Legion Stim-Free Pulse Ingredients (14.4 grams per serving)
Citrulline Malate (8 grams per serving)
Citrulline malate is a combination of the amino acid L-citrulline and malic acid, a naturally occurring compound found in many fruits that plays a vital role in cellular energy production.
Once ingested, L-citrulline converts into L-arginine in the body, which stimulates the production of nitric oxide — a compound that widens blood vessels, enhances circulation, and improves blood flow.
Research shows that citrulline malate supplementation may:
- Boost muscle endurance, allowing you to train harder and longer
- Reduce muscle soreness, supporting faster recovery after exercise
- Enhance aerobic performance, improving stamina and overall physical output
For optimal results, the clinically effective dosage of citrulline malate ranges between 4 g and 10 g per day, depending on individual needs and training intensity.
Beta-Alanine (3.6 grams per serving)
Beta-alanine is a naturally occurring amino acid that helps regulate the amount of carnosine stored in your muscles.
Carnosine plays a crucial role in reducing muscle acidity, which allows your muscles to perform more work before fatigue sets in. This makes beta-alanine one of the most effective ingredients for boosting endurance, power, and performance.
Research shows that beta-alanine supplementation may:
- Reduce exercise-induced fatigue, helping you train longer and harder
- Improve anaerobic exercise capacity, enhancing performance in high-intensity workouts
- Increase potential workload, which can lead to greater gains in lean muscle mass
- Lower perceived fatigue during training, making workouts feel easier
The clinically effective dosage of beta-alanine ranges between 2.6 g and 6.4 g per day for optimal performance benefits.
In Pulse, we’ve included 3.6 g of beta-alanine per serving — a strategically chosen dose that:
- Delivers significant performance-enhancing benefits
- Minimizes the common, harmless side effect of mild skin prickling, itching, or tingling (known as paresthesia)
- Provides an ideal balance between effectiveness and comfort
Alpha-GPC (300 milligrams per serving)
Alpha-glycerophosphocholine — commonly known as alpha-GPC — is a powerful compound made up of two essential molecules: choline and glycerophosphate.
- Choline is a vital nutrient for brain health, memory, and cognitive performance.
- Glycerophosphate helps transport choline into the brain, supporting optimal neural function.
Once ingested, alpha-GPC boosts the production of acetylcholine, a key neurotransmitter that allows nerve cells to communicate efficiently, while also providing glycerophosphate, which further supports brain structure and function.
Research shows that alpha-GPC supplementation may:
- Increase power output, enhancing athletic performance
- Support long-term cognitive health and reduce age-related decline
- Elevate growth hormone levels, aiding recovery and muscle development
The clinically effective dosage of alpha-GPC ranges between 150 mg and 1,200 mg per day, with 250 mg to 500 mg being ideal for cognitive benefits.
In our stim-free Pulse formula, we’ve included 300 mg of alpha-GPC (50%) per serving — a carefully chosen dose that:
- Delivers proven cognitive and performance benefits
- Optimizes formula balance by allowing us to invest in other high-impact ingredients
- Minimizes the likelihood of headaches, particularly for individuals using stim-free Pulse and Forge together — and especially those combining stim-free Pulse, Forge, and Ascend for enhanced performance
Betaine (2.5 grams per serving)
Betaine — also known as trimethylglycine — is a naturally occurring amino acid found in nutrient-rich foods like beets, spinach, and quinoa.
Betaine is packed with methyl groups, special molecules that play a critical role in several essential physiological functions, including:
- DNA production and cellular repair
- Fat metabolism and energy utilization
- Cellular energy production to fuel performance and recovery
Additionally, betaine acts as an osmolyte — a compound that helps maintain fluid balance inside and outside your cells, supporting hydration, endurance, and muscle performance.
Because of these unique properties, research shows that betaine supplementation may:
- Boost muscle endurance, helping you train harder for longer periods
- Increase strength and power output, improving overall athletic performance
For optimal results, the clinically effective dosage of betaine ranges between 1.25 g and 2.5 g per day, depending on your training intensity and performance goals.
Naturally Sweetened and Flavored
While artificial sweeteners may not be as harmful as some believe, research suggests that regular consumption of these chemicals may negatively impact overall health.
That’s why we choose cleaner, healthier alternatives — using only natural sweeteners like stevia, erythritol, and monk fruit. These plant-based ingredients are not only safe and well-researched, but studies show they may also offer several added health benefits, including:
- Improved nutrient absorption
- Healthier cholesterol levels
- Reduced inflammation
- Better metabolic support and overall wellness
By focusing on natural, science-backed ingredients, we deliver products that are safer, healthier, and better for your body — without compromising on taste or quality.
No Artificial Food Dyes, Fillers, or Other Unnecessary Junk
Just like artificial sweeteners, research shows that artificial food dyes and fillers can cause negative effects in some individuals, including gastrointestinal toxicity and behavioral disturbances.
That’s why we prioritize clean, natural ingredients by using:
- Natural colorings and flavorings sourced from fruits and other plant-based foods
- Naturally derived ingredients that improve texture and maintain product quality
- Safe, high-quality components that enhance shelf life and streamline manufacturing — without compromising purity or performance
The result? Cleaner, safer, and better-tasting products you can trust.
