Pulse+ Pump: Nitric Oxide Pre-Workout Supplement

Q: How quickly will I notice benefits from Pulse+ Pump?

You’ll feel more energy and focus within 15 to 30 minutes of taking Pulse+ Pump, and during your workout, you’ll notice better endurance and stronger pumps, especially during high-rep sets. What’s more, beta-alanine benefits build with consistent use, while nitrates can support performance both acutely and with regular supplementation.

Q: What’s the difference between Pulse+ Pump and Pulse?

Pulse+ Pump contains all of the performance-enhancing ingredients found in our original Pulse pre-workout—like caffeine, theanine, citrulline malate, beta-alanine, alpha-GPC, and betaine—plus three ingredients shown to increase the muscular pump you get from resistance training. It's ideal if you want the balanced performance boost of Pulse, with added support for blood flow, muscular endurance, and cellular swelling.

Q: How does Pulse+ Pump compare to other popular pump pre-workouts?

Most pump pre-workouts suffer from one or more problems: They underdose key ingredients, especially nitrate. They contain compounds with little scientific support, like agmatine, L-arginine, and L-norvaline. They don’t contain caffeine—usually because supplement brands want you to buy their regular caffeinated pre-workout along with their pump pre-workout. In other words, most pump pre-workouts are just weak pre-workout supplements with small doses of pump-enhancing ingredients sprinkled in for marketing purposes. In contrast, Pulse+ Pump contains the ideal balance of research-backed ingredients at clinically effective doses to boost performance, blood flow, and cellular swelling—maximizing performance with a particular emphasis on enhancing the pump you get from resistance training.

Q: What type of workouts is Pulse+ Pump good for?

Pulse+ Pump pre-workout is good for both anaerobic and aerobic workouts. That is, it’s not just for weightlifting but for cardio and endurance training, too. While Pulse+ Pump is primarily designed to improve the pump you get from resistance training, many of the same ingredients, such as nitrate, also support endurance performance. Take Legion Pulse+ Pump before a weightlifting workout to see benefits like increased strength, power, and muscular endurance. Take it before a cardio session and see benefits like increased stamina and resistance to fatigue and reduced feelings of exertion. [1] In other words, whatever type of exercise you do, Pulse+ Pump helps you do it better. 1 https://pubmed.ncbi.nlm.nih.gov/31172827/

Q: Why does Pulse+ Pump make me tingle?

This is known as paresthesia , and it’s a harmless side effect of beta-alanine—not an allergic reaction or cause for concern. It typically manifests as a warm, tingly sensation in the face and hands, and subsides within 10–15 minutes. The reason for this phenomenon is that beta alanine can trigger certain neurons present in the skin that also produce feelings of itchiness and warmth. [1] It also tends to decrease with repeated use. 1 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3491570/

Q: Is Pulse+ Pump pre-workout for men and women?

Pulse+ Pump is for men and women. Keep in mind that each serving contains 350 milligrams of caffeine, which may be too much for some people. In those cases, ½ of a serving (which contains more active ingredients than a full serving of most other pump pre-workout supplements) works perfectly. Bottles last longer this way too!

Q: How many servings of Pulse+ Pump can I take in one day?

We recommend you take only one serving of Pulse+ Pump 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.

Q: Can I take Pulse+ Pump on non-training days?

Yes. While several of the ingredients in Pulse+ Pump work acutely, like caffeine, L-theanine, and citrulline malate, others like arginine nitrate, betaine nitrate, and beta alanine raise your muscular levels of nitrate and carnosine over time.

Q: Is Pulse+ Pump gluten-free, vegetarian, or vegan?

Yes, Pulse+ Pump is gluten-free, vegetarian, and vegan.

Q: Pulse+ Pump is too sweet/strong tasting for me. What should I do?

If Pulse+ Pump 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+ Pump’s flavor profile based on customer feedback, so please let us know if you don’t like it. It helps us improve!

Legion Pulse+ Pump Ingredients (18.7 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[6]
Improves focus, drive, and wakefulness[7][8][9]
Increases metabolic rate[10][11][12]
Enhances strength and power[13][14][15][16][17][18][19]
Boosts endurance[20][21][22][23][24]
Improves anaerobic performance[25][26][27][28][29]
Preserves power output during fatiguing workouts[30]

The clinically effective dose of caffeine for enhancing energy, focus, and performance is between 1 and 6 milligrams per kilogram of body weight.[31][32][33]

L-Theanine (350 milligrams per serving)

L-theanine is an amino acid mainly found in green tea. It supports relaxation and focus by interacting with neurotransmitters like glutamate, GABA, serotonin, and dopamine to lower excitatory brain signals and boost calming ones.

Research shows that supplementation with L-theanine . . .

Improves memory and attention (when paired with caffeine)[34][35][36][37]
Promotes relaxation and calmness[38][39]
Improves mood[40]

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 a compound consisting of L-citrulline—an amino acid found in foods like watermelon, pumpkin, and cucumber—and malic acid, a naturally occurring component of many fruits and vegetables that supports energy production.

The body converts L-citrulline into the amino acid L-arginine, which increases the production of nitric oxide—a gas that widens blood vessels and improves circulation.[41][42]

This is why research shows that supplementation with citrulline malate . . .

Improves muscle endurance[43][44][45][46]
Increases strength and power[47]
Relieves muscle soreness[48][49]
Reduces perceived effort during exercise[50]

The clinically effective dose of citrulline malate is between 6 and 8 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.[51]

Carnosine reduces muscle acidity, which increases the amount of work that muscles can do before they become fatigued.[52]

This is why research shows that supplementation with beta-alanine . . .

Improves muscle endurance, particularly during bouts of exercise lasting 1–4 minutes (like circuits or supersets)[53][54][55][56][57]
Improves anaerobic exercise capacity[58][59][60][61][62][63][64]
Reduces feelings of fatigue during exercise[65][66][67]

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.[68]

Taurine (2 grams per serving)

Taurine is an amino acid found mostly in seafood and meat. It helps protect cells from oxidative stress and supports normal heart and muscle function.[69][70]

It’s also a potent osmolyte, which is a substance that helps balance fluid levels inside and outside cells.[71]

Research shows that supplementation with taurine . . .

Improves muscular endurance and power[72][73]
Supports healthy blood pressure levels during exercise[74][75]
Reduces post-exercise muscle soreness[76][77][78][79]
Supports healthy blood vessel function[80][81]

The clinically effective dose of taurine is between 1 and 6 grams per day, with research showing the majority of benefits come from 1 to 3 grams.

Betaine (2 grams per serving)

Betaine (or trimethylglycine) is a compound derived from the amino acid glycine and found in foods like beets, spinach, and quinoa.

Betaine has three methyl groups—small chemical units containing one carbon and three hydrogen atoms that your body uses in essential processes like building DNA, breaking down fats, and producing energy.

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, which is why studies show that supplementation with betaine . . .

Boosts muscle endurance[82]
Increases strength and power[83]

The clinically effective dose of betaine is between 2 and 4 grams, with most studies using 2.5 grams.[84][85]

NO3-T® Arginine Nitrate (1 gram per serving)

Nitrate is a compound found naturally in leafy greens and beets. Your body converts it first into nitrite and then into nitric oxide, a gas that widens blood vessels, boosts blood flow, and improves muscular efficiency.[86][87][88][89]

A unique feature of nitrate is that it’s “activated” under conditions of fatigue and acidosis, meaning the benefits are strongest when your muscles are working hardest—such as the last few reps of a hard, high-rep set.

Nitrate quickly degrades unless it’s bound to another substance, however, which is why we use NO3-T® Arginine Nitrate, a patented combination of arginine and nitrate that reliably raises nitric oxide levels in your muscles.

Research shows that supplementation with nitrate . . .

Increases muscular blood flow[90][91]
Increases muscular power and stamina[92][93][94][95][96]
Improves both high- and moderate-intensity endurance performance[97][98]

The clinically effective dose of nitrate is 6.4 to 12.9 milligrams per kilogram of body weight, with studies using fixed doses generally supporting 400 milligrams or more.

Each serving of Pulse+ Pump contains 1 gram of NO3-T® Arginine Nitrate, which provides 260 milligrams of nitrate. When combined with the next ingredient, NO3-T® Betaine Nitrate, this provides you with 610 milligrams of total nitrate per serving.

NO3-T® Betaine Nitrate (1 gram per serving)

NO3-T® Betaine Nitrate is a patented combination of betaine and nitrate, which reliably increases nitric oxide levels in your muscles in a manner similar to arginine nitrate.

Research shows that supplementation with nitrate . . .

Increases blood flow to skeletal muscle[99][100]
Increases maximum muscular power[101]
Improves resistance training power and endurance[102][103][104][105]
Improves both high- and moderate-intensity endurance performance[106][107]

The clinically effective dose of nitrate is 6.4 to 12.9 milligrams per kilogram of body weight, with studies using fixed doses generally supporting 400 milligrams or more.

Each serving of Pulse+ Pump contains 1 gram of NO3-T® Betaine Nitrate, which provides 350 milligrams of nitrate along with 650 milligrams of betaine.

Combined with the 260 milligrams of nitrate from NO3-T® Arginine Nitrate, this provides you with 610 milligrams of total nitrate per serving.

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[108][109]
Supports cognitive health and performance[110]
Increases force production[111]

The clinically effective dose of alpha-GPC is between 150 and 1,200 milligrams, with 250 to 500 milligrams sufficient for cognitive benefits.[112]

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+ Pump and Ascend together.

Grape Seed Extract (100 milligrams per serving)

Grape seed extract is a substance derived from the ground-up seeds of red wine grapes, and it has long been used in European medicine.

It contains a powerful antioxidant known as procyanidin B2, which reduces oxidative stress in your circulatory system and raises levels of an enzyme called nitric oxide synthase, which increases blood flow to the muscles and improves the body’s ability to efficiently use oxygen during exercise.[113]

Research shows that supplementation with grape seed extract . . .

Increases blood flow[114][115]
Improves exercise efficiency and endurance[116]
Reduces post-exercise muscle damage[117]

The clinically effective dose of grape seed extract is between 100 and 300 milligrams.

Naturally Sweetened and Flavored

We use natural sweeteners like stevia, allulose, and monk fruit instead as well as natural flavoring and coloring derived from fruits and other foods. Research shows that these ingredients are not only safe but can also confer several health benefits, such as supporting weight management, antioxidant activity, digestive health, and more.[118][119][120][121][122][123]

No Artificial Sweeteners, Flavors, or Fillers

While artificial sweeteners, food dyes, and fillers may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health.[124][125][126][127][128]

That’s why we use natural coloring and flavoring derived from fruits and other foods as well as naturally derived ingredients for improving texture, enhancing shelf life, and facilitating the manufacturing process.
