The thing with the supplementary aminos is that to my knowledge they all included in whey and milk protein anyway, so if you're taking regular protein supplements, then bunging in bcaa's glutaminte and leucine etc, you might just be wasting your time.
Like Dan says Casein based/ Milk proteins digest much more slowly than Whey and don't spike your insulin nearly as much so are better used in the day as snacks or at night before bed to prevent catabolism when sleeping.
Myprotein strawberry milk protein is pretty decent in water, but I don't rate the other flavours. The impact whey range, almost all the flavours are palatable.
