Customer feedback reports easy mixing and good value, but opinions on flavour differ and some customers describe the texture as grainy or chalky. The reported duration is also mixed, with some saying it lasts about five weeks. These experiences matter for a large tub with 133 listed servings, since flavour and texture could affect whether it fits your routine. Aggregate ratings are mixed overall, so they do not establish a single consistent experience.
