Ingredients (17.57 grams per serving)

Pulse Pre-Workout

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]

Caffeine

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.

L-Theanine

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 . . .

The clinically effective dose of citrulline malate is between 4 and 10 grams.

Citrulline Malate

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 . . .

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]

CarnoSyn® Beta-Alanine

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.

AlphaSize® Alpha-GPC

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.

Betanine

Energy Surge Energy Supplement

Caffeine Anhydrous (100 milligrams per serving)

Many of us can’t shake the cobwebs without our morning cup of coffee, but this compound is a lot more than a mere pick-me-up.

Caffeine also boosts metabolism, improves strength, promotes muscle endurance, and enhances anaerobic performance.[42][43][44]

The clinically effective dose of caffeine for enhancing performance is between 3 and 6 milligrams per kilogram of body weight.[45]

We included 100 milligrams of caffeine in Energy Surge because it’s enough to provide benefits while also allowing you to safely use a caffeinated pre-workout supplement like Pulse or drink caffeinated beverages like coffee, tea, and energy drinks.

Caffeine

L-Theanine (100 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[46]
  • Increases the production of nitric oxide, which improves blood flow[47]
  • When paired with caffeine, improves mood, memory performance, and attention[48][49][50][51]

The clinically effective dosage 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, the 1:1 ratio we’ve used in Energy Surge is optimal for boosting energy, focus, and athletic performance.

L-Theanine

Taurine (2 grams per serving)

Taurine is an amino acid found primarily in seafood and meat that plays an important role in cardiovascular and muscle function by protecting cells from oxidative stress and regulating the release of neurotransmitters and glucose.[52][53]

Research shows that supplementation with taurine . . .

  • Improves focus, attention, and verbal reasoning when combined with caffeine[54][55]
  • Helps minimize unwanted side effects of caffeine (like jitters)[56]
  • Helps prevent a “sugar crash” by slowing the release of glucose into the blood[57][58]

The clinically effective dose of taurine is 1-to-3 grams.

L-Theanine

Rhodiola Rosea Extract (250 milligrams per serving)

Rhodiola rosea (also known as Golden Root) is a plant that grows in cold parts of the world, including the Arctic regions of Europe, Asia, and North America.

It’s known as an adaptogen, which is a substance that causes an imperceptible level of stress in the body and trains it to better handle future stresses.

Research shows that supplementation with rhodiola rosea . . .

  • Improves mood and reduces symptoms of stress and depression[59][60][61]
  • Reduces stress-related fatigue[62]
  • Preserves and possibly enhances cognition and mood during strenuous periods[63]
  • May enhance physical performance[64]
  • May reduce exercise-induced muscle damage[65]
  • May help the body defend against viral infections[66]

The clinically effective dose of rhodiola rosea is unknown, but most long-term benefits have been observed with 90 to 120 milligrams.

Energy Surge contains 250 milligrams of rhodiola rosea per serving because it may produce quicker results.

Forskolin

B Vitamin Complex (27.4 milligrams per serving)

B vitamins are a category of naturally-occurring substances that cells need to turn food into energy. They also affect mood, feelings of wellness, and brain, nerve, and cardiovascular function.

Research shows that supplementation with B vitamins (particularly vitamins B2, B3, B6, and B12) . . .

  • Reduces stress[67]
  • Improves mental clarity, energy, and focus[68]
  • Boosts cognitive function and memory[69][70]
  • Can prevent and reduce symptoms of depression[71][72]

There is no established clinically effective dose of a B vitamin complex, but the B vitamins thought to most improve energy, mood, and cognitive function are B2, B3, B6, and B12.

Energy Surge contains 3.4 mg of vitamin B2 (as riboflavin), 20 mg of vitamin B3 (as niacin), 4 mg of vitamin B6 (as pyridoxal-5-phosphate), 12 mcg of vitamin B12 (as methylcobalamin).

Fucoxanthin

Performance Surge Performance Supplement

KSM-66 Ashwagandha Extract (600 milligrams per serving)

Ashwagandha root extract is a substance derived from a plant root commonly used in Ayurvedic medicine. It’s known as an adaptogen, which is a compound that causes an imperceivable level of stress in the body that trains it to better handle future stresses.

Research shows that supplementation with ashwagandha root extract . . .

  • Increases power and strength[73]
  • Reduces cortisol levels from stress[74][75]
  • Lowers feelings of stress and anxiety[76][77][78]
  • Helps restore lost fertility in men[79]
  • Improves immune system function[80]
  • Increases cardiovascular endurance[81]
  • Protects against pigments that accumulate during Alzheimer’s disease and is thought to have a therapeutic effect in those with the disease[82][83]

The clinically effective dose of ashwagandha root extract is between 50 and 500 milligrams of the patented KSM-66® brand, with a few instances of over 5,000 milligrams of raw powder being used acutely.

Caffeine

PeakATP® (450 milligrams per serving)

Adenosine triphosphate (ATP) is the most basic form of cellular energy in the body. It’s obtained through the conversion of carbohydrates and fat, and it fuels the myriad functions and processes that sustain life and activity, including metabolism and muscle contraction.

PeakATP® is a form of ATP obtained from the glucose in corn that’s chemically identical to what our body produces and thus is available for immediate use.

Research shows that supplementation with PeakATP® . . .

  • Improves blood flow to muscles during exercise[84]
  • Increases muscular endurance[85][86]
  • Reduces perceived exertion[87]

The clinically effective dose of PeakATP® is 400 milligrams.

Pulse Lab Test Pulse Stim-Free Lab Test Certificate Energy Surge COA Performance Surge COA

How to Use the Pre-Workout Energy & Performance Stack

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 unwanted 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.

As for Energy Surge, you have two options:

  1. Mix 1 serving of Energy Surge (1 scoop) into 10-to-12 ounces of water containing 1 serving of Pulse (2 scoops), and drink it 15-30 minutes prior to exercise. This allows you to enjoy the full benefits of both products, but it requires moderate caffeine tolerance (450 milligrams).
  2. Mix 1 serving of Energy Surge (1 scoop) into 10-to-12 ounces of water containing ½ of a serving of Pulse (1 scoop), and drink it 15-30 minutes prior to exercise. This allows you to benefit from the ingredients in both products while keeping your caffeine intake relatively low (275 milligrams). Remember, however, that Pulse is maximally effective when a full serving is taken.

And as for Performance Surge, mix 1 serving (1 scoop) into 1⁄2-to-1 serving of Pulse (1-to-2 scoops) and 1 serving of Energy Surge (1 scoop), and drink it 15-30 minutes prior to exercise.

Mix 1 serving of Energy Surge (1 scoop), 1 serving of Performance Surge (1 scoop), and 1 serving of Stim-Free Pulse (2 scoops) into 10-12 ounces of water, and drink it 15-30 minutes prior to exercise.
