Ingredients (15.1 grams per serving)
Caffeine (350 milligrams per serving)
Many of us can’t shake the cobwebs without our morning cup of coffee, but this powerful compound is a lot more than a mere pick-me-up.
Caffeine also boosts metabolism, improves strength, promotes muscle endurance, and enhances anaerobic performance.[1][2][3]
The clinically effective dose of caffeine for enhancing performance is between 3 and 6 milligrams per kilogram of body weight.[4]

L-Theanine (350 milligrams per serving)
L-theanine is an amino acid found primarily in tea that’s responsible for some of its health benefits.
It helps balance the levels of two chemicals in the brain known as glutamate and GABA, which transmit nerve impulses.
That’s why research shows that supplementation with L-theanine . . .
- Reduces the effects of mental stress[5]
- Increases the production of nitric oxide, which improves blood flow[6]
- When paired with caffeine, improves mood, memory performance, and attention[7][8][9][10]
The clinically effective dose of L-theanine when combined with caffeine is between a ratio of 1:1 and 2:1 theanine to caffeine, but as 2:1 may produce a calming effect, 1:1 is optimal for working out.

Citrulline Malate (8 grams per serving)
Citrulline malate is the amino acid L-citrulline bound with malic acid, a natural 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.[11][12]
This is why research shows that supplementation with citrulline malate . . .
- Improves muscle endurance[13][14][15]
- Relieves muscle soreness[16]
- Improves aerobic performance[17][18]
The clinically effective dose of citrulline malate is between 4 and 10 grams.

CarnoSyn® 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.[19]
Carnosine reduces muscle acidity, which increases the amount of work that muscles can do before they become fatigued.[20]
This is why research shows that supplementation with beta-alanine . . .
- Reduces exercise-induced fatigue[21][22][23][24]
- Improves anaerobic exercise capacity[25][26][27][28][29]
- Increases potential workload, which can lead to an increase in lean mass[30][31]
- Reduces feelings of fatigue during exercise[32][33][34]
The clinically effective dose of beta-alanine is between 2.6 and 6.4 grams.
We chose to include 3.6 grams of CarnoSyn® 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.[35]

AlphaSize® 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[36]
- Mitigates cognitive decline as we age[37]
- Increases growth hormone levels[38]
The clinically effective dose of alpha-GPC is between 150 and 1,200 milligrams, with 250 to 500 milligrams sufficient for cognitive benefits and higher doses required for affecting dementia.[39]
We chose to include 300 milligrams of AlphaSize® 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.[40][41]
The clinically effective dose of betaine is between 1.25 and 2.5 grams.

100% Naturally Sweetened & Flavored

100% 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.[42][43][44][45][46][47]
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 insulin sensitivity, a lower cholesterol profile, improved blood glucose control, potential anti-cancer effects, lower blood pressure and inflammation levels, and more.[48][49][50][51]

If this is your first time using Pulse, 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 Pulse, including 350 milligrams of caffeine, mix 2 scoops into 10-12 ounces of water, and drink it 15-30 minutes prior to exercise.
