I am not arguing the point that it stimulates MPS, HOWEVER we are talking about the refractory response(you mentioned it)
If you feel that way then you are doing the exact opposite of what he is recommending.. You are taking his theory, and literally doing, what he is trying to have you avoid..lol
If you believe his theory, then what he is saying is by doing what you are suggesting, is when you create this refractory response.
You are taking that study above but not accounting for the actual refractory period.
What he is proposing is your day should look like:
Meal
bcaa
Meal
Bcaa
What you are suggesting is:
Meal
Meal(whey)
Meal
Meal(whey)
As you are not getting that sharp spike in plasma AA's with whey.

PS. I am not disputing whey at all, just in the fashion you are using it to avoid the refractory.
