IsoMorph 28 Pure Whey Isolate is the end-all, be-all AAA-rated whey protein isolate product. In fact, its not just a whey protein isolate-it is 4 ultra-pure whey protein isolate, including hydrolyzed whey protein isolate. APS manufactures IsoMorph 28 pure whey isolate in our GMP facility. We guarantee this to be the purest and freshest whey protein isolate available anywhere. Over 90% of the companies that sell protein dont actually manufacture it; theyre just marketers. At APS Nutrition, we manufacture our protein in our own GMP facility, so we control all aspects of the manufacturing process from start to finish. IsoMorph 28 pure whey isolate contains extremely small protein molecules that are literally 18x smaller than the proteins from almost every other product on the market (1000 Daltons vs 18,000 Daltons). This means that they can be completely absorbed because the intestinal wall allows them to pass through thanks to their small size. Since these small proteins get into your bloodstream via the small intestine, they get to work right away and require minimal effort from your digestive system.
