Here are already some on Glucofast poorly written. So bad that I had not bought it almost. But my experience is a little different. Taste - almost no taste - slightly sweet Smell - has a slight odor after no idea - not unpleasant, not a "stink" Solubility - powder in a container - top and stir water - ready! Of course, it does not dissolve as well in like a spoonful of sugar in coffee :-) but who has stirred a little lumps. Who wants it even faster as I machts 3 seconds using the hand blender and you're done. Compatibility - no problem even for larger quantities. Price - sorry but whom EUR 17 for more than 3 kg is too much want but please "Lurdwasser" drink and hope for a miracle - that costs at least nothing.
