Another thing to note as I don't think anyone else has said, drink water, a lot of water. You want to be downing about 2.5l a day from my experience if your not already, it helps a lot. And if you want some decent low price protein have a look on myprotein.co.uk. Thats where I ended up after spending a fortune on all the different brands and found you save quite a bit of cash, plus the ground porridge oats and stuff they sell is good to throw in your shakes to add a bit more carbs and aid the bulk!
