The Power

X-Cite continues to carve out its place as one of the most effective pre-workout supplements on the market. Made from the most researched, most effective ingredients in sports nutrition, it’s no wonder why X-Cite is the choice for serious athletes.

The Science

Like everything we do at Athlean-X, our supplement facts panels contain a collection of the world’s best and brightest supplement ingredients. Each one is backed by research and science in sports medicine to ensure you’re getting the most effective dosages and the proper combinations to get real results.

The Facts

You asked and we answered with our most potent formulas and open labels so you know exactly which ingredients and how much of each you’re getting. Athlean-Rx contains no proprietary blends, and as always, no fillers, no substitutes and no harmful chemicals.

The Results

I’ve been working on this formula for well over a year, and I’ve promised to always deliver the same things that I recommend to my pro athletes and that I take myself. I’ve gotten a lot of comments on our YouTube channel about the gains I’ve made over the last few months. I can honestly say these formulas have had a major role in those results and they’re finally here so I can share them with you!

I take my training seriously, that’s why I take X-Cite before every workout.


Beta Alanine



Beta Alanine Increases intramuscular concentrations of carnosine thereby increasing strength, power, endurance and recovery, thereby increasing athletic performance and muscle mass.

  • Increases fat loss and muscle growth
  • Reduces post training session fatigue
L-Citrulline Malate



One of the best benefits of L-Citrulline DL-Malate is enhanced ATP production. This is needed by every living cell in the body and equates to higher energy levels. This is even more important for muscles which are engaged in heavy training or otherwise working. Increased ATP production also leads to the ability to train harder and recover faster.

  • Improves muscle endurance and aerobic performance
  • Boosts energy
  • Increases ATP production allowing for harder training and faster recovery
  • Supports lean muscle mass gains
Creatine HCL

ATHLEAN XCITE CONTAINS: 2g (4g when taken with a stack)


Creatine hydrochloride's main benefit is helping to build muscle faster and easier. This is thought to be due to an increase in the production and supply of ATP to working muscle cells. This also provides more energy to the muscles, helping to avoid lactic acid build-up and allowing for longer and more intense workouts.

  • Increases muscle strength and power
  • Allows for faster and easier muscle growth
  • Is better absorbed than Creatine Monohydrate and does not require a loading phase
  • Reduces muscle damage and post workout soreness



One huge benefit of L-Tyrosine supplementation is that it can be useful for weight loss. It does this by improving some of the neurobiological disturbances typically caused by dietary restrictions. Medical research also indicates that L-Tyrosine supplementation can sharpen the memory, if taken on a regular basis. Tyrosine is able to protect the nerves from toxins and it is even able to cross the blood-brain barrier, which is one of the reasons why it is effective at raising the levels of key neurotransmitters. Another interesting l-tyrosine benefit is it helps the body adjust to situations of cold and fatigue.

  • Supports weight loss
  • Improves memory
  • Regulates hormones



One of the most important benefits of Betaine is its ability to improve muscle strength and power during training sessions. Some studies have shown that it can improve endurance, increase the number of reps that can be done with a given weight, and improve power and force with every rep. Evidence also indicates that Betaine improves protein synthesis following training sessions.

  • Improves muscle strength, power and endurance
  • Increases protein synthesis following training sessions
  • Increases growth hormone and insulin-like growth factor 1 production
  • May help promote fat loss



Brand new studies suggest that Taurine is the most abundant amino acid in the body (above glutamine), particularly in the power generating type II fibers. Through supplementation it is possible to maintain peak stores of this important nutrient to enable more consistent force production without energy dropoff. Long term, taurine has been shown to be a cell volumizer that boosts internal muscle hydration…resulting in higher rates of muscle growth and function.

  • Supports greater muscle growth and function
  • Helps support cardiovascular function
  • Helps temporarily restore mental alertness
  • Assists in periods of increased mental and physical exertion

CLINICALLY EFFECTIVE DOSAGE: 3 - 6mg per kg of bodyweight



Caffeine is a widely used stimulant which is well studied and known to be safe in dosages of up to 500-600 mg. X-Cite provides the perfect amount of natural anhydrous caffeine, to produce unparalleled mental alertness and energy without the jitters or dangerous side effects of other popular pre-workout stimulants.

  • Increases muscle endurance and strength
  • Decreases muscle fatigue during workouts
  • Boosts thermogenesis
  • Improves concentration and short term memory

Vitamin D



Vitamin D has been used to boost athletic performance since 1927. It's especially effective for those who are deficient, which is most everyone. Vitamin D deficiency is related to cancer, depression, Alzheimer's and Parkinson's disease. Getting adequate amounts can prevent diabetes, lower blood pressure, and restore insulin sensitivity. Historically, athletes getting sunlamp exposure have experienced improvements in strength, speed, and endurance. Taking vitamin D while dieting may lead to faster fat loss, particularly in the abdominal area.

  • Optimal muscle function
  • Reduces inflammation
  • Increases muscle protein synthesis



Calcium is especially important for athletes because they are more likely to lose calcium, as well as other minerals, through perspiration. In addition to being important for strong bones, calcium is required for muscle contraction. Without enough calcium you may experience muscle cramps.

  • Prevents muscle cramps
  • Improves bone strength



MCTs can increase fat oxidation, increase energy expenditure, and improve athletic performance. MCT consumption and MCFA oxidation appears to increase body fat oxidation and satiety compared to LCTs, which may expedite fat loss.

  • Improves endurance
  • Increases metabolic rate
  • Promotes fat burning
  • Maintains muscle mass

The Power

Recovery is more than just a buzzword. It is a recognized stage of the muscle building process. The fact is, if you aren’t taking recovery seriously, you are never going to reach your full potential. Recovery is so important that several of the leading sports organizations in the world have created panels of specialists to make sure their million dollar athletes are recovering properly and adequately, and Athlean-Rx ReconstruXion has been a part of that conversation.

The Science

6g of Leucine, a whopping 10g of Glutamine, 1.25g of Betaine… These are just the kick off points for this powerhouse of a formula. As always, we put the science in everything we do, and each and every ingredient is thoroughly researched and backed by studies to prove its efficacy as a sports recovery supplement.

The Facts

You asked and we answered with our most potent formulas and open labels so you know exactly which ingredients and how much of each you’re getting. Athlean-Rx contains no proprietary blends, and as always, no fillers, no substitutes and no harmful chemicals.

The Results

ReconstruXion is the go to recovery formula for some of the top teams in pro sports. It’s been so effective with our athletes that we have several reports of it preventing delayed onset muscle soreness (DOMS) after particularly intense workouts. While these reports are anecdotal at this stage I can personally attest to RX3’s effectiveness in helping me battle DOMS.

I use ReconstruXion daily as a recovery aid and to assist in blunting the effects of DOMS after training.

ATHLEAN RX-3 ReconstruXion


ATHLEAN ReconstruXion CONTAINS: 2g


Research suggestions that L-Carnitine L-Tartrate improves muscle recovery and repair times. This is probably due to a boost in nitric oxide (NO) production, which improves blood flow and oxygen consumption in the muscles. LCLT also increases androgen receptors in the muscle cells, which means more testosterone is recruited to build muscle.

  • Improves muscle recovery and repair between training sessions (probably due to a boost in Nitric Oxide and an increase in muscle oxygen consumption)
  • Increases androgen receptors in muscle cells, thereby recruiting more testosterone to build muscle
  • Improves insulin sensitivity



ATHLEAN ReconstruXion CONTAINS: 6g


Considered one of the most anabolic of all the individual amino acids, L-Leucine is considered to be the main activator of protein synthesis via its effects on the mTOR pathway. What makes it especially vital (and often in deficient supply) is that it is an essential amino acid, which means that the body doesn’t produce it naturally. The only way for you to get this key amino acid in your system is through diet and or supplementation. Throw in its additional researched ability to prevent the breakdown of muscle tissue after intense training, and your ability to tip the balance of muscle growth in your favor just grew by leaps and bounds with ReconstruXion.

  • Reduces muscle breakdown caused by intense exercise or dieting
  • Stimulates protein synthesis, which increases the effectiveness of training and speeds recovery time between training sessions
  • May increase metabolic rate



ATHLEAN ReconstruXion CONTAINS: 10g


L-Glutamine is most commonly used for improving healing time following injuries or surgery. It can help speed recovery time between training sessions due to an increase in nitrogen levels in the muscle cells which assists in protein synthesis. L-Glutamine is also recognized for boosting the immune system, increasing energy levels and helping to regulate blood sugar levels.

  • Reduces healing time after injuries or surgery
  • Increases nitrogen levels in the muscle cells to assist in protein synthesis, which increases the effectiveness of training and speeds recovery time between training sessions
  • Boosts the immune system, which can be compromised by intense training
  • Increases energy levels and helps maintain steady blood sugar levels



ATHLEAN ReconstruXion CONTAINS: 1250mg


One of the most important benefits of Betaine is its ability to improve muscle strength and power during training sessions. Some studies have shown that it can improve endurance, increase the number of reps that can be done with a given weight, and improve power and force with every rep. Evidence also indicates that Betaine improves protein synthesis following training sessions.

  • Improves muscle strength, power and endurance
  • Increases protein synthesis following training sessions
  • Increases growth hormone and insulin-like growth factor 1 production
  • May help promote fat loss



ATHLEAN ReconstruXion CONTAINS: 200mg


L-Theanine is recognized for improving cognitive and mental processing, as well as focus, attention, memory, alertness and mood. It can also help improve sleep quality, reduce stress and help keep the body in a state of relaxation. It also helps improve immune system function, which can become compromised with heavy training.

  • Reduces the effects of stress
  • Increases serotonin and dopamine
  • Improves sleep quality
  • Improves focus, attention, memory, alertness and mood
  • Improves immune system function
  • The most effective dose for Theanine is from 100-250g per day
