If a whey powder is 80% protein by weight. What makes up the last 20% except for the few carbs, from sweetener and flavour?
vanilla powder, seriously, they do to cocaine what they do to whey too. they mix it up to get more. pure whey can only be found in the mountains of austria near berchtesgaden.
theres a hell of alot more than 1 gram of fat in that 'gold standard'.
