Legion Pulse increases energy, improves mood, sharpens mental focus, increases strength and endurance, and reduces fatigue...without the unwanted side effects or crash.


Are you sick and tired of pre-workout drinks that make you sick and tired?

Of upset stomachs, jitters, nausea, and the dreaded post-workout crash?

Do you wish your pre-workout supplement gave you sustained energy and more focus and motivation to train? 

If you’re nodding your head, then you’re going to love PULSE.

No Artificial Sweeteners, Flavouring, Food Dyes, or Unnecessary Fillers

If you compare PULSE’s formulation to anything else on the market, you’ll quickly see that it’s second to none.

What makes it even better, though, is what we left out.

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 and that more research is needed.[43][44][45][46][47][48]

That’s why we’ve chosen to go with the natural sweeteners stevia and erythritol instead.

Research shows that not only are they safe, but they 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.[49][50][51][52]

Many supplements also contain artificial dyes, known as “azo dyes,” such as FD&C Yellow #5 (also known as tartrazine), FD&C Blue #1 (also known as Brilliant Blue), FD&C Red No. 40 (also known as Allura Red AC), and others.

As with artificial sweeteners, the consumption of azo dyes might not be as harmful as some would have you believe, but there is evidence that these chemicals can cause various negative effects in the body.[53][54][55][56][57][58][59][60]

PULSE also isn’t full of cheap carb powders or other fillers.

The only “filler” you’ll find in PULSE is less than one gram of maltodextrin per serving, which is necessary for improving taste and mixability and preventing clumping.

Compare that to the nearly 20 grams of active ingredients in each serving, though, and you’ll see how insignificant it really is.

We wanted to boost energy levels without making you feel like you’re going to have a heart attack.

That’s why we went light on the stimulants and included the amino acid L-theanine, which provides you with a smoother, more enjoyable energy rush.

We wanted there to be no crash.

It’s formulated to provide sustained energy that doesn’t flicker out in the middle of a workout or leave you burned out afterward.

We wanted to actually improve physical performance.

We want to push our limits and see what we’re really capable of. We want heavier lifts, more reps, and better times, and we want a pre-workout supplement that’s actually going to help move the needle.

That’s exactly what you get with PULSE.

We wanted to enhance focus and mood.

PULSE helps by sharpening your mind and elevating your mood, which makes your training more productive and satisfying.

And last but not least, we wanted no upset stomachs, nausea, or other undesirable side effects.

And with the amount of stimulants and other harsh chemicals found in many pre-workout supplements, it’s no surprise that so many people’s stomachs just can’t stand up to them.

Not so with PULSE. It was carefully formulated so there’s no sickness, stomach pains, or uneasiness.

We didn’t invent the pre-workout supplement. We just perfected it.

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

First, PULSE doesn’t contain a concoction of cheap and potentially dangerous stimulants that shock your nervous system and turn your stomach.

In fact, the only stimulant is a moderate dose of caffeine, which is combined with an equal dose of the amino acid L-theanine to smooth out the energy curve and enhance mood and cognition.

The real “magic” of PULSE, though, is in its unique combination of natural substances scientifically proven to increase strength, endurance, focus, and mood.

Furthermore, we’ve included each ingredient at clinically effective levels, which means we’ve used the same doses found in the supporting scientific research.

Let’s take a look at the formulation.


Caffeine helps you lose weight by increasing the amount of energy your body burns throughout the day also improves strength, promotes muscle endurance, and enhances anaerobic performance. [1][2][3]

Clinically effective dosages vary between 3 and 6 mg per kg of bodyweight. [4]


This is the amount of caffeine in one Starbucks grande coffee. Considering the average body weight of most people, it is right in the middle of the clinically effective range for enhancing exercise performance.


L-theanine is an amino acid found primarily in tea that, when paired with caffeine, provides several cognitive benefits. [5][6]

Research shows that supplementation with theanine and caffeine…

  • Reduces the effects of mental and physical stress [7]
  • Increases the production of nitric oxide, which improves blood flow [8]
  • Improves alertness, focus, attention, memory, mental task performance, and mood [9][10][11][12][13][14][15]

The clinically effective dose of L-theanine ranges between 100 and 250 mg, and when combined with caffeine, it is often found at a 1:1 ratio


Citrulline Malate

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.

We chose citrulline malate over L-citrulline for two reasons:

1. It’s likely that malic acid confers additional health and performance benefits. [16][17]

2. It’s the form used in most studies demonstrating the performance benefits associated with L-citrulline.

We also chose citrulline malate over the better-known “nitric oxide booster” L-arginine because it’s better absorbed and thus more effective in enhancing physical performance. [18]

Research shows that supplementation with citrulline…

Clinically effective dosages in the studies cited above range from 4 to 10 grams per day.



Beta-alanine is a naturally occurring amino acid that regulates the amount of the molecule carnosine that can be stored in the muscles. [24]

One of carnosine’s roles in our muscles relates to the regulation of acidity levels.

When a muscle contracts repeatedly, it becomes more and more acidic. This, in turn, impairs its ability to continue contracting, until eventually it can no longer contract at all.

This is one of the ways that muscles become fatigued.[25]

Carnosine counteracts this by reducing muscle acidity, thereby increasing the amount of work the muscles can do before they become fatigued.[26]

Now, as beta-alanine levels in the body rise, so do intramuscular carnosine levels, and this is why research shows that supplementation with beta-alanine...

The clinically effective dose of beta-alanine ranges from 2.6 to 6.4 grams per day, with a median effective dose of about 5 grams per day.


It’s worth noting that a common harmless side effect of beta-alanine supplementation is a mild prickling, itching, or tingling of the skin. [38]

Due to the proper dosing of beta-alanine in PULSE, you’re likely to experience this side effect.


Betaine, also known by its scientific name trimethylglycine, is a compound that’s found in beets and other plants.

It’s gaining more and more popularity among athletes for good reason: research shows that it boosts muscle endurance and increases strength. [39][40]

The mechanism of how it accomplishes this isn’t fully understood yet, but several hypotheses are being investigated. The one currently considered most correct relates to the “cellular swelling” effect of betaine, which protects cells from exercise-induced damage and thus improves performance.[39][41]

The clinically effective dose of betaine ranges between 1.25 and 2.5 grams.



L-ornithine is an amino acid that, 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 it affects physical performance capacity.

Research has shown that supplementation with ornithine…

  • Reduce fatigue in prolonged exercise. [42]
  • Promote lipid oxidation (the burning of fat for energy as opposed to carbohydrate or glycogen). [42]

The clinically effective dose of ornithine is between 2 and 3 grams per day.


The Bottom Line

PULSE increases energy, improves mood, sharpens mental focus, increases strength and endurance, and reduces fatigue...without unwanted side effects or the dreaded post-workout crash.

The reason it’s so effective is simple:

Every ingredient is backed by peer-reviewed scientific research and is included at clinically effective levels.

It also contains no harsh or dangerous stimulants, which means you get to enjoy a smooth pre-workout energy rush that pumps you up without burning you out.

PULSE is 100% naturally sweetened and flavoured too. It contains no chemical dyes, cheap fillers, or other unnecessary junk, so you don’t have to worry about potential health effects.
