When we set out to create stim-free Pulse, we wanted to achieve several things . . .

1. 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 pre-workout supplement (coffee and tea, for instance).

All that’s why stim-free 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.

2. We wanted to actually improve physical performance.

If you’re like us, training is more than just exercise and 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 stim-free Pulse.

3. 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 stim-free Pulse. It was carefully formulated so there’s no sickness, stomach pains, or uneasiness.

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.

L-citrulline turns into another amino acid in the body known as L-arginine, which increases the production of a gas known as nitric oxide that widens blood vessels and improves blood flow.[1][2]

Interestingly, research also shows that supplementing with L-citrulline accomplishes this better than supplementing directly with L-arginine, which is very hit or miss in its effectiveness.[3]

Additionally, for the purposes of a pre-workout supplement, citrulline malate is superior to L-citrulline for two reasons:

  1. It’s likely that malic acid confers additional health and performance benefits. [4]

  2. It’s the form used in most studies demonstrating the performance benefits associated with L-citrulline.

All this is why research shows that supplementation with citrulline malate . . .

  • Improves muscle endurance[5][6][7]
  • Relieves muscle soreness[8]
  • Improves aerobic performance[9][10]

The clinically effective dose of citrulline malate is between 4 and 10 grams.

Stim-free Pulse contains 8 grams of citrulline malate per serving.

CarnoSyn® Beta-Alanine

Beta-alanine is a naturally occurring amino acid that regulates the amount of the molecule carnosine that can be stored in the muscles. [11]

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.[12]

Carnosine counteracts this by reducing muscle acidity, thereby increasing the amount of work the muscles can do before they become fatigued.[13]

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 is between 2.6 and 6.4 grams.

Stim-free Pulse contains 3.6 grams of CarnoSyn® beta-alanine per serving.

We chose this amount per serving because it provides significant performance benefits while also minimizing the common and harmless side effect of a mild prickling, itching, or tingling of the skin.[28]

Due to the proper dosing of beta-alanine in stim-free Pulse, you’re likely to experience this side effect.

AlphaSize® Alpha-GPC

Alpha-glycerophosphocholine (also known as alpha-GPC and glycerophosphocholine) is a compound that contains two molecules known as choline and glycerophosphate.

Choline is a nutrient that’s vital for brain health and function, and glycerophosphate is a substance that helps transport choline to the brain.

When ingested, alpha-GPC increases the activity of a chemical in the brain known as acetylcholine, which is used by nerves to communicate with each other, and provides the brain with glycerophosphate, which can improve its health and function.

This is why research shows that supplementation with alpha-GPC . . .

  • Increases power output[29]
  • Mitigates cognitive decline as we age[30]
  • Increases growth hormone levels[31]

The clinically effective dose of alpha-GPC is between 150 and 1,200 milligrams, with 250 to 500 milligrams sufficient for cognitive benefits and higher doses required for affecting dementia.[32]

Stim-free Pulse contains 300 milligrams of AlphaSize® alpha-GPC (standardized to 50%) per serving.

We chose this amount per serving because it’s enough to provide some benefit without eating up too much budget that we’d rather spend on other ingredients.

Furthermore, this dose reduces the likelihood of headaches in people who are using stim-free Pulse and Forge together, and especially in people who are using stim-free Pulse, Forge, and Ascend together.

Betaine

Betaine (also known as trimethylglycine) is an amino acid found in various foods like beets (hence the name), spinach, and quinoa.

Betaine performs two major functions in the body.

  1. It acts as a methyl donor.

  2. It also acts as an osmolyte.

“A what and what?” I can hear you thinking, so let me explain.

Betaine’s rich in a special type of group of carbon and hydrogen molecules known as methyl groups.

These groups can be passed around in the body through a process known as methylation, which is a vital component of many physiological functions, including DNA production, fat metabolism, cellular energy production, and more.

Betaine has a lot of methyl groups to pass around, so it’s known as a “methyl donor.”

Betaine’s also an osmolyte, which is a substance that helps balance fluid levels inside and outside cells.

This is also vitally important because fluid imbalances can cause cells to die either by shrinking too much or swelling to the point of bursting.

Although betaine’s physiological functions aren’t fancy, they’re beneficial during times of physical stress, and this is why research shows that supplementation with it boosts muscle endurance and increases strength.[33][34]

The exact mechanisms of how it accomplishes this aren’t fully understood yet, but several hypotheses are being investigated.

The one currently considered most correct relates to betaine’s “cellular swelling” effect, which helps protect cells from exercise-induced damage and improves performance.[35]

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

Stim-free Pulse contains 2.5 grams of betaine per serving.

No Artificial Sweeteners, Flavoring, Food Dyes, or Unnecessary Fillers

If you compare stim-free 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.[36][37][38][39][40][41]

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.[42][43][44][45]

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.[46][47][48][49][50][51][52][53]

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

Stim-free 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 stim-free 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

Stim-free Pulse is a stimulant-free pre-workout drink that improves mood, sharpens mental focus, increases strength and endurance, and reduces fatigue.

All you have to do is mix a scoop or two with 8 to 10 ounces of water before your workout, swig it down, and wait for the magic.

The beta-alanine and citrulline will give you bigger pumps and more strength and endurance, and the betaine and Alpha-GPC will boost your power and focus.
