When it comes to protein im fairly fussy having tried most of the top brands over the years.
ANS N-PRO stacks well above the rest in terms of flavour, mixability and nutritional contents.
The Chocolate flavour is by far my favourite its a smooth creamy texture and not too strong or sickly which is important if your having up to 3 shakes a day!!
One of the other major factors I consider when considering purchasing whey protein is how easily its cleaned out of your shaker when you are done! I know a lot of other people can feel me on this one, ANS is easily washed out which is a bonus!
You cant go past N-Pro if your after a high quality great tasting protein powder - I even used this right up until the day before my last bodybuilding competition :)
