I've had good experience with Bulk, but I use the vegan blend (I find the vanilla to be the best one of the 4 or 5 flavours I've tried). I have also in the past bought unflavoured protein powder and calorie free flavour drops so that I can vary the flavour regularly.
what are the tastiest protein shakes ? I don't want to have to do extensive market research of boggin tasting protein shakes to work this out myself
