robski, they seem expensive.

try www.cybercheckout.com

the cheapest, best tasting, highest protein content whey protein shakes ive found are by nutri-sport (they are stocked in a local nutricion store), and i can get 5kg for £45. 2 scoops per shake, contains 45g of protein per shake.

bearing in mind the site u mention above is selling whey protein for £29.99 for 1kg, i challenge you to show me (apart from taste) that the £45 for 5kg stuff isnt as good.
