whey isolat and whey isolate concentrate

It does'nt look like there's that much difference?

Whey protein quality is first determined by the protein percentage. the higher the protein percentage the better the powder. No powder is 100% protein, the closest thing to 100% is the Ultra 97. it is 97% protein. Nothing is higher than that in the world. every once in a while it comes in at 98% protein. thats truly remarkable.

When a whey protein is called a whey "isolate" when its protein percentage is 90% or higher. A whey protein is called a whey "concentrate" when its protein percentage is 80% or under. you cant have a whey concentrate isolate.
