Thermogenic Pre-Workout | Legion Pulse+ Burn

Q: How do I use Pulse+ Burn?

Mix 2 scoops with 10–12 ounces of water and take 15–30 minutes before exercise.

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

Pulse+ Burn contains most of the performance-enhancing ingredients found in our original Pulse pre-workout—like caffeine, theanine, citrulline malate, beta-alanine, and betaine—plus three proven fat-burning ingredients: L-carnitine L-tartrate, Capsimax™, and grains of paradise. It’s ideal for people who want the performance boost of Pulse, but with additional ingredients to support fat burning.

Q: How does Pulse+ Burn compare to other popular thermogenic pre-workouts?

Most fat burner pre-workouts either focus too much on boosting energy and focus but neglect fat burning, or the other way around. Many also underdose key ingredients and contain compounds with little scientific support. In contrast, Pulse+ Burn contains the ideal balance of research-backed ingredients at clinically effective doses to support fat burning and boost energy, focus, and athletic performance—without the anxiety, stomach upset, or post-workout crash common with other fat-burning pre-workouts.

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

Pulse+ Burn 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. Take Legion Pulse+ Burn 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 stamina. In other words, whatever type of exercise you do, Pulse+ Burn helps you do it better, while also increasing fat burning.

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

Pulse+ Burn 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 cutting pre-workout supplements) works perfectly. Bottles last longer this way too!

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

You can take Pulse+ Burn on rest days, but there’s little reason to. It’s designed to enhance workout performance and fat burning during exercise, so it’s best taken 15–30 minutes before training. It would give you an energy boost, but it would also mean you couldn’t have much other caffeine—which might be a problem if you enjoy coffee, energy drinks, or other caffeinated beverages.

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

If Pulse+ Burn is too sweet or 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!

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

We recommend you take only one serving of Pulse+ Burn 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: Does Pulse+ Burn have any side effects?

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.

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

On the performance side, you’ll feel an increase in energy, focus, and endurance within 15–30 minutes of taking Pulse+ Burn, thanks to ingredients like caffeine, L-theanine, and betaine. Beta-alanine works a little differently—it gradually raises carnosine levels in your muscles, which typically takes several weeks of consistent use to noticeably enhance performance. As for the fat-burning benefits, you may notice your rate of fat loss improving within the first few weeks of using Pulse+ Burn, provided you’re also maintaining a calorie deficit.

Legion Pulse+ Burn Ingredients (16.93 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[9]
Improves focus, drive, and wakefulness[10][11][12]
Increases metabolic rate[13][14][15]
Enhances strength and power[16][17][18][19][20][21][22]
Boosts endurance[23][24][25][26][27]
Improves anaerobic performance[28][29][30][31][32]
Preserves power output during fatiguing workouts[33]

The clinically effective dose of caffeine for enhancing energy, focus, and performance is between 1 and 6 milligrams per kilogram of body weight.[34][35][36]

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 . . .

Reduces the effects of mental stress[37]
Promotes relaxation[38]
Improves mood, memory performance, and attention (when paired with caffeine)[39][40][41][42]

The clinically effective dose of L-theanine when combined with caffeine is between a ratio of 1:1 and 2:1 theanine to caffeine.

L-Carnitine L-Tartrate (2 grams per serving)

L-carnitine is a naturally occurring amino acid mainly found in meat and dairy. It’s “conditionally essential,” meaning your body can only make it if you’re eating enough lysine and methionine, two amino acids it can’t produce on its own.

L-tartrate is a salt that improves the absorption of other nutrients.

L-carnitine helps your body burn fat more efficiently by shuttling long-chain fatty acids into your cells’ mitochondria, where they’re broken down for energy via a process called β-oxidation.

It also enhances the function of CPT1—the enzyme that controls this process—which may help you burn more fat during exercise, preserve glycogen, and train harder for longer.

Research shows that supplementation with L-carnitine . . .

Supports fat burning[43][44][45]
Reduces exercise-induced muscle damage and soreness[46][47][48][49][50]
May improve strength endurance and power[51]
May enhance antioxidant protection[52][53][54][55]
May increase nitric oxide production[56]

The clinically effective dose of L-carnitine L-tartrate is 500–2000 milligrams per day.

Capsimax™ Capsaicinoid Extract (100 milligrams per serving)

Capsaicinoids are the group of naturally occurring compounds in chili peppers that give the fruit its signature spicy heat.

Capsimax™ is a patented capsaicinoid extract with a controlled-release coating that delivers an effective dose without the digestive discomfort often associated with capsaicin supplements.

Capsaicinoids support fat burning by decreasing the activity of genes that promote fat storage like PPAR-γ and SCD, while activating ones that boost energy expenditure like PGC1α and PRDM16.

Additionally, capsaicinoids activate TRPV1, a protein that responds to heat and supports fat burning and appetite control.

Research shows that supplementation with capsaicinoids . . .

Supports fat burning[57]
Supports appetite control[58]
Increases strength and strength endurance[59][60][61]
Reduces perceived effort during exercise[62][63][64]
May enhance cognitive function[65]

The clinically effective dose of capsaicinoids is 2–10 milligrams per day.

Pulse+ Burn contains 100 milligrams of Capsimax™, which provides 2 milligrams of active capsaicinoids.

Grains of Paradise (30 milligrams per serving)

Grains of Paradise is the common name for the plant Aframomum melegueta, which is an herb in the ginger family that’s commonly used as a spice.

It contains compounds like 6-gingerol and 6-paradol that influence receptors on fat cells involved in energy regulation and temperature perception.

That’s why research shows that supplementation with Grains of Paradise increases energy expenditure and supports visceral fat burning.[66][67][68][69]

The clinically effective dose of Grains of Paradise is around 30 milligrams of an extract providing 3–4 milligrams of 6-paradol.

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.[70][71]

Research shows that supplementation with citrulline malate . . .

Improves muscle endurance[72][73][74][75]
Boosts strength and power[76]
Relieves muscle soreness[77][78]
Reduces perceived effort during exercise[79]

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.[80]

Carnosine reduces muscle acidity, which increases the amount of work that muscles can do before they become fatigued.[81]

Research shows that supplementation with beta-alanine . . .

Improves muscle endurance, particularly during bouts of exercise lasting 1–4 minutes (like circuits or supersets)[82][83][84][85][86]
Improves anaerobic exercise capacity[87][88][89][90][91][92][93]
Reduces feelings of fatigue during exercise[94][95][96]

The clinically effective dose of beta-alanine is between 2.6 and 6.4 grams.

We chose to include 3.6 grams 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.[97]

Betaine (2.5 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[98]
Increases strength and power[99]

The clinically effective dose of betaine is between 2 and 4 grams, with most studies using 2.5 grams.[100][101]

Naturally Sweetened and 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.[102][103][104][105][106][107]

That’s why we use natural sweeteners like stevia, allulose, and monk fruit instead. 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.[108][109][110][111]

No Artificial Food Dyes, Fillers, or Other Unnecessary Junk

As with artificial sweeteners, studies show that artificial food dyes and fillers can cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[112][113][114][115][116]

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.
