed.
The rest of Day the likes of Chicken is much better but if u cant do that yea take a shake.
I myself have a shake on waking and have Breakfast 1 hour later, the next shake i have is at 6.30pm just before i workout and i have a shake straight after workout too.
Within an hour of having my post workout (after training) shake i have a meal too.
With the true whey 2 Scoop is 19g, so if you want almost 40g of protein take 2 scoops.
