Fast becoming regarded as the ultimate whey protein blend, new Mutant Whey is a unique 5-Stage Whey Protein that supports muscle growth by increasing nitrogen retention in cooperation with intense weight lifting activity. New Mutant Whey has been developed after 28 months of dedicated research. It is the world's first protein to use specially selected proteins, each with their own unique uptake rate. This 5-Stage Whey Protein allows each source its own unique delivery to your digestive system. Produced in Fit Food's federally inspected GMP (Good Manufacturing Practices) licensed facility. GMP protocol is utilized in food, pharmaceutical and medical device manufacturing. This guarantees you, the finest quality, and safety, in every batch of Mutant Whey. They also go beyond just GMP. Their federally inspected plant also performs extra safety tests (e. coli, salmonella, lysteria, and other harmful pathogens) that are not routinely tested for in protein products. And on top of even that, Fit Foods own an additional export license (which allows them to export directly to over 85 other countries) which requires them to perform even more testing. Fit Foods are the only facility that follows all these procedures and possesses all these licenses and permits. The Formula... Nitroserum: A Unique Membrane Filtered Whey Protein Concentrate/Phospholipid Complex could be called the new "Diamond Standard" of whey protein. It also contains natural phospholipids and higher amounts of colostral growth factors. Micro Filtered Whey Protein Concentrates: These have been the traditional "Gold Standard" in whey protein; fast absorbing, lactose reduced and retaining more immunoglobulin protein fractions than whey isolate.. Cold Processed Whey Protein Isolate: Faster Absorbing, Lowest Carb WPI. At 97% protein, this is the highest protein source of whey, with the 2nd highest immediate nitrogen retention, and practically lactose free. ActiNOS: Hydrolyzed Whey Protein Bio-Active Peptide Isolate; Patent Pending whey peptides that absorb fast and have been studied for their effects on NOS (nitric oxide synthase), which is the enzyme that increases nitric oxide levels. Hydrolyzed Whey Protein Isolate: Provides naturally occurring critical bioactive compounds including di, tri, and oligo peptides, beta-lactoglobulin, alpha-lactalbumin, serum albumin, and immunoglobulins; this is the new "platinum standard", even faster absorbing than normal whey isolate.
