    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 with an ideal balance of lean muscle and fat stores. All American EFX i-Rush 475 is a highly sophisticated insulin mimicking formula with a synergistic array of five powerful insulin supporting compounds that achieve the ideal timing and degree of insulin response. Carefully divert anabolic nutrients into muscle cells when you need it most.

    i-Rush 475 is packed with ingredients that affect glucose absorption[1] and divert excess calories to muscle cells preferentially over fat stores.[2] Compounds such as Karbolyn and Banaba leaf help to convert stored fat into energy[3] and pack muscles with stored glycogen,[4] promoting greater muscle fullness and endurance.[5] Rapidly shuttle creatine, amino acids, and other key nutrients into hard working muscle tissue.

    i-Rush 475 contains only naturally occurring nutrients found in foods and plant extracts, with absolutely no drugs or artificial ingredients. i-Rush 475 is carefully designed to increase the positive effects of insulin without increasing overall insulin levels throughout the body, This means greater fullness, pumps, and vascularity without added fat stores.

    For increased glycogen being pushed into muscles cells without the fat-storing effects of insulin, choose i-Rush 475 for the ideal balance of muscle-building insulin benefits.

    Featured Ingredients

    Gymnema Sylvestre – Gymnema sylvestre is a tropical herb commonly used as a natural treatment for diabetic symptoms. It has been suggested to enhance insulin response, which may decrease blood glucose and improve the diversion of calories and carbohydrates to muscles instead of fat stores.

    Karbolyn – Karbolyn is a homopolysaccharide (relatively complex carbohydrate) composed of monosaccharides. Karbolyn quickly absorbs into the bloodstream like a simple sugar, but without the typical crash or spike. It is suggested to be absorbed 18.21% faster than pure dextrose.

    Cinnulin PF – Cinnulin PF is a proprietary water soluble extract of cinnamomum burmannii from cinnamon. Cinnuln PF has been suggested to support a decrease in fasting blood sugar, support lower body fat, enhanced muscle mass, lower blood pressure, and higher antioxidant capacity.

    Chromium Picolinate – Chromium is a mineral whose role in the body is critical: without it, insulin would not work. Chromium supports the proper function of insulin to support its effects on controlling blood sugar levels, carbohydrate storage as glycogen, and metabolism of fat and protein.

    Banaba Leaf – This small tree grown in southern parts of Asia yields a leaf commonly used in folk medicine to treat symptoms of diabetes. Banaba is suggested to interact with glucose and insulin to maximize nutrient uptake and balance blood sugar levels.

    Q. What Should I Expect from i-Rush 475?

    A. i-Rush 475 aids in increasing the amount of glycogen being pushed into muscle cells, making them larger with a higher capacity for endurance and strength. Users typically report their muscles feeling tighter and more “pumped” during intense training within as little as 5-7 days of regular use with i-Rush 475.

    Q. Is American EFX a Company I Can Trust?

    A. American EFX designs all their products with passion and care. They take what you put into your body as seriously as you do! Everything is quality and purity tested before, during, and after production to isolate a premium product free of contaminants. i-Rush 475 is made in a cGMP certified facility and made with rigorous attention to detail.

    Q. How Does i-Rush 475 Work?

    A. i-Rush 475 is designed to support your own body’s natural insulin response. It is composed of safe, natural, and legal compounds that support and enhance the benefits of insulin. By doing so, i-Rush 475 helps to rapidly shuttle powerful ingredients, calories, and nutrients to muscles, where they can ignite protein synthesis and be stored as glycogen.

    Q. Why is Insulin Important?

    A. 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. One potential drawback of insulin elevation is that it can cause increase undesirable body fat – making timing and management of insulin elevation critical! That’s why i-Rush 475 was designed to increase the positive effects of insulin without the negative effect on fat burning.
