Product Information:
Optimum Nutrition's CGT-10 is an advanced formula that combines three of the most effective ingredients available: Creatine, Glutamine & Taurine. Each serving provides 5 grams of CreaPure(tm) brand Creatine Monohydrate, 3 grams of L-Glutamine and 2 grams of Taurine.Creatine is bodybuilding's ultimate supplement, and for good reason. For one thing, creatine can significantly increase lean muscle mass in just two weeks. It is also responsible for improving performance in high-intensity exercise, increasing energy levels, and speeding up recovery rates. It's no wonder athletes who use it have such of an edge over those who do not. Soon nearly every athlete who competes will use it (if they don't already). Creatine's ability to enhance energy reserves in muscles comes from its muscle protein synthesizing action, while minimizing protein breakdown. This occurs because creatine has the awesome effect of super-hydrating muscle cells with water. It enhances muscles' growth too-making muscle fibers bigger and stronger.Glutamine is highly in demand throughout the body. It is used in the gut and immune system extensively to maintain optimal performance. 60% of free-form amino acids floating in skeletal muscles is L-glutamine. L-glutamine plays a very important role in protein metabolism, and it appears to be a very important nutrient for body builders. When supplemented, it may help body builders reduce the amount of muscle deterioration that occurs because other tissues that need glutamine will not rob the glutamine stored in the muscle cells.

Pacific Health Laboratories Endurox R4 - Tangy Orange
Speed Up Muscle Recovery And Reduce Muscle Damage Following Exercise!Endurox R4 Recovery Drink was developed by leading exercise physiologists and based on landmark research redefining how the exercising muscle recovers. Endurox R4 contains the patented 4 to 1 ratio of carbohydrate to protein to speed muscle glycogen replenishment and rebuild muscle protein after exercise, antioxidants to reduce post-exercise muscle damage and glutamine to help reduce muscle stress. Recover faster Recover better Come back stronger Optimal carbohydrate profile with less sugarEndurox R4 Clinical StudiesEffects of recovery beverages on glycogen restoration and endurance exercise performance.This study determined that "The rate of [post-exercise] recovery is coupled with the rate of muscle glycogen replenishment," and that "recovery supplements should be consumed to optimize muscle glycogen synthesis as well as fluid replacement." Eight endurance trained cyclists performed two trials consisting of a 2-hour glycogen depletion ride followed by an exhaustive ride at high intensity. Subjects received either a carb-protein beverage (Endurox R4) or a carb-only sports drink immediately and 2 hours post-exercise. Post-exercise ingestion of carb-protein beverage (Endurox R4), in comparison to the carb-only beverage, resulted in a 55% greater time to exhaustion during a subsequent exercise bout at 85% VO2max. Ingestion of the carb-protein beverage resulted in a 17% greater plasma glucose response, a 92% greater insulin response and a 128% greater storage of muscle glycogen compared to the carb-only beverage.Effects Of Recovery Drinks After Prolonged Glycogen-Depletion Exercise.This study found that "recovery from glycogen-depleting exercise was significantly enhanced by [Endurox R4] Recovery Drink when compared to Gatorade. In addition, [Endurox R4] Recovery Drink decreased the formation of final oxidation products, when compared to Gatorade." Eight male cyclists performed a two-hour cycling exercise bout followed by one to three 5-minute sprints. A four-hour recovery period ensued in which the subjects were given 24 ounces of either Endurox R4 or Gatorade. A performance test to exhaustion was then conducted. The recovery phase showed significant increases in both plasma glucose and insulin following Endurox R4 ingestion as compared to Gatorade. There was an average 66% increase in time to exhaustion during the performance ride following Endurox R4 ingestion compared to Gatorade. Final oxidation products following Endurox R4 ingestion were significantly decreased as compared to Gatorade ingestion.The Effect of Two Sports Drink Formulations on Muscle Stress and Performance.This study demonstrated that "A [carb-protein supplement], by providing additional [carbohydrate] and amino acids, may reduce postexercise muscle stress, as evidenced by a 36% decrease in 24-hour [creatine kinase] levels. Ten college-age males and females completed a 45-minute run, rested in a 10-minute transition, cycled for 90 minutes, and then performed a time trial (TT). During the transition and 30 minutes into the bike segment, subjects ingested either a 15% carb-protein beverage (Endurox R4) or a carb-only beverage.. Blood samples were collected and analyzed for creatine kinase (a biomarker of muscle damage), lactic acid and glucose. There was a 36% reduction for the 24-hour post-exercise creatine kinase level in the carb-protein treatment.Effects of Post Exercise Carbohydrate-Protein Supplement On Skeletal Muscle Glycogen Storage.This study showed that "The greater rate of recovery following glycogen-depleting exercise during the [carb-protein] treatment shown [in previous studies] was likely due to a greater glycogen restoration." Eight endurance-trained cyclists performed two trials consisting of a 2-hour glycogen depletion ride followed by ingestion of 12 oz of a carb-protein supplement (Endurox R4) or a carbohydrate supplement immediately and 2 hours post-exercise. Trials were randomized and separated by 7 days. Blood samples were collected prior to exercise and throughout the 4-hour post-exercise recovery period. Muscle biopsies were taken immediately after and 4 hours postexercise for determination of muscle glycogen content. Ingestion of the carb-protein supplement resulted in a 17% greater plasma glucose response, a 92% greater insulin response, and a 128% greater storage of muscle glycogen compared to the carb-only supplement.Carbohydrate protein complex increases the rate of muscle glycogen storage after exercise.This study found that "post-exercise muscle glycogen storage can be enhanced with a carbohydrate-protein supplement as a result of the interaction of carbohydrate and protein on insulin secretion." Nine men cycled for two hours on three occasions to deplete their muscle glycogen. After each workout they drank a carbohydrate, protein, or carb-protein supplement. The rate of muscle glycogen replenishment in the carbohydrate-protein treatment was 38% greater than in the carbohydrate treatment and more than three times greater than in the protein treatment.Carbohydrate-protein drink improves time to exhaustion after recovery from endurance exercise.This study demonstrated that "a [carb-protein] drink following glycogen depleting exercise may facilitate a greater rate of muscle glycogen resynthesis than a [carbohydrate-]only beverage, hasten the recovery process, and improve exercise endurance during a second bout of exercise performed on the same day." Ten male athletes completed a long workout on stationary bikes, then drank either a carb-protein sports drink (Endurox R4) or a carb-only sports drink. After a two-hour rest the subjects completed an endurance bout to exhaustion. The athletes went 20% longer with the carb-protein sports drink than with the carb-only sports drink.Early post-exercise muscle glycogen recovery is enhanced with a carbohydrate-protein supplement.This study showed that "a [carb-protein] supplement is more effective for the rapid replenishment of muscle glycogen after exercise than a [carb-only] supplement of equal [carbohydrate] or caloric content." Subjects completed a very long workout on stationary bikes and then drank either a carb-protein sports drink (Endurox R4) or a carb-only sports drink of equal calories. Four hours later, muscle glycogen was significantly greater in those given the carb-protein sports drink.Postexercise protein intake enhances whole-body and leg protein accretion in humans.This study found that post-exercise consumption of a carbohydrate-protein supplement increased protein synthesis in exercised muscles and throughout the body compared to a carb-only supplement and placebo. Five men and five women completed a one-hour stationary bicycle ride. Upon completion of the workout, subjects were randomly given either the placebo, the carb-only supplement, or the carb-protein supplement. The test was repeated until all subjects had received all three treatments. The carb-protein supplement increased plasma essential amino acids 33%, leg uptake of glucose 3.5-fold, and leg and whole-body protein synthesis 6-fold and 15%, respectively. Whereas post-exercise intake of either placebo or the carb-only supplement resulted in a net leg release of essential amino acids and net loss of whole-body and leg protein, the carb-protein supplement resulted in a net leg uptake of essential amino acids and net whole-body and leg protein gain.References:1.
