FAQ
Is unflavoured protein cheaper?
Often, per kg of protein, because there is no cocoa, flavour or sweetener taking up weight, so protein per 100 g is a few points higher.
What does unflavoured whey taste like?
Mildly milky. Most people mix it into smoothies, oats, yoghurt or baking rather than water.
