Meal Replacement: Isolate vs. Milk protein

[tallguy23]

I work as a teacher and I absolutley can not eat a solid meal during the morning hours. I have 2 minutes between classes and that's it. I have been marking a MRP for the past year with 2 scoops of isolate, anywhere from 1/2 to 1 1/2 cup of ground oats, and 1 to 1 1/2 tsp of olive oil depending on if I am bulking or cutting. I eat my regular lunch about 2 hours and 5 minutes later. I can take 20% off this week when I order from allthewhey.com and I noticed they have milk protein. Is it worth using this in my shake or can I just use isolate? I know the fiber and oil slow down digestion, do the slow it enough or should I just buy the milk?

it's obviusoly good to consume different types of protien but the main thing here to make sure you get the protien. for mrp type shakes i think you should mix the protiens between isolate, milk, and casien so that you get a more constant flow from ingestion till the next meal.
in short, if you must do mrp's then mix the protiens for better results.
