GN 100% Whey Protein is a premium whey protein blend, delivering over 19g of protein per 25g serving, from both 80% whey protein concentrate & 90% whey protein isolate. Unlike most whey blends which will use only a 'sprinkle' of isolate, GN™ 100% Whey Protein has an 80:20 split of whey protein concentrate & whey protein isolate. This produces an outstanding amino acid profile that is particularly rich in essential branched chain amino acids (BCAAs) & glutamic acid, making it the ideal choice to fuel recovery & lean muscle gains.
