I can answer a little bit of this. Whey concentrate (WC) vs Whey isolate (WI). Both wheys take about 40 mins to absorb. WI is (IMO) for people who are lactose intolerant and supposed to be ~90% pure. WC is far cheaper an ~80% pure, but you can get far more whey by buying WC if you are not lactose intolertant.
Muscle Milk is yummy, but it tested at 30% protein by total volume and through trickery claims 32%, but it doesnt say that is plain english, lets look at the label shall we :
