Xtend is the ultimate, sugar-free, BCAA-containing drink mix to be consumed during exercise (intra-workout).
Whether you're a physique athlete, strongman, powerlifter, traditional athlete (e.g., football, basketball, baseball, soccer, etc), endurance competitor, or just looking to significantly change your body composition through resistance training and nutrition, Xtend is ideally formulated to maximize training intensity and support your goals. Xtend was the first and has become the most well-recognized and used intra-workout catalyst product because it not only works... but it tastes great too!
Xtend contains an incredible:
7000 mg of BCAAs in an ideal 2:1:1 ratio of leucine:isoleucine:valine
3500 mg of leucine
2500 mg of glutamine
1000 mg of citrulline Malate
1171 mg of electrolytes
640 mcg of vitamin B6
And, zero carbohydrates or sugar
Xtend was recently reformulated to dramatically improve taste and ingredient solubility - Xtend is now spoon-mixible - and to provide added functionality for workouts or events under the most grueling of conditions. Xtend is available in 6 mouth-watering, refreshing fruit flavours to make every workout an incredible one.
Q: Who should use Xtend?
A: Xtend was designed to be used effectively by anyone, male or female, who want to perform at their best - from serious athletes to anyone that's just serious about performance or changing their physique. Though ideal for strength or bodybuilding training, or for persons on a reduced carbohydrate diet, Xtend can also be used very effectively in a "bulking phase" or by endurance athletes during training and competition. That is, Xtend works whether it's used as formulated and indicated, or whether you choose to combine Xtend with supplemental carbohydrates based upon performance needs and duration.
Q: How does Xtend work?
A: Xtend is formulated with a precise PentActive blend of key ingredients, synergistically involved in cellular processes to optimize muscle performance and response:
Stage 1: 7000 mg of BCAAs, in a 2:1:1 ratio of leucine:isoleucine:valine is used to provide metabolic energy while you train, as well as to stimulate muscle protein synthesis.
Stage 2: 2500 mg of Glutamine is used to increase extracellular concentrations of Glutamine, which helps to promote muscle intracellular BCAA metabolism down the correct energy and protein synthesis pathways via the BCAA aminotransferase enzyme.
Stage 3: 640 mcg of Vitamin B6 serves as the rate-limiting cofactor involved in optimal BCAA aminotransferase reactions.
Stage 4: 1000 mg of Citrulline Malate can help support rapid ATP turnover and lactate reabsorption to support higher training volumes at a given exercise intensity. Citrulline also serves as a secondary signal to stimulate muscle protein synthesis, most likely arising from its ability to promote increased blood flow via increase nitric oxide (NO) and/or improving the energy state of a cell by promoting lactate reabsorption.
Stage 5: 1171 mg of an extensively studied Electrolyte blend, consisting of Trisodium Citrate Dihydrate, Potassium Chloride, and Sodium Chloride, help to optimize muscle contractile function and promote cell hydration under the most brutal of conditions.
Q: How does Xtend compare to other products?
A: In both 8-week & 10-week clinical trials, under no or weight-reducing calorie restricted diets, respectively, Xtend has significantly outperformed Whey Protein, Carbohydrates and a 4:1 (Carb-to-Protein) sports beverage on measures of lean body mass, body fat, upper- and lower-body muscular endurance, and upper- and lower-body strength. Within the physique and anaerobic sports nutrition industry, competitive products are either under-dosed, contain irrelevant ingredients included more for a label effect than a physiological one, or are so ignorantly formulated as to wonder what species' metabolism the company's R&D personnel believes to be their core audience. During exercise beverages for the endurance world, on the other hand, still depend too heavily on simple carbohydrates or, when amino acids are included, generally use low doses of a whey protein concentrate that yield only a fraction of the key amino acids and introduce unnecessary lactose and fat into a high-performance environment.
Q: Are there any other products that will help improve the results I achieve when using Xtend?
A: Xtend was formulated, and then recently reformulated to remove the need for additional ingredients while you train or compete. However, Xtend was explicitly formulated to contain no carbohydrates or sugar so that you could dictate how you may want to manipulate your carbohydrate needs based upon your training cycle or duration. Therefore, when carbohydrates are desired, combine Xtend with up to 0.45 g of carbohydrate per pound of bodyweight, per hour of exercise. When carbohydrates are added, increase the amount of water used per serving so that the finished formula concentration is easily digestible during exercise.
