Most people are familiar with the famous "Insulin Spike" and its ability to shuttle anabolic nutrients, such as glucose, creatine and amino acids into muscle cells. However, the biggest drawback is that insulin elevation can also cause an increase of undesirable body fat. That's why the timing and management of insulin elevation is critical! A properly built 'insulin-mimicking' supplement should not only provide you with all the muscle-building benefits of insulin but also help promote healthy body composition at the same time. For example, since high insulin levels during your workout can decrease the amount of fat you burn, taking an insulin mimicker pre-workout may provide benefits similar to insulin but without the negative effect on fat-burning. And that's why i-RUSH 475 was designed to support the positive effects of insulin without increasing overall insulin levels within the body. Despite its amazing effectiveness, you should know i-RUSH 475 only contains nutrients that naturally occur in many foods. There are absolutely NO drugs or artificial ingredients in i-RUSH 475. What should I expect from i-Rush? Users typically report that within as little as 5-7 days of regular use, their muscles feel tighter and get even more "pumped" during intense training. Our researchers believe this occurs because i-RUSH 475 aids in increasing the amount of glycogen being pushed into muscle cells, helping make them larger and stronger.
