Muscle growth: YK-11 is believed to stimulate muscle growth leading to bigger and stronger muscles. It might promote protein synthesis that is important during healing of injured muscles.Selective Anabolic effects: People who have used YK-11 report having profound anabolic effects which are comparable with typical trainers. These properties encourage rapid muscle development.Increased Muscular Density: According to some studies, YK-11 enhances musculature especially those parts that need sculpting into detailed cuts sought by many bodybuilders. May Improve Bone Density: Preliminary study results suggest that usingYK-11 could improve bone density and overall bone strength.
