Does protein powder really work ?

Got the little egg pancakes off to a T. The mix is 6 whites and 1 yolks. This muscle building business takes up a lot of time i need it to be more convenient, 160 grams of protein is a lot of eggs ( about 40 per day). You can see the convenience of protien powder ( 5 shakes per day on average to make 160 grams).. but does protein powder actually work ?

Here's one I cooked earlier. It tastes better than it looks.

just a quick calculation: 40 eggs in the Uk costs about £ 3.33 so thats about £ 23.33 per week.

I have seen on ebay 5kg of protein powder for about £ 40.00, This equates to 40grams of protein per 50 gram serving, this gives you 100 servings or last about 25 days based on 106 grams per day. not bad ................if it works!
