Dorian Yates ShadoWhey, Chocolate

First batch (choc) I received was amazing. Second batch (vanilla) was amazing. Great taste and the powder was as fine as sand (due to anti-caking agent) so therefore mixed well.However, the third batch (choc) I received was different because the powder was clustered (absence of anti-caking agent) and mixed poorly and tasted bland. Reminded me of a typical Holland and Barrett brand. It is shame that DY has changed the recipe.
