I agree, expensive. they should offer sample packets or smaller sizes.
Not a fan of chocolate - still chalky unless disguise it - made bars with them and that hide the grittiness. YouTube has a bunch of recipes, but does need to have something to adhere to like oatmeal.
I bought the chocolate and it's chalky (as I remembered shakes are) but... stuck with it now and have to make the best of it. So, I tried a recipe I found online that used vanilla yogurt (used plain with vanilla extract), hazelnut coffee (didn't have but would like to try), chocolate protein, milk (I used plain almond), peanut butter, and ice cubes. Pretty good taste. Also check youtube for how to put into protein bars - that hides the chalky taste for sure, but need oatmeal or something to adhere to - honey and peanut butter, dry fruit, etc - really nice I have to say except for gluten factor.
I assume the calories are based on my weight plus intensity.
