amazing flavours but protein break up?

This protein tastes absolutely amazing. The texture is creamy and it mixes very well. I used the Pro6 before this one and I can see that Rule One has really worked hard on the taste and texture. However, with Pro6 I knew the protein breakup of the 6 different kinds of proteins which now Rule One does not tell us with Source7. So I am not sure if I am having a majority of Whey Concentrate with very very small amounts of Pea Protein, Whey Isolate and so on. I wish Rule One would consider changing this in the future.

Thanks!

My first time buying protein powder. Never looking at another brand again. This is it. They even sent me extra packets to try out different flavors/ types of powders they sell which was so so cool of them. Thanks R1!!! -May
