Scientific Review Board

Our scientific review board of nutritionists, dietitians, molecular biologists, bariatric doctors, and other accredited experts is responsible for reviewing every article, podcast, and video we produce to ensure they’re evidence based, accurate, trustworthy, and current.

Thanks to their connections, credentials, and academic experience, this team of MDs, PhDs, and other professionals has access to a wealth of research published in the largest and most prestigious journals in the world, which allows them to not only review individual studies but also analyze the overall weight on the evidence on any and all topics related to diet, exercise, supplementation, and more.

Additionally, they have thousands of hours of combined hands-on experience in their respective fields to draw upon, which provides a level of clarity and judgment that's otherwise unattainable.

Understand Our Process

We follow a detailed, rigorous, multi-step process to create content that meets the highest standards of clarity, practicality, and scientific integrity.

Here’s how it works:

Step 1: Scientific Research

Our research associates continually monitor emerging trends in nutrition, exercise, and supplement science, clinical guidelines, and medical practice recommendations and provide our editorial team with fresh, up-to-date research on a wide variety of topics.

Step 2: Content Creation

Our editorial team drafts articles and outlines for podcasts and videos based on the most current and evidence-based scientific understandings of the matters being discussed.

Step 3: Scientific Review

Our scientific review board reviews the content to ensure all key information and claims are backed by high-quality scientific research and explained simply and precisely.

Our "No Return Necessary"
Money-Back Guarantee

If you don’t like something of ours, guess what happens next?

No, we don’t request you deliver it to a PO box in the Gobi Desert by carrier pigeon. Nor do we ask you to fill a cursed inkwell with orc’s blood and demon saliva and then use it to complete reams of return forms written in ancient Cyrillic script.

We just . . . wait for it . . . give you your money back. Holy moo cows. And that means you can say "yes" now and decide later.

Free Worldwide Shipping & Returns

Many companies use shipping and handling fees to increase their profit margins, but here at Legion, we hate profits, so our shipping is free!

Okay, so we do dig on profits, but we also go in for happy customers, and free shipping works like gangbusters. So, if you live in the United States, your order ships free regardless of order size, and if you live elsewhere, your order ships free when it’s over $199.

Why the restriction on international orders? Unfortunately, shipping abroad is very expensive, and if we didn’t require a minimum order size, we’d lose a lot of money. But! We're also hustling to improve our international logistics and will be passing our savings along to our international customers.

Also, if you don’t absolutely love our stuff for whatever reason, we don’t request you deliver it to a PO box in the Gobi Desert by carrier pigeon.

We just . . . wait for it . . . give you your money back. No returns. No forms. No nonsense. Holy moo cows.

That means you can say “yes” now and decide later. You really have nothing to lose.

Clinically Effective Doses

Many ingredients in supplements don’t have any scientifically validated benefits, and many ingredients that do are often underdosed to the point of irrelevance.

That’s why we only use the choice ingredients and precise doses shown to be effective in peer-reviewed scientific studies.

Clinically Effective Doses

You need more than great ingredients to make great products—you also need proper doses. That’s why we use the precise doses of ingredients shown to be effective in peer-reviewed scientific studies.

100% Natural Ingredients

“Natural” doesn’t always mean “better,” but in many cases, natural ingredients are superior to artificial ones for various reasons, including purity, safety, and efficacy.

That’s why all of our ingredients in all of our products come from plant and animal sources, including sweeteners, colors, and flavors.

Made in USA

If you want to ensure the supplements you’re swallowing every day are safe and effective, you want products produced in the USA.

That’s why all of our supplements are made in America in NSF-certified and FDA-inspected facilities that operate in accordance with the Current Good Manufacturing Practice (cGMP) regulations.

Lab Tested

Did you know that supplements can contain dangerously high levels of toxins like lead, arsenic, and cadmium?

That’s why we test every ingredient of every supplement we produce for heavy metals, microbes, allergens, and other contaminants and ensure they meet the strict purity standards set by the FDA.

Naturally Sweetened & Flavored

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.

That’s why all of our supplements are naturally sweetened and flavored and contain no artificial food dyes, fillers, or other unnecessary junk.

Science-Backed Ingredients

Many ingredients in supplements don’t have any scientifically validated benefits. That’s why we only use choice ingredients shown to be effective in peer-reviewed scientific studies.

No Chemical Junk

“Natural” doesn’t always mean “better,” but in many cases, natural ingredients are superior to artificial ones for various reasons, including purity, safety, and efficacy.

That’s why all of our ingredients in all of our products come from plant and animal sources, including sweeteners, colors, and flavors.

OUT OF STOCK

Security Check

Please click the checkbox below. We apologize for the inconvenience.

Some popular pre-workouts are all-natural. Some contain the right mix of high-quality ingredients. Some provide clinically effective doses. But only Pulse checks each of these boxes.

Pulse doesn’t just “contain natural ingredients''—every ingredient is naturally sourced from plants and animals. Pulse contains no artificial or synthetic substances of any kind.

Every serving of Pulse contains 15.1 grams of active ingredients that have been shown to be safe and effective in peer-reviewed scientific research.

Every active ingredient in Pulse is backed by published scientific studies that show benefits in healthy humans.

Pulse contains no harsh stimulants that wind you up and burn you out. Instead, it contains a 1:1 ratio of caffeine and L-theanine, which produces a smooth energy rush and comfortable comedown.

We carefully examined 508 pages of scientific research to find out exactly what should and shouldn’t be in a pre-workout drink.

Every bottle of Pulse is guaranteed to provide exactly what the label claims and nothing else—no heavy metals, microbes, allergens, or other contaminants.

While these types of chemicals may not be as dangerous as some people claim, studies suggest that regular consumption of them may indeed be harmful to our health. And that’s why we don’t put any of them into our products.

Before you buy a sports supplement, you should know that it's clean, safe, and transparent. And that's exactly what Labdoor's third-party testing and certification means.

It's hard to know for sure, but this probably makes Pulse the most-popular all-natural pre-workout supplement in the world.

"No Return Necessary" Money-Back Guarantee

If you don’t absolutely love this product, just let us know, and we’ll give you a full refund on the spot. No forms or return necessary.

Labdoor Tested for Purity

Analyzed for purity and potency in a state-of-the-art ISO 17025 accredited lab by Labdoor, the gold standard of third-party lab testing.

100% Natural Ingredients

This product doesn’t just “contain natural ingredients’’—every ingredient is naturally sourced from plants and animals. This product contains no artificial or synthetic substances of any kind.
