If you are serious about putting on size, you need energy to train and carbs to grow.* Whether you're a hard gainer, or simply trying to add lean muscle to your physique, sometimes the training isn't enough. A diet that supports growth, and supplements that help the body maximize its potential are crucial for success.* Why Carbs? When you are training to put on mass, carbohydrates are a MUST. They play a vital role in fueling your body for intense exercise and are critical for replenishing your glycogen stores after a workout. Carbohydrates create the optimal environment for building mass by spiking insulin levels, which helps shuttle creatine and essential nutrients to the muscle to support muscle repair and overall growth. An optimal dose of the right carbohydrates can create an insulin spike.
