CHECK IT OUT 

If you're on the hunt for a pre-workout supplement that packs a punch, you may have seen Transparent Labs Bulk Black.

This pre-workout has been one of the breakthroughs for Transparent Labs because they don't usually make this type of pre-workout. 

(See Is Transparent Labs Legit?)

They normally have their pre-workouts a little more moderate with the energy. 

For example, Bulk and Lean both have around 220mg of caffeine along with theanine. 

But Bulk Black takes it up to the next level. 

This pre-workout has around 300mg of caffeine, coming from multiple sources. 

First, we'll dive into my review then we'll break down the label and the FAQ's about this pre-workout...

My Bulk Black Experience

The original Bulk has always been my trusty pre-workout for those days when I want to take a breather from the stimulant roller coaster, yet still need that gentle caffeine nudge to power through my workouts.

It's like a whisper in the ear, just enough to keep you moving without fearing a caffeine-induced frenzy.

But then, there's Bulk Black.

This pre-workout is a whole different beast.

It doesn't just whisper; it takes things to the next.

The energy surge hits hard within minutes, and it's fast.

I can feel it coursing through your veins almost instantly after I take a sip.

Packing a solid 300mg of caffeine stands out in the Transparent Labs lineup.

It's like the family's big brother, flexing its muscles and showing off its strength.

But here's the twist:

Despite the hard-hitting energy, there's no crash.

It's like riding a high-speed train that slows smoothly as it approaches the station.

If you're all about the pump, Bulk Black might leave you wanting more.

The pump effects are decent, not extraordinary, but they do the job.

It increases blood flow and all that, nothing crazy, but it's enough to keep you going.

The show's real star with Bulk Black, though, isn't just its formula.

It's the clean, natural sweetness.

It's like sipping on a refreshing, guilt-free elixir that also happens to supercharge your workout.

It's a clean experience from start to finish.

Transparent Labs BULK Black is a unique blend that's as clean as it gets.

Sweetened with stevia, it skips the sugars and carbs, making it a calorie-free companion for your workouts.

And if you're wondering about protein or fat, there's none of that either.

The formula is a powerhouse of 17 ingredients, kicking off with five inactive vitamins and minerals.

You've got your Vitamins D, B6, and B12, along with sodium and potassium - essential electrolytes that keep your body in balance.

But the real stars of the show are the 12 active ingredients.

We're talking citrulline malate, beta-alanine, betaine anhydrous, taurine, L-tyrosine, AlphaSize Alpha-GPC, caffeine anhydrous, L-theanine, theobromine, Astragin, Infinergy di-caffeine malate, and boron.

These are the game-changers, the ones that deliver the physical and mental benefits you can feel.

Citrulline

Citrulline malate is a combination of the amino acid citrulline and malate, an apple derivative.

It's known for its ability to increase nitric oxide production, which can improve blood flow, delay muscle fatigue, and enhance strength and aerobic performance [1, 2, 3, 4

Citrulline is also found in some foods, like watermelon.

In the body, citrulline plays a key role in the urea cycle, which is a process that helps your body eliminate harmful nitrogen waste substances. [5

In terms of its properties, citrulline is known for its ability to increase nitric oxide production in the body.

Nitric oxide is a gas that expands blood vessels and improves blood flow. 

By boosting nitric oxide production, citrulline can enhance exercise performance, reduce muscle soreness, and speed up recovery time [6, 7].

In addition to its performance-enhancing benefits, citrulline also has several other potential health benefits.

It may improve heart health, boost immune function, and even have potential benefits for people with diabetes and erectile dysfunction.

In Bulk Black, citrulline is combined with malate to form citrulline malate.

This combination is believed to enhance the production of nitric oxide even further, leading to even greater performance benefits.

Beta-Alanine (4g)

Beta-alanine is an amino acid that's used by your body to produce carnosine, a substance that helps muscle endurance during high-intensity exercise. [8, 9]

It can delay muscular fatigue, increase overall muscle strength, and improve muscle endurance. [10, 11, 12]

It's a non-essential amino acid that plays a crucial role in muscle endurance during high-intensity exercise.

Unlike other amino acids, it's not used by our bodies to synthesize proteins.

Instead, it helps to produce carnosine, a molecule that buffers acid in muscles, thus delaying the onset of muscle fatigue and allowing for increased performance and physical capacity.

During periods of strenuous exercise, lactic acid builds up in the muscles, leading to an acidic environment that can cause muscle fatigue and hinder performance.

Beta-Alanine counteracts this by increasing carnosine concentrations in the muscles, which then helps buffer the acid, reduce muscle fatigue, and enhance athletic performance.

While Beta-Alanine is generally safe for consumption, it's worth noting that it may cause a harmless side effect known as paresthesia, a tingling sensation on the skin.

This sensation is temporary and usually subsides within an hour of consumption.

In conclusion, Beta-Alanine is a valuable supplement for athletes and fitness enthusiasts looking to enhance their performance and push their physical limits.

Its ability to buffer muscle acid and delay fatigue can be a game-changer in high-intensity workouts.

Now, you might be wondering, "Is this stuff safe?".

The answer is yes.

In fact, a bunch of studies, like ones published in the Journal of the International Society of Sports Nutrition and Frontiers in Physiology, have shown that Beta-Alanine can be a real game-changer for athletic performance, especially during high-intensity, short-duration exercises.

But here's a heads up: Beta-Alanine might cause a tingling sensation on the skin.

It's totally harmless and usually goes away within an hour.

It's just Beta-Alanine's way of saying "Hello, I'm here!", or a way for you to feel like Spider-Man.

BetaPure Betaine Anhydrous (2.5g) 

Betaine, or trimethylglycine (TMG), is a potent ergogenic aid.

A daily dose of 2.5 grams can boost physical performance, including power and endurance. [13]

Betaine acts as a methyl donor, aiding in metabolic processes and optimizing energy production. [14]

It also helps balance homocysteine levels, reducing cardiovascular disease risk. [15]

Additionally, Betaine is an osmolyte, enhancing cell hydration and nutrient access, and protecting against metabolic stress. [16]

Research shows betaine supplementation can improve strength, power, and body composition. [17]

A 2013 study found that a daily dose of 2,500 milligrams led to significant muscle gain and fat loss over one and a half months.

Here's an overview of the benefits that betaine offers:

  • Betaine, also known as trimethylglycine (TMG), enhances physical performance.
  • Betaine acts as a methyl donor, aiding in metabolic processes and energy production.
  • Betaine helps balance homocysteine levels, reducing cardiovascular disease risk.
  • As an osmolyte, it enhances cell hydration and nutrient access.
  • Research shows betaine supplementation can improve strength, power, and body composition.

So really, Betaine is a valuable supplement for overall health and physical performance enhancement.

Taurine (1.3g)

Taurine is a versatile supplement ingredient, offering benefits from improved hydration to enhanced mitochondrial efficiency, dopamine upregulation, and body fat browning. 

Like betaine, taurine is an osmolyte, capable of inducing cellular hyperhydration. [1819]

This process enhances cellular-metabolic efficiency and resilience to heat stress.

A single 1,000-milligram dose of taurine, taken before exercise, can significantly boost athletic endurance.

Taurine also functions as a powerful antioxidant and supports calcium signaling in muscle tissue, optimizing athletic performance and preventing cramps. [20, 21]

In the brain, taurine mimics a neurotransmitter called gamma-aminobutyric acid (GABA), which has calming and anti-inflammatory effects on neurons. [22]

It also promotes mitochondrial biogenesis in the brain, enhancing energy production for brain cells.

Furthermore, taurine can upregulate dopamine production and signaling, aiding focus and motivation during workouts.

Taurine also aids in fat loss and muscle building.

It can increase the body's proportion of brown adipose tissue (BAT), a type of fat tissue rich in mitochondria.

Taurine induces the browning of fat, converting white adipose tissue (WAT) into BAT.

This process increases caloric burn through non-shivering thermogenesis (NST).

Taurine can also inhibit the growth of new WAT cells while promoting the formation of new BAT.

This can improve blood lipids and blood glucose, mitigating some harmful effects associated with excess body fat.

Given that taurine is conditionally essential, with metabolic requirements increasing with workout intensity, gym enthusiasts can benefit from taurine supplementation.

The dose in Bulk Black is 1.3g, around the standard for minimum dosing, offering more benefits as taurine effects are dose-dependent.

Tyrosine (1g)

Tyrosine is a standout pre-workout ingredient for two main reasons:

Firstly, tyrosine is a precursor to crucial neurotransmitters like dopamine, adrenaline, and noradrenaline.

Supplementing with tyrosine can enhance focus, motivation, and energy, while also boosting your body's fat-burning rate.

Secondly, tyrosine supports thyroid function. [23, 24]

It's a precursor to the body's primary thyroid hormones, triiodothyronine (T3) and thyroxine (T4). [25]

This is particularly beneficial for gym enthusiasts, as intense dieting and strenuous exercise can stress the thyroid, leading to an imbalance in stress and thyroid hormones.

An additional benefit of tyrosine, particularly for those experiencing sleep deprivation, is its ability to restore cognitive function.

In fact, research suggests that tyrosine is more effective than caffeine at improving cognitive function during periods of sleep deprivation.

AlphaSize Alpha-GPC (300mg)

Alpha-GPC, or Alpha-glycerophosphocholine, is a phospholipid rich in choline, an essential nutrient that aids in maintaining cell membranes and is crucial for synthesizing acetylcholine, a neurotransmitter that regulates brain function and muscle control. [26, 27]

Alpha-GPC enhances the processing of acetylcholine in the body, ensuring optimal choline yield. [28]

Alpha-GPC is superior to other forms of choline like choline citrate or choline bitartrate in boosting acetylcholine production.

Its lipid content makes it easier for cells to absorb, thus more effectively increasing acetylcholine production.

This makes Alpha-GPC a more beneficial form of choline.

There's a reason why we keep saying this can help enhance the mind-to-muscle connection:

Alpha-GPC can enhance the "mind-muscle connection," a focus on muscle contractions during exercise that has been shown to yield better results.

It increases acetylcholine levels in the frontal cortex of the brain, which controls motor function and attention management.

This could lead to improved focus and a better mind-muscle connection during workouts.

Alpha-GPC also has potential strength-boosting and growth hormone-raising effects.

Studies have shown that it can increase strength and power in resistance training. A dose of 600mg of Alpha-GPC resulted in a larger increase in peak growth hormone and a 14% increase in bench press force.

Another study showed that Alpha-GPC increased force in mid-thigh pulls, suggesting it can boost lower body force production.

Interestingly, lower doses of Alpha-GPC have also been found effective.

A study comparing different dosages found that a 250mg dose resulted in significantly greater power in a jump test and a 132% increase in serum choline.

This suggests that lower doses of Alpha-GPC may still be effective and possibly even preferred.

L-Theanine (200mg)

Does 300 milligrams of caffeine seem a bit much?

Don't worry, theanine is here to smooth things out.

L-theanine, a natural amino acid found in the Camellia sinensis plant, the source of white, green, oolong, and black teas, has a calming effect on the brain.

Acting as a neurotransmitter, it reduces anxiety by inhibiting neurotransmission without causing sedation.

The magic happens when theanine and caffeine come together.

This dynamic duo enhances mood and cognition, outperforming the effects of either ingredient alone.

They work in tandem to improve mental accuracy, reduce fatigue, speed up reaction times, and boost numerical working memory. [29, 30]

They also enhance the ability to judge written texts and increase alertness.

Theanine is particularly beneficial for stressed individuals, increasing attention and reducing reaction time. [31]

It's also known to improve sleep quality and reduce resting heart rate by upregulating GABA, a calming neurotransmitter that inhibits neurotransmission. [32]

And if you're looking to reduce cortisol, Transparent Labs Vitality is a great choice.

It contains KSM-66 (ashwagandha), known for its cortisol-reducing properties.

Caffeine Anhydrous (275mg)

Caffeine, the world's most popular legal stimulant, is consumed daily by a vast majority of American adults.

Its ability to stave off fatigue makes it a go-to for those with busy schedules. 

What sets caffeine apart is its ability to cross the blood-brain barrier, a feat most nutritional supplements can't achieve. [33]

This unique capability allows caffeine to significantly influence the central nervous system. [34]

Like its close relative, theobromine, which is also present in Bulk Black, caffeine works by blocking the action of adenosine.

Adenosine is a nucleotide that accumulates in the brain during wakefulness, gradually increasing mental fatigue.

Fatigue is a common issue for those trying to lose weight, as calorie restriction can significantly reduce energy levels. [35, 36]

This is why dieters often consume large amounts of tea or coffee.

It's also why caffeine is a favored ingredient in fat-burning supplements.

Caffeine can also inhibit phosphodiesterase, an enzyme that breaks down cyclic adenosine monophosphate (cAMP), a messenger molecule that signals cells to burn more glucose and fatty acids for energy.

By inhibiting phosphodiesterase, caffeine raises cAMP levels, which in turn speeds up your metabolism, leading to more calories burned throughout the day.

What's more, caffeine is particularly effective at accelerating fat burning.

Animal studies have found that caffeine supplementation can increase the body's rate of fat-burning by up to 50%.

So, not only does caffeine keep you alert, but it also helps you burn fat more efficiently.

Theobromine (50mg)

Theobromine, like caffeine, belongs to the methylxanthine class and has stimulant, bronchodilatory, and vasodilatory effects.

It works similarly to caffeine by inhibiting phosphodiesterase, leading to increased cyclic adenosine monophosphate (cAMP) levels. [37]

This results in increased caloric expenditure by boosting mitochondrial function and cellular energy production.

However, theobromine differs from caffeine in its primary target.

While caffeine primarily stimulates the central nervous system, theobromine focuses on relaxing smooth muscle, which lines the inside of blood vessels.

This means theobromine can reduce blood pressure, unlike caffeine, which is known to increase it.

Interestingly, combining theobromine with caffeine can counteract caffeine's effect on blood pressure, making this a smart ingredient pairing.

You get the benefits of caffeine with less of the downside.

Additionally, theobromine can support cardiovascular health by optimizing nitric oxide production and function. [38]

Infinergy (Dicaffeine Malate) (30mg)

Infinergy, also known as dicaffeine malate, is the third source of caffeine in our mix.

It's essentially caffeine molecules bound to malic acid, which slows down the caffeine's activation time.

This process results in a longer-lasting energy curve and less of a crash.

You still get the stimulant properties of caffeine, but the ride is much smoother, especially when paired with theanine.

Dicaffeine malate is about 73-75% caffeine by mass, yielding approximately 75mg of actual caffeine per serving.

It's a longer-acting form of caffeine compared to caffeine anhydrous due to the chemical binding of the caffeine molecule to malic acid, which delays digestion and absorption.

This slower rise in caffeine blood levels and lower peak level means a less harsh comedown.

Stacking malate with anhydrous gives you a quick energy boost with extended action and a gentler withdrawal.

Aside from the difference in timing, di-caffeine malate provides the usual effects of caffeine.

This adds about 25 milligrams more actual caffeine, bringing our total to aroudn 300 milligrams, not counting the 50mg of thebromine.

Astragin (50mg)

AstraGin works by enhancing the production of adenosine triphosphate (ATP) in intestinal cells, providing them with more energy to function effectively. [39]

This increased energy allows your intestinal cells to absorb more nutrients from the food and supplements you consume, thereby boosting their bioavailability. [40]

AstraGin is becoming increasingly popular in supplement formulations due to its ability to maximize the value of the product for the consumer.

Its effectiveness and benefits have been demonstrated in over 20 published research studies.
