Whey protein hydrosolate tastes crappy, is way too expensive, and is heavily denatured. The "studies" mentioned were done on rats and patients with cancer and crohn's disease. To my knowledge there are no studies demonstrating any of this in healthy athletes or weight trainers.

What is not mentioned is that starvation affects how well the body will store incoming protein, leading to falsely elevated BV measures.

There is supposedly an "enzymatic" process that doesn't denature the protein as much and is more cost effective then the older methods but none of the other assertions have any real grounding. When compared to isolates in general we are talking about percentage differences that would likely be completely negligible in healthy persons, especially if that person weren't "starved" to begin with.
People are nitpicking this stuff way too much. If your are chronically undereating and are not taking in enough protein then these small differences, if they exist" might make a difference to you. But someone on a "bodybuilding diet" SHOULD have a positive nitrogen balance to begin with. If anyone thinks that spending a huge amount of money on the whey supplement they use for post workout will make or break them, then they need to seriously re-examine their dietary practices. And isolate may be better than a concentrate or traditional mix, especially in terms of comfort but to state that hydrosolates are superior just has no proof that I have seen.
Finafreak I agree. Your pwo is fine. Use plenty of water and you may want to use a 50/50 malt/dextrose mix. OR use a way maize product.
