Welcome to my Legion Pulse pre workout review. 

One of the biggest barriers to working out is fatigue. Whether we’re sore from our last session or just don’t feel like getting out of bed to go to the gym, sustaining motivation is the challenge.

This is what pre-workouts are aimed at resolving. They’re intended to give us energy, help with recovery, and enhance our focus. 

The trouble is, there are hundreds of pre-workout supplements out there. I’ve reviewed dozens of them, paying careful attention to which ones are actually beneficial and effective. 

As a health researcher, it’s very important to me that the products we recommend are backed by science and include optimal dosages and effective ingredients. 

Legion Pulse preworkout ticks a lot of the boxes for quality supplements. But is it right for your lifestyle, preferences, and budget?

I’ll break it all down, from ingredients and alternatives to pros and cons. 

Keep reading my Legion Pulse review to learn all about it.

They carry many other supplements, including whey protein, greens, sleep aids, and energy boosters.

What is Legion Pulse Pre Workout?

legion pulse pre workout review

Legion Pulse Pre-Workout is advertised as a 100% natural pre-workout. It is designed to deliver a wide range of benefits, including energy, focus, strength, power, and endurance. 

Plus, they say it gives you all the energy with no crash later. Citrulline, beta-alanine, and caffeine are just a few of the many science-backed ingredients in Legion Pulse. 

Is Legion Pre Workout FDA-approved?

Legion Pre Workout is not FDA-approved since the FDA doesn’t approve or reject nutritional supplements. 

With that being said, all of the individual ingredients in Legion Pulse are deemed safe by the FDA. 

Things to Consider Before Buying Legion Pulse Pre Workout

Before buying Legion Pulse Pre Workout, you want to make sure that it’s the right product for you. This often depends on the ingredient profile, dosages, and any safety concerns, among other factors. 

Here are a few points of interest that can help inform your buying decision.


Now, when looking at Legion Pulse, it does contain a very high dose of caffeine, so it is not for stimulant-sensitive people. However, it can be a huge draw for people who want a burst of energy.

However, as we’ll note in more detail later, they also offer a stim-free version for people who are sensitive to caffeine.

Other Ingredients

Other than that, most people who want to experience an overall increase in workout performance may benefit from Legion Pulse Pre Workout.

After all, it contains clinically-researched ingredients. And all of the ingredients are generally safe to consume. I’ll share more about the ingredients in a few minutes.


Legion Pulse Pre Workout has zero artificial flavors, colors, or preservatives. And Legion Pulse is also lab tested for purity and potency.


Lastly, you want to be mindful of the price. If a pre-workout is really effective but drains your wallet every month, it might not be a good choice. 

Pulse Pre Workout seems to be reasonably priced at around $36 for 21 servings. 

Legion Pre Workout Features

Legion Pre Workout has many features that stand out. These include its natural ingredients, natural sweeteners, clinically effective dosages, lab-tested formula, caffeine/l-theanine combo, and other factors.

Natural Ingredients

Many pre-workouts are often filled with artificial flavors, chemicals, and other garbage that can potentially harm the body and mind. 

However, Legion Pulse claims to contain only natural pre-workout ingredients that the body recognizes and can benefit from. 

Natural Sweeteners

Similarly, Legion Pulse only uses natural sweeteners for flavor, including stevia and erythritol. Artificial sweeteners have been known to disrupt many aspects of health, including the brain and gut. 

But Legion Pulse is free from these, so you likely don’t have to worry as much. 

Clinically Effective Dosages

A pre-workout can have the best ingredients in the world. But if they’re not properly dosed, it won’t make much of a difference. 

Fortunately, Legion Pre Workout claims to offer only clinically effective dosages for all of its ingredients. This includes optimal dosages for time-tested ingredients, such as caffeine, beta-alanine, and citrulline malate.

In turn, this may lead to maximal benefits for energy, strength, pumps, endurance, and other aspects of workout performance.

Lab Tested

legion pulse preworkout features

Another concern with supplements is their overall safety. Legion Pulse Pre Workout is lab-tested in an accredited laboratory.

This ensures that you’re actually getting what they say. It also confirms product potency and purity. 

Caffeine/L-Theanine Combo

Almost all pre-workouts have caffeine in them, but not nearly as many also have L-theanine. Without L-theanine, caffeine can lead to jitters, anxiety, and other uncomfortable symptoms. 

But Legion Pulse combines caffeine with an equal dose of l-theanine, which may have synergistic effects while also decreasing the side effects of caffeine. 

Stim-Free Version

We just talked about caffeine and L-theanine, but these two are not in the stim-free version. 

This can be a solid option for people who are sensitive to stimulants but still want to increase workout performance. 

Similarly, it also may give users the option to take a pre-workout later in the day without having to deal with trouble sleeping later on. 

Overall, including a stim-free version of Legion Pulse likely makes it that much more appealing to a wider range of people. So, you can truly choose the one that best suits your needs.

Does Legion Pulse Pre Workout really work?

It seems very likely that Legion Pulse Pre Workout will work effectively as a pre-workout supplement. 

Individual results can vary, of course. 

The ingredients may offer a wide variety of workout performance benefits to many different people. 

Overall, it should be effective for the things you care about most from a pre-workout. That is, it should help you increase strength, delay fatigue, improve focus, enhance energy, and give you better pumps. 

These aren’t guaranteed. But it does seem like Legion Pulse is definitely one of the better pre-workouts out there.

Legion Pulse Pre Workout Ingredients

Legion Pulse Pre Workout doesn’t contain a boatload of ingredients, sticking to ones that are actually beneficial.

Below, we’ll go over each of the Legion Pulse ingredients to see how effective they are. Plus, we’ll see if they use the proper dosages based on research. 

The ingredients in Legion Pulse that we’ll take a look at are:

  • Caffeine
  • L-Theanine
  • Citrulline Malate
  • CarnoSyn® Beta-Alanine
  • AlphaSize® Alpha-GPC
  • Betaine

All dosages listed below are based on the serving size, which is two scoops.

Also, remember that caffeine and L-theanine are not in the stim-free version. But all other listed ingredients and dosages are the same in the two versions.

Caffeine (350mg)

Caffeine is one of the most widely used ingredients in pre-workouts, and for good reason.

It blocks adenosine receptors, which can cause an increase in serotonin, dopamine, norepinephrine, and other neurotransmitters.

These can increase mood, alertness, focus, and delay fatigue. Plus, the stimulatory effects of caffeine on the central nervous system (CNS) can improve endurance, strength, and power. 

Legion uses 350mg in Pulse, which is a solid dosage based on the recommended guidelines of 3 to 6mg/kg. 

Effective dosage according to Examine: 200 to 500 mg

L-Theanine (350mg)

L-theanine is an amino acid found naturally in green tea. It can increase alpha waves and GABA levels in the brain. This may provide a calm focus while decreasing stress and anxiety.

Plus, research shows that combining theanine with caffeine can enhance attention, alertness, and overall cognition.

Effective dosage according to independent analysis: 200mg

Citrulline Malate (8g)

Citrulline is a combination of the amino acid L-citrulline and malic acid. Citrulline malate can increase arginine and nitric oxide production. This leads to enhanced blood flow to the muscles. 

Additionally, this compound may enhance ATP levels, which provides further benefits for energy. 

Most studies have found benefits for citrulline malate supplementation for both exercise performance and recovery. But it’s not entirely conclusive. 

It generally has been shown to reduce fatigue, enhance power, and increase endurance. 

Effective dosage: 6,000 to 8,000mg

CarnoSyn® Beta-Alanine (3.6g)

legion pulse ingredients

CarnoSyn® is a trademarked form of beta-alanine. Beta-alanine is an amino acid known for its ability to increase muscle carnosine stores. This is important since carnosine may play a critical role during exercise. 

Plus, beta-alanine acts as a pH buffer, which can delay fatigue. 

Overall, beta-alanine has been shown to increase exercise capacity, especially in short-duration exercises lasting 1 to 10 minutes.

Effective dosage: 3.2 to 6.4g

AlphaSize® Alpha-GPC (300mg)

AlphaSize® is a trademarked form of Alpha-GPC, which is essentially a choline compound. 

Alpha-GPC can increase choline levels, which in turn increases acetylcholine in the brain and CNS. Acetylcholine is known for its roles in focus, memory, and even muscle contractions and strength. 

Limited studies have shown that Alpha-GPC may enhance power and strength, but more research is needed. 

Effective dosage according to Examine: 300 to 600 mg

Betaine (2.5g)

Betaine (also known as trimethylglycine) has a number of functions that may help improve exercise performance.

First, it acts as an osmolyte, which helps the cells retain water and maintain fluid balance. And this could provide the muscle cells with hydration during exercise.

Also, betaine is known to increase creatine and ATP synthesis, which can aid strength and power. 

However, current research is inconclusive on betaine’s effects, although some studies have shown increased strength and power from betaine.

Estimated effective dosage: 2.5g

Available Flavors

Legion Pulse’s stimulant pre-workout comes in a bunch of different flavors (15 to be exact!). The flavor varieties are:

  • Blue Raspberry
  • Mojito
  • Fruit Punch
  • Arctic Blast
  • Pink Lemonade
  • Tropical Punch
  • Watermelon
  • Strawberry Kiwi
  • Blood Orange
  • Blueberry Lemonade
  • Cherry Limeade
  • Grape
  • Green Apple
  • Sour Candy 
  • Strawberry Margarita

  • Blue Raspberry
  • Fruit Punch
  • Green Apple
  • Tropical Punch

Legion Pulse Pre Workout Pros and Cons

A key part of this Legion Pulse Pre Workout review is going over the pros and cons. Now, Legion Pulse definitely has more pros than cons. So, let’s take a look at some of the main points to consider. 


  • All ingredients are at clinical dosages (very rare!)

How to Use Legion Pulse Pre Workout

Recommended Dosage

legion supplement recommended dosage

First-time users of Pulse should assess tolerance by taking just one scoop 15 to 30 minutes before exercise.

If this is well-tolerated, users are recommended to take the full clinically-effective dose, which is two scoops. This should also be taken 15 to 30 minutes before working out.

Stacking a Pump Pre-Workout (Stim-Free)

For even greater potential effects, you may want to consider stacking this Pulse supplement with a pump pre-workout. 

Pump pre-workouts are pre-workout supplements that only contain ingredients to enhance blood flow and pumps. They don’t contain any stimulants. Rather, they just contain citrulline, arginine, and other ingredients for maximum pumps.

This is often combined with other pre-workouts such as Legion Pulse to get even greater results. 

Mainly, you may want to stack Legion Pulse with a pump pre-workout if you are interested in getting maximum pumps while also getting the benefits of a regular pre-workout (strength, energy, power, etc.). 

Real Customer Legion Pulse Pre Workout Reviews

Legion supplements are generally highly rated. And Legion Pulse is no different, with an average 4.6 out of 5 rating on their website, based on over 3,000 reviews. 

Listed below are some examples of real customer reviews of Legion Pulse Pre Workout:

Since I have started taking a full clinical dose of Legion Pulse before every workout, I have been killing it every day in the gym, even after getting used to constantly taking it day after day! I know that if I take Pulse for a workout I can go hours confidently and still perform well in all lifts and exercises!”


“This pre workout is great ! It doesn’t give me a crazy tingle or a crash after my workout. It also tastes great and has so many flavors to enjoy.”


“I take Pulse before every workout. Provides excellent energy and focus for the workout!”

-Chris B.

“I love this pre workout, it really gets me to push myself. The ingredients are very clean which is a plus. The taste makes it a little hard to get down, but I’d repurchase.”

-Amber D.

Everything about it is alright. I am happy that it’s all natural and everything is properly dosed, but the blue razz flavor just doesn’t stack up against other brands. It doesn’t give me that much of a boost in the weight room and I don’t find that it gives me any benefits. I only feel anything when I am extremely tired or unmotivated”

-Davis H.

Better Overall Workout Performance

Combined, these benefits simply make Legion Pulse a potential pre-workout for better overall workout performance. 

More reps, heavier weight, faster sprints…these are some of the things you may experience when taking Legion Pulse.

Potential Legion Pulse Pre Workout Side Effects

Like all supplements, Legion Pulse has potential side effects. 

Due to its high caffeine content, Legion Pulse may increase anxiety, jitters, and nervousness. 

Taking it too close to bedtime may also lead to insomnia or restlessness.

Of course, these side effects are only for the regular version, not the stim-free one.

Also, Legion Pulse may have certain gastrointestinal side effects, including upset stomach, bloating, and nausea.

Additionally, beta-alanine may cause a tingling sensation in some people. This is harmless, but may be uncomfortable for some.

Legion Pulse Pre Workout Price

Each container of Legion Pulse comes with 21 servings (42 total scoops). The regular price is $44.99 ($2.14/serving), but you can choose the Subscribe & Save option to save 20%. That lowers the price to $35.99 ($1.71/serving). 

Legion Pulse pre-workout is a relatively expensive product. But this price certainly seems fair considering the high doses of all of the ingredients in it. 

As a result, the overall value of what you’re paying for should be quite high. 

And you can always try using just one scoop to see if that gives you your desired results.
