Let’s take a look at the formulation.
Many of us can’t shake the cobwebs without our morning cup of coffee, but this powerful compound is a lot more than a mere pick-me-up.
Caffeine helps you lose weight by increasing the amount of energy your body burns throughout the day also improves strength, promotes muscle endurance, and enhances anaerobic performance.
The clinically effective dose of caffeine for enhancing performance is between 3 and 6 milligrams per kilogram of body weight.
Pulse contains 350 milligrams caffeine per serving.
This is the amount of caffeine in one Starbucks grande coffee. Considering the average body weight of most people, it is right in the middle of the clinically effective range for enhancing exercise performance.
L-theanine is an amino acid found primarily in tea that’s responsible for some of its health benefits.
It helps balance the levels of two chemicals in the brain known as neurotransmitters (glutamate and GABA), which transmit nerve impulses.
That’s why research shows that supplementation with L-theanine . . .
Reduces the effects of mental stress
Increases the production of nitric oxide, which improves blood flow
When paired with caffeine, improves mood, memory performance, and attention
The clinically effective dose of L-theanine is between 100 and 250 milligrams, and when combined with caffeine, it’s often found at a 2:1 ratio (twice as much L-theanine as caffeine).
Pulse contains 350 milligrams of L-theanine per serving.
We chose a 1:1 ratio of caffeine and theanine per serving because 2:1 could produce a calming effect, which isn’t desirable before working out.
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.
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.
Additionally, for the purposes of a pre-workout supplement, citrulline malate is superior to L-citrulline for two reasons:
It’s likely that malic acid confers additional health and performance benefits.
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
Relieves muscle soreness
Improves aerobic performance
The clinically effective dose of citrulline malate is between 4 and 10 grams.
Pulse contains 8 grams of citrulline malate per serving.
Beta-alanine is a naturally occurring amino acid that regulates the amount of the molecule carnosine that can be stored in the muscles.
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.
Carnosine counteracts this by reducing muscle acidity, thereby increasing the amount of work the muscles can do before they become fatigued.
As beta-alanine levels in the body rise, so do intramuscular carnosine levels, and this is why research shows that supplementation with beta-alanine . . .
Reduces exercise-induced fatigue
Improves anaerobic exercise capacity
Increases potential workload, which can lead to an increase in lean mass
Reduces feelings of fatigue during exercise
The clinically effective dose of beta-alanine is between 2.6 and 6.4 grams.
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.
Due to the proper dosing of beta-alanine in Pulse, you’re likely to experience this side effect.
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
Mitigates cognitive decline as we age
Increases growth hormone levels
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.
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 Pulse and Forge together, and especially in people who are using Pulse, Forge, and Ascend together.
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.
It acts as a methyl donor.
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.
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.
The clinically effective dose of betaine is between 1.25 and 2.5 grams.
Pulse contains 2.5 grams of betaine per serving.
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.
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.
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.
And while artificial flavors appear to be benign, they just aren’t necessary. Natural flavors taste equally good.
