10X Athletic Stim

10X Athletic STIM is not for the faint hearted. At 24g per scoop 10X Stim is packed with energy boosting ingredients.

At 10X Athletic we don’t use:

Illegal & potentially unsafe stimulants. It’s just not how we roll. We pride ourselves on fuelling athletes of all abilities including Olympic and professional athletes. So, illegal or unsafe stimulants just don’t cut it with us.

Banned ingredients on WADA list. Enough said.

Proprietary blends. All our labels are fully transparent so you know exactly what you’re getting in every scoop. No nasties. No surprises.

Bad Science. Specifically we avoid using ingredients with poor science to back up their efficacy.

Taurine. Did you know some brands add Taurine to their caffeinated pre-workouts and it actually makes their pre-workouts WORSE. Crazy, right? Did you know taurine and caffeine have opposite effects on your central nervous system? Caffeine is a powerful stimulant whereas taurine is an agonist for the inhibitory gamma aminobutyric acid (GABA) receptors. Therefore combining caffeine and taurine has NO tangible effect on your cardiorespiratory fitness, strength, power or cognitive ability.

Ingredients in 10X Athletic STIM:

8000mg Citrulline Malate: 2:1

Looking for better performance, recovery, energy and more powerful pumps? Then citrulline is a ‘must’ in your pre-workout. Citrulline is a powerful Nitric Oxide boosting ingredient and has been found to be a bioavailable and effective nutrient for boosting plasma levels of arginine.

Studies have shown when subjects consumed 8000mg of citrulline malate they improved their performances during chest and leg resistance training exercises, increased repetitions & reduced their perceived exertion vs consuming a placebo. Additionally, subjects experienced as much as a 40% reduction in muscle soreness when compared to subjects that didn’t consume 8000mg of citrulline malate. Citrulline may also help your performance in the gym by reducing lactic acid accumulation in your muscles as it plays an important role in ammonia buffering.

3200mg Beta Alanine:

Supplementing with Beta Alanine has been shown to elevate carnosine levels in skeletal muscle tissue by up to 80%. This improves a muscles capacity to buffer hydrogen ions and offsets “the burn” sensation one experiences during intense exercise. Beta Alanine is an incredibly well researched ingredient and studies have shown 3200mg of Beta Alanine supplementation can help reduce fatigue and significantly increase endurance.

3000mg Creatine Monohydrate:

Quite possibly the most thoroughly researched and effective ingredient in sports nutrition. Creatine monohydrate has a ton of evidence to support its efficacy. Creatine supplementation increases phosphocreatine stores which means there is more ATP energy to fuel muscles during high-intensity exercise. As well as helping your muscle cells produce more energy, studies have shown supplementing with creatine monohydrate may lead to an increase in strength, muscle mass, muscle endurance and help aid recovery amongst other benefits.

Caffeine Anhydrous 450mg:

Simply speaking caffeine is the king of (safe) stimulants and is the main energy boosting ingredient in most pre-workouts. Research into the physiological effects of caffeine on physical and mental performance are very extensive. Caffeine levels in your body peak approx. 45-60 minutes after ingestion and can remain high for 3-4 hours before they begin to drop so it’s not advisable to take caffeinated pre-workouts late in the day. Caffeine antagonises adenosine and GABA receptors (neurotransmitters that induce the feeling of tiredness and lethargy). Caffeine has been shown to increase mental energy, focus and motivation. As well as this it has been shown to enhance the feeling of alertness and improve reaction times.

A recent study found that 4.45mg/kg or approx. 400mg of caffeine increased endurance in athletes and help burn more calories. Studies have shown combining taurine with caffeine can have an adverse effect on the cardiovascular system and can increase the feeling of fatigue. Simply put, avoid combining caffeine and taurine in your pre-workouts.

400mg Peak ATP:

Peak ATP is a patented form of Adenosine 5’-Triphosphate (ATP) Disodium. Peak ATP is identical in structure to the ATP produced and used in the human body. All living cells use ATP for energy. During exercise the demand for ATP increases massively and the rate of ATP turnover can limit high-intensity performance. Based on research the recommended dose of Peak ATP is 400mg, the exact amount in your 10X pre-workout.

2500mg Betaine Anhydrous:

Betaine is a heavily researched, safe and highly effective performance boosting supplement. Betaine is a natural osmolyte like creatine and promotes cell hydration. It also synergises with creatine to enhance the biosynthesis of creatine in the human body. As an osmolyte betaine enhances intracellular water which encourages muscle volumizing and muscle swelling.

Studies have shown 2500mg of Betaine supplementation may significantly increase anaerobic power, muscle protein synthesis and lean mass gains in athletes.

1000mg L-Tyrosine:

Research has shown supplementing with tyrosine may increase levels of the neurotransmitters adrenaline, norepinephrine and dopamine. These are important brain chemicals which affect alertness, mood and your stress response. L-tyrosine is a dopamine precursor, a chemical that regulates the ‘reward and pleasure’ centres in your brain. Since reduced levels of dopamine decrease motivation and performance, increasing dopamine levels may have the effect of boosting brain function, mood and performance under certain conditions.

1000mg Beetroot Extract:

Beetroot extract is another powerful (NO) Nitric Oxide boosting ingredient. Human studies suggest that boosting NO may improve muscle pumps and performance in high intensity interval training and prolonged aerobic training.

700mg Electrolytes:

Electrolytes are minerals that get electrically charged when dissolved in liquid and are essential for many important body functions. During intense exercise the body loses electrolytes and water through sweating. Depletion of electrolytes can lead to performance decline, fatigue, cramping as well as increasing the risk of injury. So we added Potassium, Magnesium and Sodium to our pre-workout to replenish these vital minerals. These are 3 of the most common electrolytes that help support fluid balance in the body amongst many other benefits.

Research has shown supplementing with potassium and magnesium promotes vasodilation by increasing (NO) Nitric Oxide and prostacyclin. This leads to improved blood flow and lower blood pressure.

B Vitamins inc 800ug Folic Acid:

Folic Acid is a highly bioavailable form of vitamin B9. It plays an important support role in the production of dopamine and nitric oxide. B3 (niacin) plays an important role in energy metabolism and cell health. B6 (pyridoxal 5’-phosphate) may improve mood, reduce symptoms of depression & improve brain health. Vitamin B12 (methylcobalatim) is an essential vitamin your body can’t produce. Supplementing with B12 may help support the normal function of nerve cells, energy production and even help to minimize risk for cardiovascular disease. B12 also serves as an important cofactor in the production of dopamine.

20mg Bioperine and AstraGin:

Bioperine is a patented black pepper fruit extract used in pre-workout supplements in order to enhance nutrient uptake and absorption through its active component piperine. Piperine is also a high-level anti-inflammatory, anti-oxidant as well as dopamine maximiser in the body. AstraGin is a patented, 100% plant-derived compound that also increases the absorption of many vital nutrients. Bioperine and AstraGin work synergistically to increase nutrient absorption and therefore help you get more from your pre-workout.
