10X STIM is not for the faint-hearted. At 24g per scoop, 10X STIM is packed with ingredients backed by good science to help you get the most out of your workout. Most brands will start by telling you what’s NOT included in their pre-workouts, but we’ll be different and start by telling you what’s NOT included in 10X STIM.
At 10X Athletic we do not use:
Illegal and potentially unsafe stimulants. It’s just not how we roll. We are proud to nurture athletes of all levels, including Olympic and professional athletes. So illegal or unsafe stimulants just don’t do it with us.
Prohibited ingredients on the WADA list. Enough said.
Proprietary mixtures. All our labels are completely transparent, so you know exactly what you’re getting in each scoop. No ugly. No surprises.
Bad science. Specifically, we avoid using ingredients with poor science to support their effectiveness. Lots of pre-workouts are filled with cheap ingredients or ingredients with little or no science to support their claims. We do not.
Taurine. Did you know that some brands add Taurine to their caffeinated pre-workouts, and it actually makes their pre-workouts WORSE. Crazy, right? Did you know that 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. Did you know that a combination of caffeine and taurine has NO noticeable effect on your cardiorespiratory fitness, strength, power, or cognitive abilities? If anything, it can have a detrimental effect on the pre-workout you consume. A 2017 study noted that the combination of taurine and caffeine actually INCREASED feelings of fatigue. It seems that adding taurine to caffeinated pre-workouts is not a smart choice for the informed trainer looking for that pre-workout boost.
So, what is included in 10X 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 (NO) nitric oxide boosting ingredient and has been shown to be a more bioavailable and effective nutrient in boosting plasma levels of arginine than L-arginine supplementation alone. Before we go any further, let’s put the debate about l-citrulline v citrulline malate on the bed once and for all. There is only one winner when you want to maximize high-intensity training and anaerobic performance. Unlike l-citrulline, studies have shown that when subjects consumed 8000mg of citrulline malate, they improved their performance during chest and leg strength training, increased repetitions, and reduced their perceived exertion compared to taking a placebo. Additionally, subjects experienced as much as a 40% reduction in muscle soreness compared to subjects who did not consume 8000 mg of citrulline malate. Citrulline can also help your performance at the gym by reducing lactic acid accumulation in your muscles, as it plays an important role in ammonia buffer.
3200mg Beta Alanine Supplementation with Beta Alanine has been shown to raise carnosine levels in skeletal muscle tissue by up to 80%. This improves the muscles’ capacity to buffer hydrogen ions and offsets the “combustion” experienced during intense exercise. Beta Alanine is an incredibly well-researched ingredient, and studies have shown that 3200mg Beta Alanine supplementation can help reduce fatigue and significantly increase endurance. So what does all this mean? Simply put, supplementation with Beta-alanine can provide higher repetitions and superior performance in the gym. You may be wondering if the goal is to raise carnosine, why not supplement directly with carnosine instead? Studies have shown that beta-alanine supplementation is more effective at increasing carnosine levels than supplementing with carnosine alone. Beta-alanine is more bioavailable than carnosine, so it’s more effective at raising carnosine levels in your muscles. If you are not used to supplementing with beta-alanine, pay attention to the “tingling” (paresthesia) sensation. Start with a lower dose and build up your tolerance.
3000mg creatine monohydrate Possibly the most thoroughly researched and effective ingredient in sports nutrition. Creatine monohydrate is not only widely studied, but it also has a wealth of evidence to support its effectiveness. Creatine is an osmolyte that improves cellular hydration and ATP regeneration in your muscle cells. During exercise, ATP is broken down to produce energy. Creatine supplementation increases phosphocreatine stores, which means there is more ATP energy to nourish muscles during high-intensity exercise. In addition to helping your muscle cells produce more energy, studies have shown that supplementation with creatine monohydrate can lead to an increase in strength, muscle mass, muscle endurance and help recover, among other benefits. Creatine monohydrate is the gold standard and is a must for any serious trainer. Creatine, like Beta Alaine is a saturation product, and it does not require a loading phase. However, it is not uncommon for trainers to consume 3-5 g of creatine before and after exercise.
Caffeine 450mg In short, caffeine is the king of (safe) stimulants and is the main energy-boosting ingredient in most pre-workout workouts. Research into caffeine’s physiological effects on physical and mental performance is very extensive. Caffeine levels in your body peak about 45-60 minutes after ingestion and can remain high for 3-4 hours before starting to drop, so it’s not advisable to take caffeinated pre-workouts late in the day. Caffeine counteracts adenosine and GABA receptors (neurotransmitters that induce feelings of fatigue and lethargy). By preventing the binding of these neurotransmitters to their partner receptors, caffeine has been shown to increase mental energy, focus, and motivation, as well as to increase feelings of alertness and improve reaction times. A recent study found that 4.45mg/kg or about 400mg of caffeine increases endurance in athletes and helps burn more calories. Studies have shown that combining taurine with caffeine can have a negative effect on the cardiovascular system and can increase feelings of fatigue. Put simply, 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 ATP turnover rate can limit high-intensity performance. In clinical studies, Peak ATP has been shown to increase muscle power, improve blood flow, increase the number of repetitions, increase lean body mass and reduce fatigue compared to placebo. Based on research, the recommended dose of Peak ATP is 400mg, the exact amount in your 10X pre-workout. Ideally, it should be taken (in your pre-workout) 30-60 minutes before exercise.
2500mg Betaine Anhydrous Betaine is a highly researched, safe and highly effective performance enhancing supplement. Betaine is a natural osmolyte like creatine and promotes cell hydration. It also synergises with creatine to improve the biosynthesis of creatine in the human body. As an osmolyte, betaine improves intracellular water, which promotes muscle volume and muscle swelling. Research has shown that muscle swelling stimulates muscle protein synthesis and decreases protein breakdown, ultimately leading to increased muscle size. Studies have shown that 2500 mg of betaine supplementation can significantly increase anaerobic power, muscle protein synthesis, and weight gain in athletes.
1000mg L-Tyrosine Research has shown that supplementation with tyrosine can increase levels of the neurotransmitters adrenaline, norepinephrine and dopamine. These are important brain chemicals that affect alertness, mood, and your stress response. L-tyrosine is a dopamine precursor, a chemical that regulates the ‘reward and pleasure’ centers in your brain. Since reduced levels of dopamine decrease motivation and performance, increased dopamine levels can have the effect of boosting brain function, mood, and performance under certain conditions.
1000mg Beet Root Extract Beetroot extract is another powerful (NO) nitric oxide boosting ingredient. The nitrates found in beetroot juice and supplements have been shown to increase the excretion of nitric oxide. Human studies suggest that boosting NO can improve muscle pumps and performance during high-intensity interval training and prolonged aerobic exercise.
700mg electrolytes Electrolytes are minerals that become electrically charged when dissolved in fluid and are essential for many important bodily functions. Like many other compounds in the human body, electrolytes must remain within a certain range for proper health and function. During intense exercise, the body loses electrolytes and water by sweating. Depletion of electrolytes can lead to decreased performance, fatigue, cramps, and increase 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, which help support muscle contractions, nerve impulse conduction, regulate heart rate and fluid balance in the body, among many other benefits.
B vitamins incl. 800ug Folic acid Folic acid is a highly bioavailable form of vitamin B9. It plays an important supporting 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) can improve mood, reduce symptoms of depression and improve brain health. Vitamin B12 (methylcobalatim) is an essential vitamin that your body cannot produce. Supplementing with B12 can help support nerve cells’ normal function, energy production, and even help minimize the risk of 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 to improve nutrient absorption and absorption through its active component piperine. Piperine is also an anti-inflammatory, high-level antioxidant and a dopamine maximizer in the body (by stimulating the TRPV receptor in the brain). 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 uptake and nutrient uptake, this can help you get more out of your pre-workout.
