Athletici Edge Nutrition IntraXCell


The Original DEDICATED Beta-Alanine, Carnosine Boosting Formula

When You Think of Beta-Alanine, We Dare You NOT to Think of IntraXCell!

Backed by THREE research studies and a track record of FIVE years in the market place; when it comes to beta-alanine supplementation, there is no more of a trusted name than IntraXCell®.  

Increases Muscle Mass, Strength & Endurance! 

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:
(As supported by THREE research studies)

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 just how IntraXCell’s ingredeints 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 utilizing a researched dose of beta-alanine, that dramatically boosts 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 along with carnosine to combat fatigue causing, free radicals. 

How do the other key ingredients in IntraXCell’s formula work with the beta-alanine content and support intracellular carnosine levels?

One of carnosine’s attributes beyond stabilizing muscular pH, is its ability to act as an intracellular antioxidant that can fight cellular fatigue. Knowing these secondary benefits of carnosine, we have combined other ingredients with beta-alanine that have the ability to boost yet another  powerful intracellular antioxidant called glutathione. At the same time, the IntraXCell formula can directly work with carnosine’s antioxidant ability.

  1. N-Acetyl-L-Cysteine (NAC) - NAC increases glutathione levels inside the cell which is a power antioxidant that fights cellular fatigue. Interestingly beta-alanine has now been shown to increase the synthesis of glutathione by increasing the availability of its precursor cysteine. Beta-Alanine and NAC work perfectly together.
  2. Vitamin E – Vitamin E has been shown to increase carnosine levels more than carnsoine alone. Carnosine has been shown to increases Vitamin E antioxidant ability. These two operate hand in hand.
  3. Alpha-Lipoic-Acid – alpha-lipoic-acid is a highly versatile antioxidant that boosts the above other two antioxidants, vitamin E and the end result of NAC supplementation,(boosted glutathione levels).

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: Who can benefit from IntraXCell?

  • Bodybuilders, High Intensity Cross Trained Athletes, Runners, Cyclists, MMA Fighters and sport specific training that require both strength and endurance.
  • 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: 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 THREE research studies
  • 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 licenses CARNOSYN®, the PATENTED brand of beta-alanine, insuring the highest quality and is the beta-alanine used in the majority of studies.
  • IntraXCell is designed with no stimulants so it can be taken anytime during the day everyday including late night workout sessions.
  • 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: What other supplements do you recommend to maximize the results when taking IntraXCell?

  • We recommend our Intra-Workout formula IntrAbolic, that is perfectly designed to work with IntraXCell. Think Peanut butter and jelly with these two products, one should not be without the other
  • Our premium pre-workout formula, PreSurge Unleashed is recommended to complete this insanely effective muscle building, performance stack.

Q: Are there any stimulants in IntraXCell?


Q: Can I take IntraXCell late at night?


Recommended Use: As a dietary supplement, take one serving twice daily. IntraXCell may be taken with or without food--food may dampen the prickling/flushing effect that some people experience from Beta-Alanine. On training days: Take one serving 15-20 minutes prior to exercise (can be conveniently taken with our Pre-Workout formula PreSurge) and take one serving post-workout. If you are stacking IntraXCell with IntrAbolic, on days you take IntrAbolic, only take ONE serving of IntraXCell post-workout.

On non-training days: Continue to take two servings daily with food. For best results, use IntraXCell daily for a minimum of one month to optimize intracellular muscle carnosine levels. Performance benefits from IntraXCell will become noticeable in your workouts within 1-2 weeks, and will continue to become stronger for the first three months as intracellualr carnosine levels continue to increase. To fully maximize IntraXCell’s benefits, we recommend individuals stay on IntraXCell for atleast a three month cycle.
