Product Description

The World's First Beta-Alanine, Carnosine Boosting Formula In Convenient Capsule Form! Boost Strength And Increase Lean Muscle Gains With IntraXCell!

History Is About To Be Made Once Again!

Until now, creatine, with numerous research studies to support its effectiveness, was the leading supplement for improving exercise and muscular performance. Since creatine made its explosion into the sports nutrition world in the early nineties, our understanding of exercise physiology and sports nutrition has evolved exponentially. Recent research is giving rise to another supplement breakthrough-one that will change the direction of the industry like creatine did so many years ago. The research supported, IntraXCell is the next breakthrough supplement for increasing explosive strength, muscle mass and endurance.

IntraXCell Highlights:

• Boosts Explosive Muscular Strength & Power Output.
• Increase Muscle Mass.
• Increase Anaerobic Muscular Endurance.
• Increase Aerobic Endurance.
• Delay Muscular Fatigue - Train Harder & Longer
• Increase Muscle Fullness and Vascularity
• No Bloating or Water-Retention

While other supplement companies talk a big game, making unsubstantiated claims with no scientific support, Athletic Edge Nutrition is different. We are a new breed of supplement company. We raise the standard, by placing our exact formula (IntraXCell) through the rigors of a scientific research study. In doing so, we want to prove to you that Athletic Edge Nutrition IntraXCell delivers the promised results and will meet and exceed your highest expectations!

A research study, on 18 collegiate wrestlers using IntraXCell for 8 weeks, has just been completed. The results were staggering. IntraXCell caused huge increases in anaerobic strength, power and muscular endurance!

How does IntraXCell work?
While beta-alanine is largely responsible for the majority of performance benefits you gain from IntraXCell, there are other contributing factors to the science of IntraXCell. First, we will discuss some key issues occurring during exercise that limit us from reaching our strength and muscle mass goals. We will then explain how IntraXCell effectively targets these limitations.

What stops us from making new muscle gains, big increases in strength and limits us from reaching our full potential?

The sequence of events looks like this:
1.Our energy systems release large amounts of hydrogen ions(H+) during high intensity exercise.
2.H+ cause fatigue and cause your muscles pH to drop (become more acidic)
3.As our muscles pH quickly drops, so does your strength, while muscular fatigue increases
4.At the same time, fatigue causing free radicals are increased with exercise.
The Result of these events: Strength plummets, fatigue sets in and muscles are not adequately worked. Without sufficient overload, your muscles cannot and will not grow.

How can IntraXCell combat these events?
1.By dramatically boosting the levels of a powerful H+ buffer inside our muscles called carnosine.
2.Carnosine is a naturally occurring di-peptide that has the ability to stabilize muscular pH by soaking up (H+)
3.Carnosine is found in both type I and type II muscle fibers, but is highest in type II muscle fibers. Type II muscle fibers are primarily used in high intensity strength workouts and are most responsive to muscular growth.
4.By increasing carnosine concentrations in type II muscle fibers, you greatly enhance their ability to buffer/absorb increased amounts of H+ that are released during exercise.
5.Includes the antioxidants NAC, ALA and Vitamin E, which work synergistically along with carnosine to combat fatigue causing, free radicals.
The End Result: IntraXCell keeps us in an optimal pH range by buffering/absorbing H+, while simultaneously fighting fatigue-causing, free radicals. In doing so, our muscles are able to perform at much higher levels.

Frequently Asked Questions

Q: There are a few other beta-alanine, carnosine boosters out there, what makes IntraXCell different?
• IntraXCell was the world's first dedicated beta-alanine, carnosine booster in convenient capsule form.
• IntraXCell is the first and only stand alone beta-alanine formula that is backed by a research study.
• With IntraXCell, you get a large 4 gram dose of Beta-Alanine per day complying to the actual dosage used in the scientific research. Other carnosine boosters put beta-alanine in proprietary blends and do not list the amount, so it's impossible unless the company discloses the actual beta-alanine content for you to know if you are really getting a high enough dose to build up carnosine levels and reap all the benefits!
• IntraXCell is designed with no stimulants so it can be taken anytime during the day everyday including late night workout sessions. At Athletic Edge Nutrition we do no recommend taking stimulants everyday, so putting any stimulants in IntraXCell or any Carnosine booster would not be logical from our standpoint.
• IntraXCell is a true carnosine booster without the unnecessary fluff that's added to some of the other carnosine boosters currently on the market.

Q: Who can benefit from IntraXCell?
• Individuals participating in weight training looking to gain lean muscle mass and increase strength.
• Any individual involved in athletic activities where strength, power and muscular endurance are needed.
• Active individuals who have reached a training plateau and are looking for something to take them to the next level.

Q: How long will it take for me to start noticing benefits?
• Performance benefits typically start occurring in as little as two weeks, although some individuals will notice benefits within one week. As carnosine levels continue to increase, so will the benefits. The most dramatic results are generally experienced within the 3-4 week range, but they don't stop there. Recent research is now showing carnosine levels continue to increase up to at least 12 weeks, so the benefits just keep on getting better which is why we recommend to continuously stay on IntraXCell for at least 3 months to optimize your carnosine levels.
• Immediate benefits: Many users experience intense vasodilatation/pumps from the very first time they take their first does of IntraXCell. The reason this occurs is because Beta-Alanine increases carnosine and carnosine is a powerful precursor in generating nitric oxide synthase (NOS). NOS are a group of enzymes necessary for making the powerful vasodilator nitric oxide. Take IntraXCell with SteelEdge prior to exercise and let us know your experience. We are confident that you will be very pleased pumps/vasodilatation from your very first workout.

Q: What other supplements do you recommend to maximize the results when taking IntraXCell?
• We recommend our Full Spectrum Pre-Workout Formula, SteelEdge. SteelEdge contains many ingredients that may work synergistically with IntraXCell. On training days, take IntraXCell with SteelEdge to amplify the benefits of each product.
• Creatine is another supplement that may work synergistically with IntraXCell and they can certainly be stacked together.

Q: Are their any stimulants in IntraXCell?

Q: Can I take IntraXCell late at night?

Effects of beta-alanine supplementation on exercise performance during a competitive wrestling season: An 8-week open label study

The goal of wrestlers during a competitive season is to maintain or lose body weight without compromising athletic performance. However, some studies have reported decrements in exercise performance associated with weight loss and/or the strain of a competitive season. The purpose of this study, therefore, was to examine the effects of 8 week beta-alanine (b-ala) supplementation on exercise performance in Division II collegiate wrestlers during a competitive season.

25 college wrestlers (age 18 to 22 y) volunteered to participate in this study, and 18 subjects completed the study. Each participant ingested 4 g/d of b-ala in an open-label manner during the final eight weeks of their competitive season. The subjects followed a standard training protocol for collegiate wrestling as dictated by the head coach. They were also required to maintain uniform body mass during the entire eight weeks, as per weight bracket allowance during the competitive season. Before and after supplementation, subjects performed a 400 m sprint and 90 degree flexed-arm hang to exhaustion. Immediately prior to and following the pre treatment and post treatment 400 m sprint, subjects blood lactate was taken via finger stick and analyzed to determine lactate increase during the 400 m sprint.

The subjects showed significant decrease (p<0.01) in 400 m sprint time and significant increase (p<0.01) in 90 degree flexed-arm hang No significant change (p>0.05) in blood lactate values were observed.

The results of our study suggest that supplementation of b-ala may improve exercise performance in wrestlers during a competitive season. Because of the design of this experiment, it is impossible to identify exactly how much of the positive effects experienced by the subjects was a direct result of the supplementation. However, due to the large increase in performance and the similarity of results in comparison to other b-ala studies, we feel our study strongly suggests efficacy of b-ala supplementation. The ergogenic effects of b-ala supplementation during a competive wrestling season needs to be confirmed in placebo-controlled trials.

Ergogenic aids, or substances and methods that enhance exercise performance, are as ancient as sports themselves. Nutritional ergogenic aids are known from ca. 500-400 B.C., when athletes and warriors used products such as deer liver and lion heart to impart certain performance benefits. In modern times, athletes have focused on "high-tech" dietary supplements, such as creatine monohydrate and post-exercise recovery drinks. The latest addition to our ergogenic arsenal appears to be b-alanine (b-ala), a nonessential amino acid that is found in many foods we eat. Recent studies have demonstrated that oral b-ala supplementation increases muscle carnosine content by ~ 60-80%. Carnosine, a dipeptide composed of the amino acids beta-alanine and histidine, has anti-fatigue properties, which are likely related to its ability to buffer increased muscle acidity following high-intensity exercise. High H+ concentration is thought to play a key role in muscular fatigue.

Sprinting distances of 400 m to 800 m closely mimics the metabolic demands experienced during a collegiate wrestling match, and could be considered anaerobic in nature. Likewise, the intensity of muscle contraction required to hang from a bar with elbows flexed at 90° is similar to that of holds performed by wrestlers during a match, and when performed to failure, is highly anaerobic (20 s to 2 min). In order to be successful, wrestlers must maintain or lose bodyweight throughout the competitive season without compromising athletic performance. However, extreme weight reduction methods commonly used by competitive wrestlers and the physical demands of training throughout the competitive season tend to impair exercise performance.

The purpose of this study was to examine the effect of 8 week b-ala supplementation on 400 m sprint time, 90° flexed-arm hang time, and blood lactate accumulation (during 400 m sprint) of Division II collegiate wrestlers during a competitive season. Our study did not utilize a placebo controlled design due to the fact that the subjects were involved in their competitive season.


25 NCAA Division II collegiate wrestlers (age 18 to 22 y) volunteered for this study, and 18 completed the study. 5 subjects did not complete the study due to attrition from the wrestling team, while 2 subjects could not complete the testing due to injury. The school's Institutional Review Board approved all procedures prior to the initiation of the study. Each subject was informed of potential risks of participating in the study and gave written consent before participation. No subjects reported using sport supplements or other performance enhancing substances.

Nutritional Protocols
During the study, subjects were asked to maintain their current diet and abstain from using any dietary supplements or medications. They were also required to maintain uniform body mass during the entire eight weeks, as per weight bracket allowance during the competitive season. Following pre-testing, subjects were issued a 4 week supply of a b-ala supplement (IntraXCell, Athletic Edge Nutrition, Miami, FL), and a folder containing an 8 week dosing register, and an 8 week journal template with 2 entries per week. A daily serving (6 capsules) of this supplement provided 4 g of b-ala, a 402 mg proprietary blend of N-acetylcysteine/a-lipoic acid, and 15 mg of vitamin E (d-alpha tocopherol acetate). Subjects were issued the second 4 week supply of the b-ala supplement following the first 4 weeks of the supplementation period. Subjects were instructed to ingest 6 capsules of the b-ala supplement per day, in three equal doses (i.e., 2 capsules 3 times daily), and record the exact day and time of dose in the dosing register.

Exercise Protocols
In both pre and post testing, subjects were encouraged to run as fast as possible in the 400 m sprint and hang as long as physically possible during the flexed-arm hang. All tests were administered by the same technicians in both pre and post testing, and identical protocols were followed in each, including time of day and day of the week. Prior to sprinting continuously 400 m, subjects resting blood lactate was taken via lactate test strip analyzer (Accusport Portable Lactate Analyzer). Subjects were timed in the 400 m sprint using a hand held stopwatch. Immediately following the 400 m sprint, subjects? blood lactate was again taken using identical procedure and equipment as before the sprint.

Approximately 7 hours after testing 400 m sprint and blood lactate, subjects were required to hang from a straight 1 diameter bar. Subjects were instructed to use an underhand grip and maintain 90° flexion at the elbow joint for as long as possible. The degree angle was ensured by the technician's visual assessment. This was aided by using a 6° triangle square placed on the subject's flexed elbow and drawing two perpendicular lines at 90° on the subjects arm with permanent marker. This method is consistent with the research conducted by Clemons et al. indicating the undergrip 90° flexed-arm hang as a valid test of weight-relative strength, and eyeballing the 90° angle as a reliable test-retest practice. The subjects time started at the moment the body was suspended and ceased the instant 90° elbow flexion was compromised. Time was measured using a hand held stopwatch.

Statistical Analysis
Mean and standard deviation were calculated for change in lactate during the 400 m sprint (LA?), 400 m sprint time, and 90° flexed arm hang time. The mean of each descriptive statistic was tested for significance from pre to post test using a dependent t-test. Significance was accepted at a level of p = 0.05.

Mean 400 m sprint time during the pretest was 68.24 seconds 3.523 seconds and the mean 400 m sprint time during the post test was 64.82 seconds 3.370 seconds (Figure 1) This change was accepted as significant with p = .000. Mean flexed-arm hang time time in the pretest was 58.48 seconds 3.184 seconds and mean flexed-arm hang time time posttest was 67.00 seconds 3.888 seconds (Figure 2) This change was also accepted as significant with p = .000. Mean LA? during the pretest was +2.964 mmol/l 2.335 mmol/l and mean LA? during the posttest was +2.975 mmol/l 1.978 mmol/l (Figure 3) This change was determined to be non-significant, as p = .791. One subject reported frequent gastrointestinal discomfort during the supplementation period. However, it is unclear whether supplementation contributed to this condition.

Collegiate and other competitive wrestlers often utilize calorie restriction and dehydration in order to manipulate body weight for the purpose of qualifying in their respective weight allowance bracket. Collegiate wrestling places great strain on the musculoskeletal system throughout a competitive season. Extreme weight reduction/maintenance practices combined with the strain of a competitive wrestling season tends to decrease athletic performance, often quite dramatically. Despite the fact that our subjects were examined during the competive season, the results indicated clear improvements in wrestling-related performance tests, including 400 m sprint and 90° flexed arm hang time. 400 m sprint closely mimics the metabolic demands experienced during a collegiate wrestling match. Likewise, 90° flexed-arm hang is similar to that of holds performed by wrestlers during a match.

Our study did not utilize a placebo controlled design due to the fact that the subjects were involved in their competitive season. The coach of the team did not desire to have the potential for discrepancies in performance during the competitive season, yet the researchers sought the need to experiment on the subjects during the competitive season in order to assess whether b-ala supplementation could augment exercise performance under conditions that may inhibit performance. Because of the design of this experiment, it is impossible to identify exactly how much of the positive effects experienced by the subjects was a direct result of the supplementation. However, due to the large increase in performance and the similarity of results in comparison to other b-ala studies, we feel our study strongly suggests efficacy of b-ala supplementation.

It was our intent to focus on the practical application of this product during the most physically demanding time of the year, the competitive season. It is important to note that the subjects in this study had already completed their off-season and pre-competition training. Additional large improvements in execise capacity during the competitive season are not typical in any sport, especially wrestling where calorie reduction and dehydration are common practice. Therefore, the fact that b-alanine supplementation resulted in large improvements in exercise performance has added significance.

It is likely that b-ala supplementation increased buffering capacity due to elevated muscle carnosine concentrations. However, muscle buffering capacity or muscle carnosine content was not measured in our experiment. Other recent studies have demonstrated that b-ala supplementation increases muscle carnosine content by ~ 60-80%. The pK value of carnosine is 6.9, suggesting it is an ideal buffer at physiological pH. Based on data from muscle biopsies, sprint running significantly decreases intramuscular pH from 7.0 at rest to < 6.5 post-exercise. At this level of pH, the increased H+ concentration may inhibit several vital processes required for muscle contractions to continue at desired power output. Most of the studies which have shown strong evidence of the effect pH on muscular fatigue have been conducted at relatively low temperatures (< 15 °C), while warmer temperatures that approach physiological temperatures (30 °C) show much less of an inhibitory effect of pH. Thus, the role of pH in fatigue is controversial. Carnosine, however, has other important roles, including antioxidant activity, a metal chelator, a Ca2+ and enzyme regulator, an inhibitor of protein glycosylation and protein-protein cross-linking. These actions may also affect exercise performance.

In this study, supplementing with b-alanine had no significant impact on blood lactate accumulation during 400 m sprint. During short-term, high-intensity exercise, lactate accumulates as a result of lactic acid production being greater than its removal. Since lactic acid dissociates a H+ at physiological pH, most exercise physiology textbooks tell us that lactate accumulation is associated with acidosis. However, Robergs et al. have argued that lactate production actually retards, not causes, acidosis. They feel that exercise-induced acidosis is caused by an increased reliance on nonmitochondrial ATP turnover. Thus, it is unclear what is the true meaning of blood lactate measurement.

The b-ala supplement used in our study also provided a 402 mg proprietary blend of N-acetylcysteine/a-lipoic acid and 15 mg of vitamin E. N-acetyl-cysteine is an effective scavenger of free radicals as well as a major contributor to maintenance of the cellular glutathione status in muscle cells. There is some evidence that N-acetyl-cysteine supplementation can delay muscular fatigue. However, these studies used much larger doses of N-acetylcysteine than provided by the supplement used in our study. Lipoic acid is characterized by high reactivity towards free radicals and is capable of regeneration of vitamin C and E. Also, it elevates tissue levels of glutathione. While increased tissue levels of glutathione and supplemental vitamin E may offer some health benefits for athletes, it is likely that b-ala was the main driving force behind the ergogenic effects.

Although our study is limited by its open-label design, the strengths of this study are as follows: 1) a highly homogeneous study population; 2) the measurement stability, which resulted from the maintainance of uniform body mass during the entire eight weeks; 3) tests were performed on highly trained individuals, reducing the chance of the training effect skewing the results; 4) the subjects had already completed their off-season and pre-competition training prior to taking the tests, which pretty much nullifies the training effect variable; 5) the age range, activity level and gender of the subjects are very relevant to the typical individual who would be using this type of ergogenic supplement. Thus, the findings of this study may be useful for sports nutritionists, strength coaches and athletes who are looking for a legal and well-tolerated dietary supplement that can improve anaerobic exercise performance.

The results of our study suggest that supplementation of b-ala may improve exercise performance in wrestlers during a competitive season. Specifically, the subjects showed significant decrease in 400 m sprint time and significant increase in 90° flexed-arm hang. However, the ergogenic effects of b-ala supplementation during a competive wrestling season needs to be confirmed in placebo-controlled trials.
