Pulse Stim-Free | Pre-Workout


Many companies offer a money-back guarantee because they know the majority of dissatisfied customers aren’t going to go through the hassle of actually returning the product to get their money back. We don’t play these games because we don’t have to, the quality of our products makes it unnecessary.

If you order any of our supplements for the first time and don’t like it, you can keep it. Just notify us and we’ll give you a full refund on the spot. No complicated forms and no return necessary.

To protect ourselves from fraud, the It’s-On-Us guarantee is only valid for first time purchases of a product, and redeemable up to three months after purchase. If you bought more than one bottle of a supplement on your first purchase and don’t like it, we would ask that you send the unopened bottles back to us for a refund because we can put them back into our sellable inventory.

When you start comparing actual numbers, you can quickly see that one scoop of PULSE — ½ of a serving — contains about double the effective ingredients of our best competitors.

And a full serving, which provides you with clinically effective dosages, is double that. While everyone claims to have the best products on the market, we believe we can actually back up such a claim with real science and real numbers.

Compare the PULSE formulation to any other pre-workout drink on the market, and it’s easy to see how inferior our competitors’ products truly are.

If you want to know what a pre-workout is supposed to feel like…if you want to experience the type of energy rush and performance boost that only clinically effective dosages of scientifically validated ingredients can deliver…if you want to avoid any potential issues arising from regular intake of artificial sweeteners and food dyes…then you need to try PULSE.

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 more focus and motivation to train? Do you wish it gave you noticeably better workouts and helped you hit PRs?

If you’re nodding your head, then you’re going to love this stimulant-free version of PULSE.

You see, when we set out to create it, we wanted to accomplish several things.

We wanted to boost workout performance without any stimulants.

It’s hard to have a good workout when you’re tweaked out on too many stimulants and more focused on not dying than anything else.

Many people also exercise in the late afternoons and evenings, and even a small amount of caffeine taken before these workouts can be enough to ruin their sleep later that night.

Furthermore, many people enjoy caffeine and tolerate it well, but would prefer to consume it in other ways than a preworkout supplement (coffee and tea, for instance).

All that's why this version of PULSE contains absolutely no stimulants, which means you get to reap all the performance benefits while also being able to choose exactly how much caffeine you have every day and when you have it.

We wanted to actually improve physical performance.

If you’re like us, training is more than just moving your body.

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.

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

Nothing kills a workout faster than a bad case of the queasies.

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 this stimulant-free version of 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, this version doesn't contain any stimulants whatsoever, so you never have to worry about after-effects like the dreaded "postworkout crash".

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

These key ingredients include citrulline malate, beta-alanine, Alpha-GPC, and betaine, and each is backed up by peer-reviewed research demonstrating clear benefits.

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.

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. [1][2]

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. [3]

Research shows that supplementation with citrulline malate…

  • Improves muscle endurance [4][5][6]
  • Relieves muscle soreness [20]
  • Improves aerobic performance [7][8]

The clinically effective dose of citrulline malate ranges 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. [9]

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.[10]

Carnosine counteracts this by reducing muscle acidity, thereby increasing the amount of work the muscles can do before they become fatigued.[11]

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. [23]

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. [24][25]

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][26]

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



Alpha-Glycerophosphocholine (Alpha-GPC) is a compound that increases the activity of acetylcholine in the brain, which is a chemical used by nerves to communicate with each other (neurotransmitter).

Alpha-GPC is a rather unique molecule for several reasons:

  1. It isn't gobbled up by the choline-loving liver and thus can reach the brain and act on it directly.

  2. It helps your body maintain sufficient levels of acetylcholine, which in turn supports optimal physical and mental performance.

  3. It provides your body with glycerophosphate, which is a substance in the membranes of nerve cells that supports brain health and function.

All this is why research shows that supplementation with Alpha-GPC can...

  • Increase power output[27]
  • Mitigate cognitive decline as we age[28]
  • Increase growth hormone levels[29]
  • The clinically effective dosage of Alpha-GPC is between 150 and 1,200 milligrams, with the range of 150 to 300 milligrams sufficient for cognitive benefits and higher dosages required for affecting dementia.


No Artificial Sweeteners, Flavoring, 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.[31][32][33][34][35][36]

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 a lower cholesterol profile, improved blood glucose control, potential anti-cancer effects, lower blood pressure and inflammation levels, and more.[37][38][39][40]

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.[41][42][43][44][45][46][47][48]

And while artificial flavors appear to be benign, they just aren’t necessary. Natural flavors taste equally good.

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

While eating carbs before working out is an easy way to boost your performance, we don’t believe that carb powders belong in pre-workout drinks. You can just eat food for that.

The only “filler” you’ll find in PULSE is about two grams 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.

The Bottom Line

PULSE 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.

This version of PULSE also contains no stimulants, which means you get to reduce or restrict your caffeine intake as desired.

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

If you want to feel focused, tireless, and powerful in your workouts…and if you want to say goodbye to the pre-workout jitters, upset stomachs, and crashes for good…then you want to try PULSE.
