different types of whey protein

[BigBoi1881]

Im about to make a purchase of whey protein but was wondering what the difference between the types are.

- whey protein isolate
- whey isolate w.concentrate
- whey protein concentrate

[Titleist]

Isolates- About 90-96% protein, less fat, less lactose.
Concentrates- About 70-80% protein, more fat and lactose than Isolates.

Isolates absorb very fast and are ideal for PWO(along with Hydrolized whey, but HW tastes like shit, mix the two).
