3-XL (formerly called CE-XL) is the most advanced creatine ester formula developed. 3-XL is an advanced Tri-Strength Creatine Complex, developed by the researchers at iSatori, to help increase muscular size, strength, and hardness. Within one week, you'll experience greater muscular fullness, crush your current training plateaus, and carry a "pump" around the gym that makes other guys seethe with envy. The combination of active compounds, found only in 3-XL, is called the Tri-Strength Creatine Complex. This is an exclusive blend of creatine ethyl ester, creatine monohydrate, and di-creatine malate, which are the most superior forms of creatine substances available. To that, di-arginine malate was added as a natural biological precursor for nitric oxide, to aid in the delivery of creatine and improve blood flow. 3-XL also contains a precise blend of histidine, carbohydrates, sodium, and chloride to aid in the rapid transport of the nutrients into the muscular plasma and enhance creatine absorption and storage even higher. Creatine Monohydrate is one of the most widely used performance-enhancing supplements on the market, creatine has been the subject of over 200 studies. These studies have shown definite positive effects for muscle building, enhanced cellular energy capacity, and reduced muscle fatigue. Beyond its muscle-building and performance-enhancing effects, creatine has been shown to increase fat loss and have positive effects on overall health by reducing cholesterol and triglyceride levels and improving blood-sugar metabolism.
