Legion Pulse Ingredients (15.1 grams per serving)
Caffeine (350 milligrams per serving)
Caffeine is a naturally occurring substance found in many plants native to Africa, East Asia, and South America, including various kinds of tea, cocoa, and coffee.
Caffeine’s primary effects in the body are to stimulate the central nervous system and block the activity of another chemical—adenosine—that causes tiredness.
Research shows that supplementation with caffeine . . .
- Boosts mood and energy levels[11]
- Improves focus, drive, and wakefulness[12][13][14]
- Increases metabolic rate[15]
- Enhances strength and power[16][17][18][19][20]
- Boosts endurance[21][22][23]
- Improves anaerobic performance[24][25][26][27][28]
The clinically effective dose of caffeine for enhancing energy, focus, and performance is between 1 and 6 milligrams per kilogram of body weight.[29][30][31]
L-Theanine (350 milligrams per serving)
L-theanine is an amino acid found primarily in tea that helps balance the levels of two chemicals in the brain—glutamate and GABA—that transmit nerve impulses and affect mood, cognitive performance, and more.
Research shows that supplementation with L-theanine . . .
- Reduces the effects of mental stress[32]
- Promotes relaxation[33]
- Improves mood, memory performance, and attention (when paired with caffeine)[34][35][36][37]
- Increases the production of nitric oxide (which improves blood flow)[38]
The clinically effective dose of L-theanine when combined with caffeine is between a ratio of 1:1 and 2:1 theanine to caffeine.
Citrulline Malate (8 grams per serving)
Citrulline malate is the amino acid L-citrulline bound with malic acid, a substance found in many fruits that is involved in the creation of cellular energy.
L-citrulline turns into another amino acid in the body known as L-arginine, which increases the production of a gas known as nitric oxide that widens blood vessels and improves blood flow.[39][40]
This is why research shows that supplementation with citrulline malate . . .
- Improves muscle endurance[41][42][43]
- Relieves muscle soreness[44]
- Improves aerobic performance[45][46]
The clinically effective dose of citrulline malate is between 4 and 10 grams.
Beta-Alanine (3.6 grams per serving)
Beta-alanine is a naturally occurring amino acid that regulates the amount of the molecule carnosine that can be stored in the muscles.[47]
Carnosine reduces muscle acidity, which increases the amount of work that muscles can do before they become fatigued.[48]
This is why research shows that supplementation with beta-alanine . . .
- Reduces exercise-induced fatigue[49][50][51][52]
- Improves anaerobic exercise capacity[53][54][55][56][57]
- Increases potential workload, which can lead to an increase in lean mass[58][59]
- Reduces feelings of fatigue during exercise[60][61][62]
The clinically effective dose of beta-alanine is between 2.6 and 6.4 grams.
We chose to include 3.6 grams of beta-alanine per serving because it provides significant performance benefits while also minimizing the common and harmless side effect of a mild prickling, itching, or tingling of the skin.[63]
Alpha-GPC (300 milligrams per serving)
Alpha-glycerophosphocholine (also known as alpha-GPC and glycerophosphocholine) is a compound that contains two molecules known as choline and glycerophosphate.
Choline is a nutrient that’s vital for brain health and function, and glycerophosphate is a substance that helps transport choline to the brain.
When ingested, alpha-GPC increases the activity of a chemical in the brain known as acetylcholine, which is used by nerves to communicate with each other, and provides the brain with glycerophosphate, which can improve its health and function.
This is why research shows that supplementation with alpha-GPC . . .
- Increases power output[64]
- Mitigates cognitive decline as we age[65]
- Increases growth hormone levels[66]
The clinically effective dose of alpha-GPC is between 150 and 1,200 milligrams, with 250 to 500 milligrams sufficient for cognitive benefits.[67]
We chose to include 300 milligrams of alpha-GPC (50%) per serving because it’s enough to provide some benefit without eating up too much budget that we’d rather spend on other ingredients.
Furthermore, this dose reduces the likelihood of headaches in people who are using Pulse and Forge together, and especially in people who are using Pulse, Forge, and Ascend together.
Betaine (2.5 grams per serving)
Betaine (also known as trimethylglycine) is an amino acid found in various foods like beets (hence the name), spinach, and quinoa.
Betaine’s rich in a special molecule known as a methyl group, which is a vital component of many physiological functions, including DNA production, fat metabolism, cellular energy production, and more.
Betaine’s also an osmolyte, which is a substance that helps balance fluid levels inside and outside cells.
These two properties are beneficial during times of physical stress, and this is why studies show that betaine boosts muscle endurance and increases strength.[68][69]
The clinically effective dose of betaine is between 1.25 and 2.5 grams.
Naturally Sweetened & Flavored
While artificial sweeteners may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health.[70][71][72][73][74][75]
That’s why we use the natural sweeteners stevia and erythritol instead. Studies show that these ingredients are not only safe but can also confer several health benefits, including better nutrient absorption, healthy cholesterol and inflammation levels, and more.[76][77][78][79]
No Artificial Food Dyes or Other Unnecessary Junk
As with artificial sweeteners, artificial food dyes aren’t a hazard per se, but studies show they can cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[80][81][82][83][84]
That’s why we use natural flavoring and coloring derived from fruits, plants and other foods.

Frequently Asked Questions
If this is your first time using Pulse pre-workout, assess your individual tolerance by mixing 1 scoop with 10-12 ounces of water and drinking it 15-30 minutes prior to exercise. If you experience any non-optimum effects, stop and consult your doctor.
If 1 scoop is well tolerated and you want the full clinically effective dose of Legion Pulse, including 350 milligrams of caffeine, mix 2 scoops into 10-12 ounces of water, and drink it 15-30 minutes prior to exercise.
Compared to other popular pre-workouts, Legion’s pre-workout, Pulse, provides a clean rush of energy with no crash or jitters and an optimal dose of performance-enhancing ingredients to make your workouts significantly more enjoyable and productive.
The only stimulant in Pulse pre-workout is a moderate dose of caffeine, and we’ve also included a matching dose of the amino acid theanine, which makes the caffeine rush and “comedown” noticeably smoother and more enjoyable. Other pre-workouts can leave you feeling edgy and burned out.
Pulse pre-workout is good for both anaerobic and aerobic workouts. It’s not just for weightlifting but for cardio and endurance training, too.
Take Legion Pulse before a weightlifting workout to see benefits like increased strength and muscle endurance. Take it before a cardio session and see benefits like increased intensity and endurance. Whatever type of exercise you do, Legion’s Pulse pre-workout helps you do it better.
Pulse is for men and women. Keep in mind that each serving contains 350 milligrams of caffeine, which may be too much for some women (or smaller men). In those cases, ½ of a serving (which contains more active ingredients than a full serving of most other pre-workout supplements) works perfectly. Bottles last longer this way too!
If Legion Pulse is too sweet/strong tasting for you, increase the amount of water you’re using until you find an amount that works for you. (Most people like 8 to 10 ounces.)
Also, we continually tweak Pulse’s flavor profile based on customer feedback, so please let us know if you don’t like it. It helps us improve!
We recommend you take only one serving of Pulse per day. Research shows that caffeine intake shouldn’t exceed 6 milligrams per kg of body weight per day (about 400 milligrams for the average person), and that most of the benefits are seen at moderate (not excessive) doses.
The only side effect that sometimes surprises people is a tingling or itching sensation often felt in the hands and face. This is known as paresthesia, and is a harmless side effect of beta-alanine and isn’t an allergic reaction or cause for concern.
The reason for this phenomenon is that beta alanine happens to trigger certain neurons present in the skin that also produce feelings of itchiness and warmth.
