Hi Scott,
Not sure if you are aware, however approx 6 months ago, fonterra WPI stock ran dry....they slowed or even stopped production of WPI due to non producing cows. This affected many protein businesses throughout the world....Luckily we where able to find a new supplier rather quickly who had access to many different brands.
We spent the following month trying all the different available brands and came upon the one we are using now. We selected this for many reasons....mixability was far superior to fonterra, Nutritional values and amino acid make up ....again far superior, taste....again.....much better.
In all, we found a product which beats Fonterra hands down, and we will continue with this product even after Fonterra makes a come back....If they ever do, as im told they wont be beck for the rest of this year now also.
