EAS Phosphagen XT

For gains in strength and mass, creatine has earned the reputation as "the one that works," substantiated not only by rigorous university research, but also by "real world" results over the past decade1. As the next step in creatine supplementation, the main challenge today is providing for optimal creatine transport to muscle so that it can act to facilitate the immediate energy needs of high-intensity exercise. The first breakthrough in promoting creatine storage was the addition of carbohydrates, as this has been shown to boost insulin-mediated creatine storage by 60%2. Since that revolution, the only major "improvement" in creatine transport has been the addition of more and more sugars, which means additional empty calories that likely convert into unsightly bodyfat, or cause gastrointestinal distress.

Phosphagen XT takes creatine transport to the next level with the addition of 4-hydroxyisoleucine, a compound that facilitates creatine transport by potentiating sugar-induced insulin secretion. This means that one can experience unsurpassed creatine transport with fewer sugars. Further, this compound may also increase creatine entry into muscle cells, as research indicates 4-hydroxyisoleucine may increase insulin sensitivity3. Ultimately, this means faster gains in muscle development and athletic performance while maintaining leanness.

Why does this product include taurine?
Taurine is known as the "insulin-mimicking" amino acid. This amino acid may further assist delivery of creatine into muscle cells.

Do I need to load with Phosphagen XT?
Due to the efficient delivery of this product and high amount of creatine per serving, loading should not be necessary.

Should I cycle Phosphagen XT?
Most research indicates there is no benefit to cycling creatine. As a general rule, take creatine products only during training phases when you are trying to bulk up or increase strength.

How is Phosphagen XT different from other creatine products?
With the inclusion of the unique, patent-pending product 4-hydroxyisoleucine, Phosphagen XT offers the most advanced delivery system yet, and includes far less sugar than leading competitors.

What is 4-hydroxyisoleucine?
4-hydroxyisoleucine is an amino acid extract from fenugreek seed. Research shows that taking 4-hydroxyisoleucine with carbohydrates causes a greater rise in insulin than is normally encountered with carbohydrates alone. Since insulin is the key driver of creatine into muscle cells, 4-hydroxyisoleucine is the perfect product to accelerate creatine storage.

What is the benefit of the three-stage carbohydrate blend?
EAS researchers formulated the three-stage carb blend to precisely manipulate insulin, the hormone responsible for nutrient delivery and storage. More circulating insulin means that the body can more effectively deliver creatine to muscle cells, where it can act to increase size and strength. The first stage is dextrose, a high-glycemic sugar that initially sets insulin in motion. Next, maltose, an even higher glycemic sugar, further spikes insulin to facilitate creatine storage. Finally, potato starch is included to "smooth out" the action of insulin. This carbohydrate blend is essential for the action of 4-hydroxyisoleucine. The synergistic combination of 4-hydroxyisoleucine and carbohydrates creates an optimal environment for creatine delivery, and thus muscle gain.
