Legion Pulse Pre-Workout Review (2024): Expensive, Yes, But Worth It?

Really good marketing can make a so-so product seem like the best thing since sliced bread, am I right? And many times, food products that claim to be “all-natural” or “a good source of vitamins and minerals” are not at all, so we as consumers shoulder a lot of the burden to educate ourselves. 

Team GGR is here to help—at least as far as supplements go—and in this Legion Pulse pre-workout review, we’re going to dissect this popular “100% natural” pre-workout to decide whether it’s all it’s cracked up to be.

We’ve Taken Lots for You 

Our team of certified personal trainers, nutrition coaches, and nutrition experts really puts our money where our mouths are, personally testing 95% of the products we write about.

We want to be able to experience each product for ourselves, so we can recommend—or not recommend—them in full confidence. I’ve personally tested dozens of the best pre-workouts, BCAAs, creatine supplements, and more, just to provide you with an honest review—we really care, OK?

A Quick Look at Legion Pulse

Legion Pulse is a gluten-free, vegetarian pre-workout supplement with 100% nature-based ingredients, meaning every ingredient is sourced from plants and animals, according to the company, similar to all the best vegan protein powders. It’s designed to give you an energy boost, support increased strength, and cut down on fatigue with its clinically effective doses of key ingredients like l-citrulline dl-malate, caffeine anhydrous, and beta-alanine. 

Before You Buy

• You can purchase Pulse with caffeine, or in a stim-free version  
• Seasonal flavors tend to go on sale, so check the site for a deal 
• Know that there are only 20 servings in a container, so if you like Pulse, you’ll have to purchase it frequently

Is Legion Pulse Worth It?

If you’re looking for a product to give you an energy boost before your workout to help you build muscle, sustain endurance, and generally kick butt, but you aren’t crazy about lots of the artificial sweeteners, dyes, and various stimulants that are packed into many pre-workouts, Legion Pulse could be a good option.

Experience Using Legion Pulse 

I’ve used Legion Pulse before many-a-workout, some of which were CrossFit classes where you push yourself to the absolute max on the regular, and some of which were heavy lifting days at the gym. Overall, the taste isn’t my favorite, but I like that it’s a nature-based product and the effects I experience are worth it. Let’s dive into more specifics.

Price Per Serving

Pulse is not cheap—most flavors cost about $2.25 per serving, which is on the very high end for pre-workout. Plus, the container, which costs $44.99, only contains 20 servings, so if you take pre-workout frequently, you’ll run out of this quickly. 

That being said, Legion Athletics is fully transparent about everything that’s in Pulse, the product is third-party tested, and unfortunately, quality ingredients just cost more inherently. So even though it’s expensive, is Pulse a good value? I think so.

Formulation

One of our sports nutrition experts who reviewed this product, Dr. Krissy Kendall, was impressed with the formulation of Legion Pulse, particularly because each key ingredient is dosed at research-backed levels, and there are no proprietary blends. The latter is a way for companies not to disclose the exact ingredients and amounts of those ingredients in a supplement, which we’re not a huge fan of. 

But back to Pulse: To start, there are 8 grams of l-citrulline malate, a nitric oxide enhancer (which increases blood flow) that has proven benefits¹ on both strength and muscular endurance at that dosage. 

Next is beta-alanine, which is present at a dose of 3.6 grams. Beta-alanine is a non-essential amino acid that has been shown to enhance athletic performance, and while it is slightly underdosed in Pulse as far as its maximum potential effects—most research² looks at a dose of about 6 grams daily—a smaller amount may help prevent paresthesia, the harmless tingling feeling sometimes caused by this compound. There are also 2.5 grams of betaine anhydrous, which has been studied for its effects on body composition³, muscle protein synthesis⁴, and power output ⁵ in just that dosage. 

To increase energy, there’s a whopping 350 milligrams of caffeine in one serving of Pulse, which is the equivalent of 3.5 cups of coffee—hello, world! To potentially help enhance the effects of the caffeine, 350 milligrams of L-theanine are also present—research⁶ has demonstrated that caffeine paired with L-theanine could be beneficial in improving performance during cognitive tasks. 

And lastly, there are 300 milligrams of Alpha-GPC, which is a chemical that may positively affect cognitive function. Recent research has shown that it can benefit motivation⁷ and memory.

Pulse is sweetened with both erythritol and stevia leaf extract, and there are a handful of other ingredients like potassium citrate and calcium carbonate present in small amounts. Overall, each ingredient in this pre-workout serves a purpose, and is clearly identified on the label. 

Taste and Solubility

Now what everyone really wants to know: How does it taste? Well, for starters, there are 18 flavors of Pulse with caffeine, and six caffeine-free flavors—we love to see it! 

I tried the Blue Raspberry version with caffeine, but admittedly, have not taken a full dose in one sitting as that much caffeine scares me. That said, I think Blue Raspberry Pulse is very sweet (and a touch bitter) with a slight aftertaste. This flavor isn’t my favorite—next time I might try something a bit sexier, like Sour Candy—but, I can get it down in a few minutes without any issue. 

Most customer reviewers love the flavor variety, and fan-favorite flavors include Fruit Punch, aforementioned Sour Candy, and Strawberry Kiwi based on recent reviews.

I’m also happy to report that Pulse mixes well in a shaker with the recommended 10 to 12 ounces of water, leaving behind no visible clumps or floaties. Amen. 

Side Effects

Typical side effects of pre-workout can include increased strength, power, and muscle endurance, but also jitters, itchiness, increased heart rate, and more. As mentioned, I only take about a half a dose of Pulse, but that’s all I need to power through a workout—it gives me energy for sure, and I haven’t experienced any of the negative stuff. Many other reviewers tend to agree, saying that it provides amazing energy without that infamous stimulant-induced post-workout crash. 

Third-Party Testing 

Third-party testing is important because although the supplements industry in America is regulated by the FDA, the FDA doesn’t approve these products⁸. This means that some dietary supplements are marketed and sold to consumers without the FDA knowing—wild, huh?

An independent organization like NSF, Informed Choice, or in Legion Athletics’ case, Labdoor, has verified that what’s on the label of Pulse is actually what’s in the container, meaning there are no banned substances and everything is as potent as what Legion Athletics claims. 

Especially if you’re an athlete, we can’t stress enough how important third-party testing is in supplements like pre-workout drinks—know what you’re drinking, people!

Product Highlights

• Naked Energy is a vegan pre-workout supplement formulated with just 10 ingredients and nothing artificial. 
• Three flavors are available: Fruit Punch, Citrus, and Unflavored.

Pros & Cons

Pros

• Formulated with just 10 ingredients
• Affordable at less than $1 per serving
• Available in unflavored option
• Vegan

Cons

• Small dose of creatine
• No nitric oxide boosters, so don’t expect a muscle pump

Bottom Line

If you’re looking for a vegan pre-workout supplement, Naked Energy may be a good choice. Made with just 10 ingredients and nothing artificial, it was designed to support increased energy without the fillers.

If natural pre-workout is up your alley, Naked Energy is another option that should be on your radar. 

With only 10 ingredients, it, too, does not contain any additives or artificial sweeteners; just beta-alanine, creatine, arginine, B vitamins, and caffeine. It’s available in four options: Unflavored Pre-Workout, Fruit Punch Pre-Workout, Citrus Pre-Workout, and Stim-Free Pre-Workout, plus it’s third-party tested to ensure that what you see on the label is what you get. 

Although there are not nearly as many flavor options, and it’s missing some key ingredients like l-citrulline malate, Naked Energy is quite a bit cheaper at about $1.20 per serving. Also, the Unflavored option is almost wholly unflavored, save for a slightly bitter aftertaste, and mixes well with many beverages, which we like for versatility.

Product Highlights

• Powerful ingredients
• Gives a solid boost of energy
• Dissolves well
• Affordable price per serving

Pros & Cons

Pros

• Powerful ingredients
• Gives a solid boost of energy
• Can aid in training performance
• Dissolves well
• Affordable price per serving

Cons

• Some users report unpleasant aftertaste
• Gives some people headaches
• Some experience tingling in the face

Bottom Line

If you’re looking for an affordable pre-workout drink from a big-name supplement company, give C4 a look.

Cellucor C4 is arguably the most popular pre-workout on the planet, due to its beginner-friendly nature, yummy flavors, and low price point. 

At $0.78 per serving it is a steal, but its ingredients are underdosed from a peer-reviewed research standpoint, including just 1.6 grams of beta-alanine, 1 gram of creatine, 1 gram of citrulline malate, and 215 milligrams of caffeine from an energy blend. It’s also not third-party tested, although Cellucor is a reputable brand. 

If you’re just starting out or are on a major budget, C4 might be a good option for you; otherwise, shop around. Read our full Cellucor C4 review for our complete thoughts on this pre-workout.
