Anabolic / Anti-Catabolic Bio-Efficient ProteinSustained Release Muscle FeederExclusive Micro-Feed TechnologyFast, Medium & Slow Release Profile (Pre/Post Workout & Before Bed)High levels of the Critical 5 Amino Acids (Glutamine, Arginine & BCAAs)Amazing Taste, Creamy TextureNaturally & Artificially FlavoredDietary Supplement PROBOLIC-SR Sustained Release Muscle Feeding Protein PROBOLIC-SR's unique protein blend, exclusive sustained release micro-feed technology and high concentrations of the critical five amino acids (CFAAS) glutamine, arginine and BCAAs (leucine, isoleucine and valine) are major advancements in protein supplementation designed to increase the anabolic effects of protein. PROBOLIC-SR provides a continual supply of the most critical amino acids to help stimulate muscle growth, improve recovery and decrease catabolism.+ Amino acids are the building blocks for muscle tissue. In order to achieve maximum muscle growth, you must have an adequate supply of amino acids to feed your muscles. PROBOLIC-SR's bio-efficient protein matrix of whey concentrate, soy isolate and casein is precisely formulated to supply all nine essential amino acids plus high levels of the Critical Five Amino Acids. Aside from providing a high concentration of amino acids, this protein matrix also provides a fast, medium and slow "release profile," which improves bioavailability, nitrogen retention and prolongs it's anabolic effects.+ The Exclusive Sustained Release Micro-Feed Technology further enhances the "release profile" and provides an extended supply of amino acids. This controlled sustained release of amino acids to your muscles creates the ideal anabolic/anti-catabolic state for maximum muscle growth. PROBOLIC-SR's Micro-Feed Technology makes it more bioeffecient and unlike any other protein available.+  PROBOLIC-SR's multi-phase fast, medium, slow and extended release make it the ideal "anytime" protein. The fast acting whey and long lasting protein sources make it perfect for post-workout as it quickly and continually supplies amino acids. It's also perfect to take in between meals to ensure you maintain adequate amino acids to decrease catabolic muscle breakdown and support muscle building.+ Nighttime Growth and Recovery During sleep is when your body builds and repairs muscle tissue. Sleeping the necessary 6 to 8 hours without being able to feed your muscles can create an unfavorable catabolic environment. PROBOLIC-SR's exclusive sustained release technology continually feeds your muscles throughout the night to decrease muscle breakdown and help enhance muscle building and recovery.+ +Within the normal range.
