Hi, I think that this is the best whey protein powder. I don't know about prices in UK but in my country the price of 1 gr protein is cheaper than buy milk or meat. I mix protein powder with whole milk and you can mix 400 ml milk with half a dose of protein powder. Thus you will use the box for 2 or 3 months and it will not be so expensive. And yes, you won't bulk The tastes of protein powder are so delicious that many people substitute candy cravings with healthy protein shakes.
