Things to Consider Before Buying Transparent Labs Bulk Pre-Workout

Let’s go over some key points to help determine if Transparent Labs Preseries Bulk is right for you. 

Caffeine/Stimulants

Transparent Labs Bulk has 180mg of caffeine as well as 30mg of dicaffeine malate and some other stimulants. 

So, this can be a good or bad thing depending on if you want stimulants in your pre-workout or not. 

You also want to be mindful to not consume Bulk too late in the day, even if you do want caffeine in it.

Dosages

After quickly scanning the ingredients, it seems that Bulk has high doses for most of its ingredients (we’ll get into this more later). 

Therefore, it might be better for more experienced pre-workout users since they’re more likely to know how ingredients affect them. 

If you’re new to pre-workouts, you may want to start with a lower dose of this one.

Price

Transparent Labs Preseries Bulk is priced pretty high at $1.67 per serving. This isn’t a great option for people who want a highly affordable pre-workout. 

Free From Anything Artificial

Lastly, if artificial sweeteners, flavors, preservatives, and related ingredients are turn-offs for you, you don’t have to worry about Bulk. It doesn’t contain anything artificial. 

Transparent Labs Bulk Pre-Workout Features

Bulk Pre-Workout has a few different features that stand out. Take a look below for some of the top features of Preseries Bulk by Transparent Labs. 

Targeted Anabolic Micronutrients

One factor in muscle growth that’s sometimes overlooked is hormonal status. Yet, if you’re anabolic hormones aren’t at optimal levels, you just won’t grow as well. 

Fortunately, Transparent Labs Bulk Pre-Workout is said to contain targeted micronutrients to support testosterone and anabolic hormone production. They have vitamin D3, zinc, and boron, to name a few. 

Key Nootropics Delivery

Have you ever lost motivation during a workout? Or how about feeling a lack of focus and drive?

Well, Transparent Labs Preseries Bulk is advertised to eliminate all that with the inclusion of key nootropics. 

They have taurine, Alpha-GPC, theanine, and caffeine to help get your brain dialed in and firing on all cylinders.

Enhanced Strength, Stamina, and Muscle Pumps

When most people are buying a pre-workout, they want one that hits all aspects of their training sessions. 

Bulk is made with a wide variety of ingredients to enhance strength, stamina, and muscle pumps. It is really made to be an all-in-one pre-workout, or what I like to call the “Total Package”. 

Muscle Growth

With a fair amount of pre-workouts, sometimes you can feel like they are working only to find out that you’re not gaining any muscle. And this can be due to suboptimal ingredients. 

Fortunately, Bulk Pre Workout claims to include only the best pre-workout ingredients to help you pack on lean muscle. In fact, that’s the very reason this supplement is called “Bulk”. 

Nothing Artificial

A lot of pre-workouts on the market are filled with artificial colors, flavors, sweeteners, and other synthetics. 

Transparent Labs Bulk Pre Workout is free from all of that, so you can have peace of mind and give the body things it recognizes. 

Does Transparent Labs Bulk Pre-Workout really work?

Overall, I really like what I see from Transparent Labs Bulk Pre-Workout. This supplement is likely to be effective for most people. 

Of course, individual results vary, and ingredients affect everyone a little differently. 

The wide variety of ergogenic ingredients in it should make it effective for enhancing strength, focus, endurance, pumps, and more. 

So, keep reading my Transparent Labs Bulk Pre Workout review to see how it may benefit you. 

Transparent Labs Bulk Pre Workout Ingredients

Below is a list of Transparent Labs Bulk ingredients and a snapshot of how they may work. 

Transparent Labs Preseries Bulk contains the following active ingredients:

• Citrulline Malate
• Beta-Alanine
• Branched-Chain Amino Acids (BCAAs)
• Betaine
• Vitamin D3, Zinc, and Boron
• Caffeine
• Taurine
• Tyrosine
• Theanine
• AlphaSize® Alpha GPC
• Theobromine
• Infinergy™
• Astragin
• Vitamin B6
• Vitamin B12
• Sodium and Potassium

Citrulline Malate (6,000mg)

Citrulline malate is a combination of the amino acid, L-citrulline, and malic acid. 

Citrulline can increase arginine and nitric oxide levels. This can ultimately increase oxygen and blood flow to the muscles. 

Plus, the malic acid component may help to increase energy and delay fatigue. 

Together, citrulline malate supplementation has been proven to be effective for endurance and even recovery. 

Effective dosage according to Examine: 8g, but up to 15g in some cases. 

Beta-Alanine (4,000mg)

Beta-alanine is an amino acid that can increase muscle carnosine concentrations. This can be beneficial due to carnosine’s role in exercise, particularly as a lactic acid buffer. 

Overall, beta-alanine seems to be beneficial for reducing fatigue and improving performance, especially in short-duration, high-intensity exercise. 

Estimated effective dosage: 3.2 to 6.4g

Branched-Chain Amino Acids (BCAAs) (4,000mg) 

Bulk also has BCAAs in a 2:1:1 ratio of leucine, isoleucine, and valine. 

Of these, leucine seems to be the most beneficial because it has a key role in muscle protein synthesis. 

However, isoleucine and valine may play roles in muscle protein synthesis, too. Isoleucine also increases glucose uptake into cells. 

BCAAs may be able to reduce physical and mental fatigue during long bouts of exercise. And they may help reduce post-workout soreness but are not necessarily beneficial for enhanced muscle growth. 

Effective dosage: 20g with a 2:1:1 ratio mentioned above

Betaine (2,500mg)

Up next is betaine, an amino acid known for its presence in beetroot. 

Betaine is an osmolyte, and it can help increase cellular hydration which may benefit performance. 

Plus, betaine has been shown to increase muscle protein and creatine synthesis, and might also reduce lactic acid build-up during exercise. 

Overall, betaine seems most effective for enhancing lean body mass but not necessarily increasing workout performance.

Effective dosage according to Examine: 2.5g

Vitamin D3 (75mcg) Zinc (30mg), and Boron (3mg)

Up next are three different ingredients which Transparent Labs calls the “Targeted Micronutrients” for anabolic hormone support. 

And indeed, research shows the benefits of these micronutrients for testosterone and anabolic hormones. 

Specifically, research has shown associations between low vitamin D, zinc, and boron levels and low testosterone. Higher levels of these micronutrients are related to higher testosterone levels. 

Vitamin D plays a key role in testicular production of testosterone, although supplementation doesn’t always directly increase it. But vitamin D also plays key roles in bone and muscle health, which might make it beneficial for athletes. 

Also, supplementation with zinc and boron appears to be more beneficial for increasing total and free testosterone. These minerals have antioxidant effects and decrease SHBG and estrogen, which can free up testosterone. 

• Effective dose of vitamin D3: 1,000 to 2,000 IU
• Effective dose of zinc: 25 to 45mg
• Effective dose of boron: At least 3mg

Caffeine (180mg)

Bulk has a decent dose of caffeine in the form of caffeine anhydrous. 

This “wonder drug” is a potent stimulant that fires up various neurotransmitters in the central nervous system, such as dopamine, serotonin, and noradrenaline. 

Taking a high dose of caffeine has been shown to increase strength, endurance, and power while reducing fatigue and even pain perception. 

Cognitively, caffeine can also increase alertness, focus, and mood, especially when taken with theanine (listed below). 

Effective dosage according to numerous studies: 3 to 6mg/kg (or about 200 to 500mg for most people)

Taurine (1,300mg)

Taurine is an amino acid that has antioxidant and anti-inflammatory effects. Plus, it plays key roles in energy metabolism and cognitive function. 

Current research suggests that taurine supplementation can increase endurance, reduce fatigue, improve strength and power, and decrease recovery time. 

Effective dosage according to the Journal of the International Society of Sports Nutrition: 1 to 3g

Tyrosine (1,000mg)

Tyrosine is an amino acid that is a precursor to dopamine and norepinephrine. Those neurotransmitters are involved in mood, arousal, and cognition, yet they can be depleted during stressful exercise. 

Fortunately, tyrosine supplementation may benefit cognitive performance when under stress by replenishing those neurotransmitters.

Effective dosage according to Examine: 100 to 150mg/kg, which is around 7 to 13.5g for most people (but lower doses [500 to 2,000mg] have been used anecdotally with success, too). 

Theanine (360mg)

Theanine is an amino acid found in green tea leaves. Theanine can increase GABA and alpha waves in the brain, which reduces stress and produces a calm, focused state. 

And there is evidence that theanine can improve attention, alertness, reaction time, and overall cognitive function. Plus, its effects are better when combined with caffeine, especially with a 2:1 ratio.

Effective dosage: Usually 100 to 200mg, sometimes higher

AlphaSize® Alpha GPC (300mg)

AlphaSize® is a trademarked form of alpha GPC, which is a choline compound. Supplementing with alpha-GPC can increase acetylcholine, a neurotransmitter involved in cognitive functions but also muscular force and physical performance. 

Some research shows that Alpha-GPC can increase strength and power, while even boosting growth hormone. But not all studies are conclusive.

Effective dosage based on research: 300 to 600 mg

Theobromine (50mg)

Theobromine is a milder stimulant found in cocoa and other plants. Limited evidence shows that theobromine may increase endurance and other aspects of exercise performance. 

More research is needed to see if it can reduce fatigue. 

Effective dosage according to Drug Testing Analysis Journal: 300 to 600 mg

Infinergy™(30mg)

Infinergy™ is a trademarked form of dicaffeine malate. This form of caffeine is said to be more bioavailable and longer-lasting. More research is needed to determine its effects. 

Effective dosage: N/A

AstraGin™ (25mg)

AstraGin™ is a trademarked combination of astragalus root and Asian ginseng extracts. It is included to increase the bioavailability of the other ingredients, which may lead to greater benefits.

Recommended dosage according to EFSA Journal: 0.5mg/kg of body weight

Vitamin B6 (5mg)

Vitamin B6 is a B-complex vitamin involved in energy metabolism and brain health. Exercise may increase the need for vitamin B6, but it’s unclear if supplementation is directly beneficial. 

Effective dosage: N/A

Vitamin B12 (100mcg)

Vitamin B12 is another B-complex vitamin involved in energy metabolism and brain health. It’s particularly important for cognitive function and mood, too. 

Yet, it’s unclear if vitamin B12 supplementation will deliver any exercise benefits. 

Effective dosage: N/A

Sodium (150mg) and Potassium (100mg)

The final two ingredients in Bulk are sodium and potassium, which are electrolytes. Electrolytes help to maintain cellular hydration during exercise. 

Plus, they may be able to maintain muscle contractions and reduce the risk of cramping and headaches. 

Going too low in electrolytes can reduce performance and potentially harm one’s health. But supplementation seems only effective in highly intense exercise and/or in hot environments. 

Effective dosage: Unclear

Available Flavors

Transparent Labs Bulk Pre Workout is available in 10 different fruity flavors. The flavors are:

• Sour Grape
• Watermelon
• Green Apple 
• Orange
• Blue Raspberry
• Strawberry Lemonade
• Tropical Punch
• Lemon Lime
• Black Cherry
• Peach Mango

Transparent Labs Bulk Pre Workout Pros and Cons

Another important part of this Transparent Labs Bulk Pre-Workout review is analyzing the pros and cons. 

Overall, Transparent Labs Preseries Bulk has more pros than cons and should be pretty effective. Here are some major factors to consider:

Pros

• A lot of well-researched ingredients
• Clinically effective doses for most ingredients
• Includes caffeine and stimulants for energy
• May improve strength, pumps, endurance, and power
• Includes nootropics for focus and drive
• No artificial flavors, colors, or sweeteners
• Compliant with FDA GMP standards

Cons

• Pretty expensive
• A couple of ingredients are underdosed
• BCAAs underdosed

How to Use Transparent Labs Bulk Pre Workout

It is recommended to take PreSeries Bulk 20 to 30 minutes before your workout. 

Recommended Dosage

Initially, you are recommended to take just a half scoop with 8 to 12 ounces of water to assess tolerance. 

The most effective dosage is one scoop mixed with 16 to 24 ounces of water. So, take one scoop if you tolerate a half scoop with no issues. 

Stacking a Pump Pre-Workout (Stim-Free)

You may also want to consider stacking Transparent Labs Bulk with a pump pre workout. 

What is a pump pre-workout?

Pump pre-workouts are supplements designed to maximize muscle pumps. Usually, this is by including ingredients to enhance blood flow and oxygen to the muscles and increase cell hydration. 

Why do people use this as a stack?

Lifters combine a pump pre-workout with another pre-workout to get maximum performance benefits. 

The pump pre-workout is designed to deliver maximal pumps and work alongside the benefits of the other pre-workout being taken, usually stimulants.

Transparent Labs Bulk vs. Lean Pre-Workout

Another common thing people want to know is the difference between Transparent Labs Bulk vs Lean Pre Workout. 

Both are part of the Transparent Labs PreSeries, but they have different uses.

PreSeries Bulk by Transparent Labs is designed particularly for building muscle, whereas PreSeries Lean is a pre-workout made especially for cutting. 

Also, Transparent Labs Bulk and Lean have many similar ingredients, but Bulk generally has higher doses of those ingredients (e.g. citrulline malate, beta-alanine, betaine). 

And of course, they have their own unique ingredients, too. For example, Bulk has different anabolic micronutrients, whereas Lean has specific micronutrients for thyroid health and metabolism.

Feels like a dependable boost for those tough workouts.” – Ian T. 

“On my second container of Bulk. This supplement works great and it’s comforting knowing I’m not putting artificial colors, sugar or worse yet artificial sweeteners into my body. Minor tingling but that’s to be expected. Absolutely no jitters. Thanks for creating such a clean product.” – Ramsey A.
