Is one whey isolate powder different from another?

Once they say cold filtered whey isolate is it all pretty much the same minus the packaging?

[Chaps]

Their is ion exchange whey isolate and cold filtered, the ion exchanged whey has more protein per serving it's like 28grams compared to 25g's of the cold filtered both are very high quality my personal preference is the ion exhange more bang for your buck imho.

It depends on the quality of the brand. How they do there filtering and if the makers are being 100% truthfull. Chinese whey "isolate" doesnt compare to canadian or US sourced whey. they are NOT created equal.
