Titan Nutrition Stim-Rush Ingredients

Each 10.7g scoop of Stim-Rush delivers a powerful combination of performance enhancers and stimulants, divided into two focused matrices.

Performance RUSH Complex – 4080mg

The Performance RUSH Complex forms the foundation of Stim-Rush’s effectiveness, delivering clinically-backed ingredients that support exercise performance, endurance, and muscle function throughout your training session.

• Betaine Anhydrous – 2500mg

  Titan Nutrition starts out strong on betaine, including the full clinical dose of 2.5g per serving. Also known as trimethylglycine, betaine is a naturally-occurring compound found in foods like spinach, beets, and whole grains that serves dual roles in performance enhancement.

  As an osmolyte, betaine helps maintain cellular hydration during intense exercise, protecting muscle proteins and enzymes against stress-induced denaturation. This helps preserve power output as your workout progresses and may contribute to enhanced exercise performance.^[1]

  More impressively, betaine supports the body’s methylation pathways, potentially enhancing natural creatine synthesis and promoting favorable hormonal responses to training. Research shows betaine supplementation can improve work capacity during high-volume resistance exercise, increase power output, and support body composition changes.^[2]

  The 2.5g dose found in Stim-Rush aligns perfectly with the amount used in studies showing improvements in sprint performance, muscle endurance, and training volume^[1-4] – making it a perfect foundation for a high-energy, performance-focused pre-workout.

• Agmatine Sulfate – 1000mg

  Stim-Rush includes a solid 1,000mg dose of agmatine sulfate, securing its position as one of the most versatile ingredients in modern pre-workouts. Agmatine, a naturally occurring metabolite of the amino acid arginine, was first discovered in mammalian brain tissue in 1994 and has since emerged as a powerful neuromodulator with multiple performance-enhancing properties.^[5]

  

  At its core, agmatine functions as a nitric oxide modulator through several mechanisms. Rather than directly causing NO production like arginine or citrulline, agmatine inhibits the enzyme that breaks down arginine (arginase), effectively preserving your body’s natural arginine pool for improved NO production.^[6] This leads to enhanced blood flow, nutrient delivery, and the coveted “pump” effect, albeit more modest than what you’d get from a full-spectrum pump formula.

  A neuro boost with that pump

  What really sets agmatine apart from other pump ingredients is its set of neurological benefits. Unlike most pump agents, agmatine crosses the blood-brain barrier, where it influences multiple neurotransmitter systems including:^[7]

  • Blocking NMDA receptors to modulate glutamate activity
  • Interacting with imidazoline receptors to enhance mood and focus
  • Inhibiting certain nitric oxide synthase enzymes that could otherwise lead to oxidative stress
  • Potentially increasing intracellular cAMP levels, which may improve metabolic function

  These neural mechanisms contribute to improved focus, enhanced mind-muscle connection, and even reduced perception of pain during intense training sessions.^[8]

  In addition to its cognitive and pump benefits, research suggests agmatine may help protect neurons from damage during periods of stress.^[9] This neuroprotective effect could potentially aid in recovery following particularly grueling training sessions.

  The 1,000mg dose in Stim-Rush hits the sweet spot for practical benefits without overshooting into territory where diminishing returns occur. While some pump-specific products push higher into the 1.5-2g range, the 1g dose found here works perfectly alongside the Performance RUSH complex’s other ingredients to support reliable blood flow enhancement while delivering noticeable cognitive benefits.^[10]

• Taurine – 500mg

  

  Taurine can induce the browning of fat,^[11] which is important because brown fat is more mitochondrial-dense and metabolically active!

  Taurine remains one of the industry’s most underrated amino acids, functioning as more than just an everyday osmolyte. At 500mg per serving, Stim-Rush delivers a modest but functional dose that complements its stimulant-heavy formula.

  As a conditionally essential amino acid, taurine helps maintain proper cell hydration and volume regulation, potentially reducing muscle cramping during intense training sessions.^[12]

  Where taurine truly shines in this formula is its ability to smooth out the stimulant matrix. Research suggests taurine can reduce jitteriness often associated with caffeine while promoting better blood flow through its vasodilatory properties.^[13]

  Though the 500mg dose falls below the 1-6g range typically used in performance-focused studies, it provides sufficient support when combined with the other performance enhancers in Stim-Rush.^[14] For athletes seeking maximum endurance benefits, additional taurine supplementation could be considered, but this amount effectively serves its purpose as a supportive ingredient in this energy-focused formula.

• Senactiv (Panax notoginseng (root), Rosa roxburghii (fruit)) – 25mg

  Senactiv represents an innovative addition to modern pre-workouts. This patented^[15] combination of Panax notoginseng root and Rosa roxburghii fruit works as a senolytic agent – helping to clear out old, damaged cells in muscle tissue while promoting the growth of new cells.^[16]

  At its core, Senactiv works by enhancing the body’s natural process of removing aging (senescent) cells from exercised muscle, primarily through the action of ginsenoside Rg1 – a key bioactive compound in Panax notoginseng. This cellular clearance creates space for healthier, more functional cells to develop and thrive.^[17]

  Research demonstrates that Senactiv supplementation can significantly boost aerobic performance while accelerating post-exercise glycogen replenishment by up to 2.7 times compared to placebo.^[18]

  

  The 25mg dose in Stim-Rush is exactly in line with the research-backed amount shown to enhance endurance, reduce perceived exertion during training, and promote faster recovery between sessions – making it an intelligent addition to this performance-focused formula.^[16]

• Bioperine (Piper nigrum)(fruit) – 5mg

  BioPerine is a patented^[19-22] black pepper extract standardized to 95% piperine, included at an effective 5mg dose to enhance overall formula bioavailability. This natural compound has been shown to inhibit enzymes that metabolize many nutrients and increase thermogenic activity, potentially improving absorption of Stim-Rush’s other ingredients by up to 30-40% (and a whopping 2000% in the case of curcumin, which we don’t have here though).^[23]

  Beyond absorption enhancement, piperine delivers several independent benefits relevant to training. Research indicates it may help regulate fat metabolism in obesity models,^[24] reduce oxidative stress,^[25] and potentially enhance carbohydrate metabolism during exercise.^[26]

  Though seemingly modest at 5mg, this is actually the go-to dose we see in pre-workouts, and BioPerine represents an intelligent addition that amplifies Stim-Rush’s overall effectiveness.

But now it’s for the fun part — time to get stimmed up:

Cognitive STIM Complex – 873mg

The Cognitive STIM Complex is where Stim-Rush truly shines, delivering a powerful blend of energy and focus-enhancing ingredients that will keep you locked in throughout your most grueling workouts. This carefully formulated blend combines traditional stimulants with cognitive enhancers for a well-rounded energy experience.

• Caffeine Anhydrous – 333mg

  

  At the heart of Stim-Rush sits a substantial 333mg dose of caffeine anhydrous – a dehydrated form of caffeine that provides rapid absorption and maximum potency. This dose delivers serious energy without crossing into excessive territory, perfect for experienced gym-goers seeking sustained intensity.

  Caffeine works primarily by blocking adenosine receptors in the brain, preventing the onset of fatigue while increasing alertness and focus.^[27] Beyond its mental effects, caffeine has been consistently shown to enhance multiple aspects of exercise performance, including power output, endurance, and strength.^[28]

  Research indicates caffeine can boost fat metabolism during exercise, potentially enhancing fat-burning effects of your training.^[29]

  This substantial caffeine dose works synergistically with other stimulants in the formula, creating a comprehensive energy profile that builds quickly and sustains throughout your workout without the dreaded crash.

  For those who aren’t ready for 333mg caffeine, you may need to use a ½ to ¾ scoop to assess tolerance!

• Alpha-GPC 50% (L-Alpha Glycerylphosphorylcholine) – 300mg

  

  Titan Nutrition includes Alpha-GPC in Stim-Rush to boost cognitive function and enhance the mind-muscle connection during training. This 300mg dose (yielding 150mg of actual Alpha-GPC at 50% concentration) works synergistically with caffeine to create a comprehensive cognitive enhancement effect.

  Alpha-GPC is a choline-containing phospholipid that readily crosses the blood-brain barrier, serving as a precursor to acetylcholine – a neurotransmitter crucial for muscle contraction, memory formation, and cognitive function.^[30]

  Research indicates that Alpha-GPC supplementation can significantly increase motivation levels in healthy individuals, which aligns perfectly with Stim-Rush’s focus on driving intense training sessions.^[31]

  Where Alpha-GPC truly shines is in supporting explosive power output. A 2015 study found that just 6 days of Alpha-GPC supplementation led to significant improvements in lower body force production during isometric testing.^[32] More recent research confirms these findings, with improved cognitive performance and faster reaction times observed after supplementation in resistance-trained men, but those did require a higher dose at a higher standardization.^[33]

  By including Alpha-GPC alongside stimulants like caffeine, Stim-Rush creates a comprehensive cognitive formula that enhances not just mental energy, but also focus, motivation, and potentially physical power output – making it an intelligent addition to this performance-focused pre-workout.

• Dendrobium Extract (Dendrobium nobile Lindl)(stem) – 100mg

  

  Dendrobium adds another dimension to Stim-Rush’s energy matrix, working synergistically with caffeine and synephrine for a comprehensive stimulant effect. This traditional Chinese medicinal herb derived from orchid stems has been used for centuries and contains alkaloids that may enhance energy, focus, and athletic performance.^[34]

  The primary alkaloids in dendrobium, including dendrobine, have shown impressive benefits for metabolic function – potentially increasing glucose transports (GLUT2, GLUT4) and activating pathways associated with lipid metabolism in the liver.^[35]

  Where dendrobium truly shines is its ability to provide smooth, sustained energy without the anxiogenic effects sometimes associated with high-dose stimulant formulas. Research suggests dendrobium alkaloids may upregulate PGC1α (peroxisome proliferator-activated receptor-gamma coactivator), a master regulator of cellular energy metabolism.^[34]

  At 100mg, this extract provides noticeable energy enhancement while complementing the other stimulants in Stim-Rush, contributing to the formula’s balanced, crash-free energy profile.

• L-Theanine – 100mg

  L-Theanine serves as the perfect complement to Stim-Rush’s stimulant profile, included at 100mg to smooth out the energy curve and enhance focus without sedation. This unique amino acid, primarily found in green tea leaves, creates a state often described as “alert relaxation” – maintaining energy while reducing the jittery side effects commonly associated with high-caffeine formulas.^[36]

  

  L-Theanine increases attention and reduces reaction time — especially in stressed individuals!^[37]

  Research shows L-theanine works through multiple pathways, including increasing alpha brain wave activity (associated with relaxed alertness) and modulating key neurotransmitters like GABA, dopamine, and serotonin.^[38]

  When paired with caffeine, as in Stim-Rush, L-theanine creates a synergistic effect that improves attention performance and cognitive function beyond what either compound achieves alone.^[39]

  While the 100mg dose is on the lower end of clinical efficacy (with many studies using 200-400mg), it still provides noticeable smoothing effects when strategically combined with caffeine in the 3:1 caffeine-to-theanine ratio found in Stim-Rush.^[40]

• Synephrine HCl – 40mg

  Synephrine HCl provides a strategic energy boost to complement Stim-Rush’s substantial caffeine content. At 40mg per serving, this thermogenic compound contributes to the formula’s sustained energy delivery without the jitters often associated with higher caffeine doses alone.

  Extracted primarily from bitter orange (Citrus aurantium), p-synephrine has emerged as a popular alternative to ephedrine due to its ability to support fat oxidation and energy expenditure without significant cardiovascular effects.^[41]

  

  Unlike ephedrine, synephrine’s molecular structure (with a hydroxyl group in the para position) significantly alters its receptor binding properties, allowing it to stimulate β-3 adrenoreceptors rather than the α-adrenergic and β-1/β-2 receptors associated with blood pressure and heart rate changes.^[41]

  Research indicates that p-synephrine can increase fat oxidation during exercise by 29-44%, making it particularly valuable in a training supplement.^[42]

  When paired with caffeine, synephrine creates a complementary energy matrix that enhances workout intensity while supporting the body’s natural fat-burning processes – perfect for those looking to maintain energy while managing body composition.

Added Vitamins and Minerals

• Vitamin B12 (as Methylcobalamin) – 100mcg (4167% DV)

  Vitamin B12 serves as a critical nutrient for multiple bodily functions, including red blood cell formation and neurological health. While often promoted as a solution for fatigue and cognitive issues, research shows mixed results. A comprehensive 2021 systematic review found little evidence that B12 supplementation improves cognitive function or depressive symptoms in individuals without neurological disorders.^[43] However, B12 remains essential for proper nerve function and energy metabolism, with deficiency causing serious health complications including anemia, nerve damage, and cognitive decline. The 500mcg dose here provides basic support for everyday wellness.

• Sodium (as Pink Himalayan Salt) – 100mg (4% DV)

  

  Pink himalayan salt is an excellent source of electrolytes. Don’t fear the sodium!! We need it for optimal training!

  Sodium from Pink Himalayan Salt provides essential electrolyte support during intense training sessions. While 100mg represents just 4% of your daily value, this strategic inclusion helps maintain proper fluid balance and supports neural function without overloading sodium intake.^[44] For athletes who sweat heavily, this modest dose helps initiate electrolyte replacement while allowing personalized post-workout sodium intake based on individual needs.^[45] This inclusion reflects Titan’s thoughtful approach to performance support.

Flavors Available

Here’s an up-to-date list of all flavors of Titan Nutrition Stim-Rush:

Titan Nutrition initially launched four refreshing flavor options to their Stim-Rush pre-workout: Sour Gummy, Watermelon Limeade, Cherry Lime, and Strawberry Kiwi. Each flavor provides a clean, enjoyable taste experience without artificial colors – staying true to Titan’s “no BS” philosophy.

These flavor options strike a balance between familiar favorites and unique combinations, ensuring there’s something for everyone. The smaller 10.7g scoop size (compared to KRE-EX Unrivaled’s massive 32g serving) means great mixability and a more concentrated flavor experience that masks the active ingredients effectively.

Titan Nutrition KRE-EX Unrivaled is the ultimate 2-in-1 pre-workout and creatine supplement, combining 5g creatine with 10g citrulline and 375mg caffeine in one powerful scoop. No need for multiple products!

Stacking Options

While Stim-Rush delivers powerful energy and focus on its own, strategic stacking can enhance your results even further:

• Titan Nutrition Creatine – Since Stim-Rush doesn’t include creatine (unlike KRE-EX Unrivaled), adding 5g of Titan’s pure creatine monohydrate is ideal for supporting strength, power output, and muscle fullness. Take 5g daily, regardless of training schedule.
• Titan Nutrition Beta-Alanine – For those pushing through high-rep training or metabolically demanding workouts, adding Titan’s Beta-Alanine will provide the endurance support missing from Stim-Rush. The clinical 3.2g dose helps buffer lactic acid, extending performance during intense training sessions.
• Titan Nutrition Whey – After pushing yourself with Stim-Rush’s energy matrix, maximize recovery with their Whey protein post-workout, with a classic high-leucine amino acid profile to fuel muscle protein synthesis.

For those training days where both maximum pumps and extreme energy are needed, you could even consider a half-scoop of both Stim-Rush and KRE-EX Unrivaled – though this advanced approach should only be attempted by those with high stimulant tolerance due to the combined caffeine content.
