Whey Protein Isolate

As a result of advanced microfiltration processing, whey isolate is without a doubt the purest, most potent form of whey protein available. Unlike whey concentrate, for example, it contains little to no fat, lactose or cholesterol. What it does contain, however, is a complete amino acid profile, along with other key growth factors such as alphalactalbumen and glycomacropeptides. Whey isolate is fast-acting, highly bioavailable and packed with pure, muscle-building power. For the highest quality whey isolates, look for Ultra-Microfiltered or Cross Flow Microfiltered (CFM) processing.

    VP2™ Whey Isolate with Aminogenby AST Sports Science VP2™ is a premium Hydrolyzed Whey Protein Isolate, using the advanced protein technologies, "Micro-Fraction-Isolation" (MFITM) and "Controlled Chymotrypsin-Trypsin Hydrolysis" (CCTHTM) designed to isolate specific and potent individual protein fractions. Once isolated, these potent protein fractions are then cleaved into precise peptide lengths for scientifically proven higher nitrogen retention. This entire process is performed under cool, non-acidic conditions to ensure protein integrity. VP2TM is a precision protein formulation formulated to yield an "amino-specific" nutrient profile designed to increase muscle nitrogen absorption and retention to support lean muscle growth and repair. Now with absorption enhancing AminogenTM, VP2TM is optimized for better protein absorption. AminogenTM research shows this increased absorption rate raises levels of free amino acids, Branched-Chain Amino Acid levels (BCAAs), Arginine, and Glutamine better than without the patented enzyme system along with better nitrogen retention. VP2TM is specifically formulated to deliver nutrients, amino acids, and protein to your muscles! VP2TM Whey Isolate is combined with AST Micronized Creatine to support:- fast twitch muscle fiber size - lean muscle- strength - body fat reduction - recovery

    Original NytroWhey by ProSource 100% Pure Ultra Premium Whey Isolate Advanced Ultra Micro-filtration Technology Yields a Pure and Complete Amino Acid Profile The First Protein to Introduce True Gourmet Quality Taste and Texture Includes Powerful Concentrations of Protein Fractions for Enhancing Bioavailability, Immune Response and Anabolism Category Leader for Over 15 Years Available in Both 2 lb and 4 lb Sizes NytroWhey’s 100% whey protein isolate has been a recipe for muscle recovery and growth since the day it first appeared, and it continues to deliver results today for legions of athletes looking for maximum purity and anabolic power. One of the very first whey isolates to emerge as a go-to choice among the bodybuilding community, NytroWhey continues to provide this singular premium protein choice to thousands of athletes across America. Advanced Processing for Ultimate Quality and Value      As you know, whey protein is a complete protein source, containing all nine of the essential amino acids, making it an absolute staple for bodybuilders, other athletes and anyone concerned with overall health. How it is processed makes all the difference, however. For example, whey isolate contains the highest biological value (BV) of any protein. NytroWhey’s superiority is the result of premium protein sourcing and truly advanced processing that ensures the highest BV possible. The isolate in NytroWhey is precision-manufactured using high-performance, Ultra Micro-filtration processing, a precise and complex synthesis that involves ceramic cold filtering that delivers the purest, most bioavailable protein available today. This state of the art technology also removes the lactose and other undesirables typically found in other forms of whey protein. This cold filter processing also preserves even the most fragile protein fractions (alphalactalbumin, lactoferrin, and glycomacropeptides) that are essential catalysts for enhancing bioavailability, and boosting growth and recovery.      Alphalactalbumin is the primary protein found in whey and is rich in amino acids needed for muscle growth. It also helps enhance the immune system and has exhibited mood-enhancing support as well. Glycomacropeptides are high in branched chain amino acids and have been scientifically documented to induce muscle growth, help with diet support and possibly help suppress appetite. Lactoferrin is found in high levels in colostrum (mother’s milk) and has been shown to help boost the immune system and intestinal tract, among other related benefits.      NytroWhey also contains very high amounts of BCAAs, glutamine peptides and other precision growth factors the body needs for maximum muscle synthesis. This ultra-high purity and powerful concentration of micro-fractions means superior bioavailability, greater nitrogen retention, greater protein synthesis, and maximum anabolism, as well as a light, clean, luscious texture and flavor. A Legendary Whey      In a supplement category where products typically have a lifespan of three or four years, NytroWhey has been helping a sizeable contingent of hardcore bodybuilders achieve their physique and performance goals for more than fifteen years. That’s a legacy ANY manufacturer would be proud to call its own. Try a delicious NytroWhey shake for yourself and experience protein power in its purest and most bioavailable form!   Click to read about An inside look at the ProSource headquarters: See What Sets Our Brand Apart Use as directed with a sensible nutrition and exercise program.

    IsoFast 50 by MHP ISOFAST 50 is scientifically formulated for elite bodybuilders and athletes engaged in intense training programs to help promote muscle building, inhibit catabolism and improve recovery for maximum results. ISOFAST 50 utilizes micronparticulated whey protein isolate with Biohydrolase, a new advanced Biohydrolysis Technology, for amazingly fast anabolic muscle building activation. ISOFAST 50 goes even further than the industry standard triple microfiltration by adding two additional steps and technologies to its processing - Micronparticulation and Biohydrolysis. These two advanced technologies allow ISOFAST 50 to function like a Hydrolyzed Whey Protein (WPH) inside the body. Hydrolyzed whey protein offers additional muscle building benefits, because the hydrolysis process breaks down the WPI into di- and tri-peptides for faster absorption. In the development of ISOFAST 50, MHP scientists achieved their goal in delivering the great taste of WPI with the benefits of WPH by utilizing these advanced Micronparticulation and Biohydrolysis Technologies. -50 GRAM Protein Infusion in Seconds!-Ultra-Fast Absorption with Biohydrolyzed WPI Technology-Highly Anabolic Muscle Building Action-Helps Reduce Catabolic Muscle Wasting-Enhanced with Micronized BCAAs
