Whey Protein Isolate/ Concentrate is a Low-Temperature Ultra Filtered Australian whey protein which remains completely undenatured. We believe it is the purest Whey Protein Concentrate available on the market, with a higher level of protein and lower levels of fats and carbohydrates than any other product we have sampled. Our Whey Protein Concentrate (WPC) also has much lower levels of sodium than most available. It is naturally rich in amino acids, particularly the Branched Chain Amino Acids (BCAAs) and glutamine which ensures optimum muscle growth.
