I Had Epic Workouts On Transparent Labs Bulk Pre-Workout (2024 Review)


Finding a pre-workout that actually works to improve performance is quite tricky. The majority depend on caffeine, which is the primary component producing results. However, Transparent Labs has taken it a notch further by dosing every ingredient according to what has been found effective in research.

Let me show you why this supplement works and how it stacks up to similar products.


  • One of the largest serving sizes to provide the necessary doses for each ingredient to function.
  • A combination of performance and nootropic substances that provide physical and mental benefits.
  • Multiple flavors can satisfy any taste.
  • Banned substances are examined to ensure you do not test positive during a random drug test.
  • Subscription option for price reduction.


  • It is a more costly pre-workout, but the price tag reflects the high quality.
  • There is an underdosing of certain nootropic ingredients.

Transparent Labs Bulk Pre Workout Review

The majority of pre-workout pills contain little more than three to six grams of L-Citrulline. The 8 grams of L-Citrulline in Transparent Labs Bulk Pre-Workout is more than enough to boost your lifting performance right away [1]. So, how does L-Citrulline function exactly?

The famous NO Explode pre-workout aimed to raise blood flow and nitric oxide levels, improving muscle endurance, resistance to fatigue, and recovery time after exercise [1].

While exercising, nitric oxide may reduce oxygen and ATP requirements while increasing the aerobic powerhouse’s ATP production capacity.

By using L-Arginine, which is converted into nitric oxide, NO Explode aimed to increase nitric oxide production.

However, due to poor absorption in the stomach, the evidence does not support the claim that L-Arginine increases nitric oxide activity.

This is why L-Citrulline is a highly effective supplement ingredient.

L-Citrulline is a precursor to L-Arginine, and converting it to L-Arginine solves the kidney absorption problem.

This boosts the concentration of L-Arginine, which converts to nitric oxide and gives the benefits listed above.

You may wonder why Citrulline Malate 2:1 is listed in the ingredients instead of L-Citrulline.

Interestingly, malate works synergistically with citrulline, perhaps increasing ATP synthesis, lowering lactic acid, and extending weariness. It is great for those looking to increase their reps in the gym.

Taking 8 g of Citrulline Malate 60 minutes before exercise increases repetitions to failure in both the upper and lower body, reduces muscular soreness 24 and 48 hours later, and improves maximal grip strength [1].

For those interested in endurance, ingesting 6g of Citrulline Malate daily for seven days shortens the time to exhaustion during moderate-intensity cycling [2].

Doses as low as 2.4g per day for seven days increased the time to completion and power output when cycling 4 kilometers.

Furthermore, compared to a placebo, sensations of muscle fatigue improved after exercise [3].

If you want to up the 8 g dose, couple your Transparent Labs Bulk Pre-Workout with fresh watermelon or juice. Watermelon is a natural source of L-Citrulline, with 0.7-3.6 mg per gram of fresh weight.

Beta-Alanine (4000 mg)

The next active component is beta-alanine, which is included in a dose of 4 g per serving.

Acute performance effects are noticeable at doses of 30 mg per kilogram of body weight 60 minutes before exercise, making this Transparent Labs Bulk Pre-Workout perfect for most people, as you’d have to weigh more than 130 kg to miss this dose.

Beta-alanine prolongs the time you can exercise at high intensity for 1-4 minutes [4][5].

For example, if you were running an 800m race, you could maintain a higher intensity throughout the race, improving your 800m performance.

How does it do this? Beta-alanine causes a rise in carnosine levels. During high-intensity exercise, carnosine either buffers or removes hydrogen ions accumulating in the muscle.

The hydrogen ions in the muscle produce an acidic environment. An acidic muscular environment causes fatigue because it reduces the muscle’s ability to contract.

By buffering or removing these hydrogen ions, the muscle’s pH remains neutral for longer, hence extending fatigue.

Citrulline Malate and Beta-Alanine work together to allow you to accomplish many more reps in the gym, resulting in enhanced muscular growth.

A recent systematic review of beta-alanine supplementation in combat sports discovered that athletes enhanced their strength, power, total work capacity, perception of recovery from physical exertion, lean mass, and fat mass [6].To develop endurance, aim for 179 g over 3-10 weeks [7].

Betaine Anhydrous (2500 mg)

Transparent Labs Bulk Preworkout

Transparent Labs Bulk has a third active component, betaine. In a fasting condition, consuming two doses of betaine per day of 1.25 g (2.5 g total) with a sports drink increased bench press reps by 6.5% while decreasing lactate (and thereby hydrogen ions) levels [8].

The same quantity may reduce AMPK pathway participation following exercise, enhancing the anabolic (muscle development) environment [9].

During endurance exercise, the AMPK pathway is activated. It inhibits the mTOR pathway, which is important for muscle growth.

By lowering the involvement of the AMPK system, the mTOR pathway can be activated for longer periods, potentially leading to increased muscle growth.

Taurine (1300 mg)

Caffeine and taurine are best friends. The more taurine you consume, the less caffeine you need for performance benefits, and higher taurine doses equal better performance [10].

Furthermore, a single dose of 1-6 g before exercise can improve endurance performance independent of dose size [11].

L-Tyrosine (1000 mg)

As supplement companies seek a competitive advantage, nootropic substances have increasingly found their way into pre-workout formulations.

Nootropics are essentially brain vitamins. Improving your cognitive function is also known as enhancing your mental performance. This is likely why Transparent Labs incorporated L-Tyrosine.

The dietary amino acid L-tyrosine has been found to boost dopamine levels in the brain.

L-tyrosine supplementation has been shown to improve cognitive regulation in trials, especially in intellectually challenging settings [12].

It is notably helpful for increasing cognitive flexibility, which is influenced by dopamine.

While L-Tyrosine’s potential for treating clinical disorders and enhancing physical activity is limited, it can be beneficial under stressful or cognitively demanding circumstances.

It provides the greatest cognitive benefits when neurotransmitter activity is normal, but dopamine and norepinephrine levels are temporarily reduced [13].

According to studies, the best dose for cognitive improvement begins at 2 grams.

Unfortunately, Bulk includes only 1 g each serving, which could reduce its effectiveness.

Alpha GPC (300 mg)

The choline-containing phospholipid alpha GPC improves cognitive function in neurological conditions like dementia [14].

According to studies, it increases memory and concentration, which may benefit brain health.

Clinical studies have indicated it can improve cognitive performance, especially with other treatments like donepezil [15].

It is generally safe and well tolerated. The amino acid alpha GPC increases the brain’s acetylcholine levels, which are required for memory and learning [16].

It is used as both a medicine and a nutritional supplement. Alpha GPC enhances cognitive performance, particularly in cases of adult-onset dementia [17].

However, 200 mg of Alpha GPC may improve vertical jump performance comparably to coffee [18].

Organic Caffeine (200 mg)

Transparent Labs Bulk vs Bulk Black

Caffeine is a powerful substance that boosts power and sprint performance by 6.5% and increases the number of reps performed when lifting by 9.4% [19].

It also improves endurance performance by 2.22% in time trials and 2.9% in power output compared to a placebo [20].

Caffeine doses vary between 3 and 6 mg per kilogram of body weight, with every dosage in this range increasing performance.

Lower caffeine levels of <3 Mg/kg body mass (about 200 mg) found in Transparent Labs Bulk may be effective for some people [21][22].

L-Theanine (200 mg)

L-Theanine has a reputation for boosting mental health, with studies demonstrating that daily doses of 200-400 mg help reduce stress and anxiety [23][24].

The caffeine L-theanine stack improves both physical and cognitive function.

Some benefits include faster reaction time, faster visual processing speed, improved working memory, enhanced awareness, and reduced exhaustion and mental fatigue [25][26].

The trials use a 2:1 L-theanine to caffeine ratio. Transparent Labs Bulk uses a 1:1 ratio. In my experience, utilizing any ratio works equally well.

Theobromine (50 mg)

Theobromine, a cocoa component, has been studied for its possible cognitive benefits.

According to studies, theobromine may have a slower nootropic effect than coffee, but it may provide neuroprotective benefits over time, potentially decreasing Alzheimer’s disease-related pathology [27].

More research is needed to understand its effects on cognition fully.

Theobromine appears to have different effects on mood and vigilance than coffee, with some studies indicating it may not significantly influence these traits in nutritionally relevant quantities [28].

However, combining theobromine with coffee may change its effects, potentially delivering cognitive and mood benefits while not dramatically increasing blood pressure [29].

More research is needed to confirm theobromine’s cognitive and mood-altering effects.

Transparent Labs Bulk contains 50 milligrams of theobromine. However, doses higher than 400 mg are required to improve cognition.

Panax Ginseng (50 mg)

Transparent Labs Bulk vs Lean

Panax ginseng is available in white and red varieties. It has vasodilatory and mildly hypotensive effects on nitric oxide production in the body [30].

It boosts antioxidant enzyme activity and may protect rats against oxidative damage caused by aging [31].

Ginseng has shown potential in memory enhancement, notably in age-related cognitive decline, as well as enhancing mental and physical resilience, tiredness reduction, and stress adaptation [32].

A daily 200 mg extract or 0.5 to 2 g dry root intake is advised. It is not recommended for people with acute asthma or hypertension since it might cause overstimulation and raise blood pressure at high doses.

Transparent Labs Bulk contains a 50 mg dose, which may not deliver the same mental performance benefits.

Bioperine (5 mg)

BioPerine is a patented and trademarked chemical claiming to increase nutritional absorption [33]. It’s debatable whether there is a significant effect.

Boron (3000 mcg)

Boron, a trace element not currently deemed essential for humans, has been found to affect brain function and cognitive performance.

According to research, insufficient boron consumption may result in decreased brain electrical activity, as seen in general malnutrition or heavy metal toxicity [34].

Low boron levels have also been linked to poor performance in tasks requiring manual dexterity, eye-hand coordination, attention, perception, and memory [35].

Transparent Labs is considerably below the research-defined high boron consumption of 3.25 mg boron/2000 kcal/day.

These results suggest boron may benefit brain health and cognitive capacity.

Transparent Labs Bulk Price

Transparent Labs Bulk is a premium pre-workout supplement, and the pricing reflects this. A one-time purchase costs $49.99, which equates to $1.67 per serving. With a subscription, you save $5, including free shipping, bringing the price per serving down to $1.50.

Transparent Labs Features

Transparent Labs Bulk Pre Workout Benefits

Taste And Mixability

You can choose from 12 different flavors. I tried the peach mango flavor, and like with all Transparent Labs products, the flavors are distinct and powerful.

For example, most supplement firms provide a blue raspberry-flavored product with a stock taste.

Transparent Lab’s flavors taste slightly different, which could be owing to specific flavor creation. In terms of mixability, it blends easily with no lumps, similar to how most modern pre-workouts are mixed in shaker bottles.

Third-Party Testing

Third-party testing has two purposes:

To test for contaminants and heavy metals that could harm your health and to find potential banned substances that could cause a failed drug test at a sporting competition.

You should be interested in testing for toxins in a sector unregulated by the FDA since only 8% of supplements on Amazon are tested [36].

If you are a competitive athlete, always search for the informed sport tick, which Transparent Labs Bulk has, indicating the product is free of banned substances.

What’s The Difference Between Bulk And Bulk Black?

The only difference between Bulk and Bulk Black is the 300 mg of caffeine in Bulk Black, whereas Bulk has 200 mg. All other components and dosages are the same.

Transparent Labs Bulk vs. Lean

Transparent Labs Lean has a lesser dose of the same components as Bulk (with some removed), as well as L-carnitine, choline bitartrate, and Huperzine A. Lean also contains 20 mg less caffeine than Bulk.

Transparent Laboratories Lean was created to help you lose fat. However, the extra substances are only speculative in aiding fat reduction.

Who Is Transparent Labs Bulk Pre-Workout For?

Athletes Seeking Enhanced Performance

Bulk Pre-Workout is great for athletes looking to increase their strength, endurance, and overall athletic performance.

Because it is free of banned substances, you do not need to be concerned about popping on competition drug tests from contaminated supplements.

It’s appropriate for fitness enthusiasts who need an extra energy boost for their workouts, assisting in increasing focus and drive throughout exercise sessions.

My Experience With Transparent Labs Bulk Pre-Workout

Is Transparent Labs Bulk Pre Workout Good

This supplement is the bomb.

Combined with the other pump components, the 200 mg of caffeine ensures you will power through even the most strenuous workouts. I felt amazing during my regular training routine after taking Transparent Labs Bulk.

I will warn you this pre-workout is not for you if the tingling sensation of beta-alanine is something you find unpleasant.

This pre-workout supplement contains 4 grams of beta-alanine, which is the highest single amount I am aware of.

Because the tingles are so powerful, it will literally knock your socks off. This is why taking beta-alanine in smaller dosages throughout the day is usually best.

The tingles, nevertheless, are often associated with the “working” of pre-workout supplements, so those who enjoy them will likely also enjoy this supplement.

User Reviews & Testimonials

The user reviews on the company’s website strongly support the notion you should buy this supplement if you are serious about your workouts. The Bulk pre-workout has over 4300 reviews totaling a score of 4.7/5.0. Here are a few of the reviews:
