LEGION PULSE Pre-Workout Supplement

Written by:
LEGION PULSE Pre-Workout Supplement


This is the pre-workout from my line of science-based, naturally sweetened workout supplements,  LEGION.

When I set out to create this product, I wanted to focus on several primary benefits:

  • Increasing energy and blood flow
  • Reducing fatigue
  • Improving muscular endurance
  • Sharpening mental focus

To accomplish this, I scoured scientific literature and isolated natural, safe compounds that have been proven to deliver the results we want, using clinical dosages that we can viably offer.

The result is PULSE, and here’s what’s in it and why:


Caffeine is a useful pre-workout supplement that can increase muscle endurance and strength. It’s probably the simplest, cheapest way to get more out of your training.

Each serving of PULSE contains 350 mg of caffeine.


Theanine, an amino acid found primarily in tea can, when paired with caffeine, provide several cognitive and ergogenic benefits.

Research has shown that supplementation with theanine and caffeine can reduce the effects of mental and physical stressincrease the production of nitric oxide, which improves blood flow, and improve alertnessfocusattentionmemorymental task performance, and mood.

The clinically effective dosages of L-theanine in the studies cited above range between 100 – 350 mg.

Each serving of PULSE contains 350 mg of theanine.


Beta-alanine, a naturally occurring amino acid, limits the amount of carnosine, a dipeptide, stored in the muscles. As beta-alanine levels increase, so do intramuscular carnosine levels.

Research has shown that supplementation with beta-alanine can reduce exercise-induced fatigueimprove anaerobic exercise capacity, and exhibit mechanisms that can increase lean mass.

meta-analysis of 23 exercises tests of beta-alanine supplementation showed that the clinically effective dosages ranged between 2.6 and 6.4 grams per day, with a median effective dose of just over 5 grams per day.

Each serving of PULSE contains 4.8 grams of beta-alanine.

Citrulline Malate

Citrulline, an amino acid, is sometimes used instead of its counterpart, L-arginine, to stimulate nitric oxide production because it’s better absorbed, and results in higher plasma arginine levels. (L-arginine is unreliable in the mechanism of stimulating nitric oxide production.)

Thus, it’s no surprise that supplementation with citrulline has been shown to improve muscle endurancerelieve muscle soreness, and improve aerobic performance. The effective dosages have been shown to be 6 – 8 grams per day.

Each serving of PULSE contains 8 grams of citrulline malate.


Ornithine, an amino acid, which, along with arginine and citrulline, plays a key role in a metabolic cycle known as the “Urea cycle.” This is the process by which the liver converts ammonia into urea, which is expelled through the urine and sweat, and it impacts physical performance capacity.

Research has shown that supplementation with ornithine can reduce fatigue in prolonged exercisepromote lipid oxidation (the burning of fat for energy as opposed to carbohydrate or glycogen), and increase human growth hormone and insulin-like growth-factor 1 production when paired with arginine.

The clinically effective dosages in the studies cited above were 2, and 2.2 grams per day.

Each serving of PULSE contains 2.2 grams of ornithine.


Betaine, also known as trimethylglycine, is a compound found in plants like beets.

Research has shown that supplementation with betaine can improve muscle endurance,increase strength, and increase human growth hormone and insulin-like growth factor 1 production in response to acute exercise.

The clinically effective dosages in the studies cited above range between 1.25-2.5 grams.

Each serving of PULSE contains 2.5 grams of betaine.

What you won’t find in PULSE is equally special:

  • No artificial sweeteners (naturally sweetened with stevia).
  • No artificial food dyes.
  • No unnecessary fillers, carbohydrate powders, or junk ingredients.

While everyone claims to have the best pre-workout supplement on the market, I can actually back up such claim with real science, and real numbers.

If you want to know what a pre-workout is supposed to feel like…if you want to experience the type of energy rush and performance boost that only clinically effective dosages of scientifically validated ingredients can deliver…then you want to try PULSE.
