Protien, Big Bucks? Or Big bags?

Is there a real difference in quality of protien? I have been using isopure 100% ion exchange whey protien, is that different from the cheap stuff? Work the extra cash?!? Besides that is has 50grams per serving, is there a quantifyable difference?

One very simple way to evaluate the quality of the whey product you buy is to determine an efficiency ratio. If you'll divide the grams of protein in a single serving by the size (again, in grams) of that serving, you'll get a decimal number that tells you how much of your serving is actual protein.

For example, if your "serving size" is 50 grams, but it only contains 42 grams of protein (8 grams of 'something else'), then you'll have an 84% efficiency ratio.

50 / 42 = 0.84 ~> 84%

Next, to figure cost effectiveness of your whey, calculate the cost per gram of protein. If, according to the nutrition label on the whey container, there are 30 servings (of 42g of protein in each) and the cost for the container is

$48.89 product price
$03.67 sales tax
$07.50 shipping
$60.06 total

... then your cost per gram of protein is $60.06 / (30 x 42) = 4.77¢ per gram.

The same logic can, of course, be applied to the cost effectiveness of any food (with respect to the nutrition that it offers your body).

I've noticed the cheaper protein doesn't agree with my stomach as well, i like the better stuff, (i use musclemilk) cause it doesn't give me the protein dumps. hahah

The main thing with ISOpure is that it is almost completely lactose free and some are zero carbs. If you aren't lactose intolerant and can stand the small amount of carbs that are in most proteins, I'd switch.

I played football in college, you might wanna try something like Optimums Nutritions 100% Hydrolized Whey.  It's a mid priced protein supplement that is packed with BCA's and tons of Amino Acids, It's generally pretty inexpensive.  It's sold at your local GNC store.

Is there any real difference between Miller Lite and a high quality German beer?
 
There's LOTS of differences between various protein blends and companies.
 
Ranging from employees, adhereance to standards, quality of the facility's processing, source of the protein purchased, clean room standards, quality accurance checks, etc.
