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.

Clinically Effective Ingredients & 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.

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 with Globally Sourced Ingredients

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 supplement.

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.

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.
