I'm not sure I get what you mean?
By "no bullshit mixed in" I mean that there is no artificial crap in the shake and that you can be sure there is 30 grams of protein in a scoop as opposed to some flavoured shake saying on the label that it contains 20g of protein in a 30g scoop when in fact it may only have 10g. It's very easy to disguise the true nutritional value of a product when there are a lot of ingredients mixed in.
I always drink my shake with some carbs (milk or small snack). Consuming pure protein without carbs is almost worhless as far as recovery is concerned. Only bodybuilders in a cutting phase should consume protien on its own IMO.
