This question was asked already and they said they couldn't disclose the information..
However I did some math to try and figure it out..
Difference in Cal/Fat between the unflavored and flavored(vanilla) were 1.27/.07
Cal/Fat of unflavored concentrate of 111.65/1.83 at 60% yields 66.99/1.098
Cal/Fat of unflavored isolate of 104.72/.3 at 40% yields 41.888/.12
Add the two together and get 108.878/1.218
Add the difference from flavoring and get 110.48/1.288
Blend was rated at 109.29/1.26
comparing the results with what the blend is rated at tells you that a rough estimate would be 60% concentrate and 40% isolate..
PS sorry All The Whey if I'm actually right =P you can delete this if you want
this is what boredom does..
