I just stumbled upon AussieNutrition.com.au, they have WPI alot cheaper than Protein Direct, 10Kg for $190 at Aus nutri, or $260 at Protein Direct. Their protein, EAA and Non-EAA levels are pretty much even. Thats the WPI though.
The price difference for WPC $150 at Aus nutri or $180 at Protein Direct. Protein, EAA and Non-EAA levels are better as well in the cheaper Aus Nutri stuff. What I dont get is at the top of their site it says 'Our products are imported from the best manurfacturers in NZ' then under the product information it states 'Product Of Australia - Packed in Australia under the following strict standards: DFSV and AQIS (Approved exporter)'
The Protein Direct stuff comes from USA.
