Bottom Line

PreSeries Bulk (v2) is one of the most complete formulas we've seen to date. 

Each 20+ gram scoop is specifically designed to increase blood flow, improve muscular performance, all while using a smooth and long lasting stimulant blend.

Bulk contains highly bioavailable minerals and vitamins to help with testosterone production, as well as nootropics to optimize focus.

And it doesn't have any artificial colors, preservatives or coloring, making this one of the most future-proof pre workout's we've seen to date.

PreSeries Bulk: Who Is Transparent Labs?

Transparent Labs is one of the best supplement companies. 

Unless you've been living under a rock (or a squat rack), you've probably heard of this company. 

If you haven't, then you're probably thinking, like us, another lab company, eh?

But they are much more than that.

Just like their name, they are excellent with transparency with their supplements and formulate everything with full dosages without using any artificial ingredients (uses only natural colors and flavors).

This Utah-based company is one of the most recommended when it comes to clinically dosed supplements. 

You won't find Transparent Labs supplements on Amazon, eBay, GNC, Walmart or really any small or big retail stores.

Who buys from GNC with their high prices anyway?

But they ship worldwide.

You won't have to deal with the extra fee's retailers would take (I'm looking at you GNC).

They don't spend anything on marketing, they have spread quickly because of their reputation. 

This makes their products cheaper, passing on the savings to you. 

PreSeries Bulk is one of their 3 pre workouts, along with Stim-Free and Lean.

We're going to breakdown the ingredients, so you know what you should (and shouldn't) expect.

PreSeries Bulk Benefits

Bulk features a fully transparent label with research-backed ingredients.

You'll even see dosages for the “other/inactive” ingredients.

From muscular endurance pump inducing to strength/muscle growth ingredients and testosterone support

Very few pre-workouts have successfully used the same formula for more than 5 years in a row.

The unique aspect of this formula is the testosterone blend.

[Check out Vitality, the newest test booster from Transparent Labs]

It uses natural ingredients to enhance the “natural” production of testosterone.

And it seems other sites seem to place this pre-workout high on their list.

Being future-proof and containing the best ingredients you would ever need for a tough workout (and nothing you don't need),PreSeries Bulk will undoubtedly be a top choice for years to come.

  • There's a few things that make this one stand out from other pre's:
  • Zen-like Focus (Theanine combined with caffeine)
  • Generous Dosages of Citrulline Malate and Beta Alanine
  • Creatine Free
  • Natural sweeteners (Stevia) and no artificial colors

Transparent Labs Bulk Price

Considering how much PreSeries Bulk packs, it's price shouldn't be a surprise.

It's priced at 49$.

But using the 10% off coupon, it's cheaper than Pre Kaged and Pre Jym ($1.74 vs Bulk's $1.4 per serving) 

Use this coupon code: FITFREK.

And as the same suggests, Bulk is made for those who have the goal of gaining muscle.

You may find cheaper pre-workouts but they contain half the dosages and require double servings for full servings, or they may be a pre workout of just stimulants.

Any pre-workout that contains as much as Bulk will have the same pricing structure but getting multiple bottles will cut down costs.

If you get 2 then it goes as low as $40 each.

If you're focused on cutting, check out PreSeries Lean, it features nearly the same ingredients except with a thyroid blend for increasing thermogenesis.

If you're looking for the strongest pre workouts.

Or if you're not sure and want something for performance / gains, go through our buying guide for pre workouts.

Compared to the hardcore pre workouts that have just 5 grams per serving, Bulk has 24 grams per serving but still costs about the same as it only requires one scoop to get full dosages.

In this review, we'll dig into each ingredient and how it is beneficial for power, endurance and muscle gains.

And women can take this pre workout. 

And ladies, don't let the “testosterone blend” intimidate you.

The testosterone blend made out of minerals and natural ingredients that can be taken by both genders.

You'll find out in this review why the Transparent Labs Pre Workout is one of the best, future-proof formula's we've found to date.

If you want less beta alanine and more weight loss ingredients, check out Transparent Labs Lean pre workout.

My Review

When it comes to pre-workouts, I enjoy the potent ones.

As you have probably guessed, exotic pre workouts like Crack and Excelsior are some of my favorites.

So when I look at Bulk and see the 200mg caffeine and the other stims that are nothing like the kind that I'm used to, I don't think anything of it.

But that's the thing about Bulk.

It doesn't put you through the high level of energy, along with the crash that typically follows a few hours after.

I've taken Bulk for months and after I come off, I don't feel any different nor do I feel like I need 400mg of caffeine to function normally.

That's why I like and recommend Bulk, it's reliable and it doesn't build up a dependency that puts me through withdrawals or cravings for more.

Here's my review on it…

As soon as I start drinking it, I can feel the tingles that come from beta alanine.

And it isn't like normal tingles, it's heavy because the dose is huge, 4g is the biggest I've seen in a pre workout and it certainly isn't your average.

By the time I get to the gym, about 45-60 minutes later, I feel like the energy has built up nicely and I don't feel any jitters or anything that would typically come from a heavy stim pre workout.

It's a steady flow of energy.

And when I get past my warm up sets, I feel like I'm well connected and pumped to lift heavy.

I've taken this on empty stomach and in a fasted state where I wouldn't have breakfast, just perhaps a banana.

I feel like the minerals and vitamins here help ensure my body gets the foundation of nutrients it needs before a workout, and with the nootropics on top of it, I'm a pretty focused state hours after my workout.

Citrulline malate combined with betaine anhydrous and taurine helps with pumps.

It would've been nice to get some agmatine to prolong the pumps, but all in all, the energy is perfect for a daily pre workout and the effects build up thanks to the ergogenic aids.

And since it's naturally flavored and sweetened, you won't have to worry about putting the extra stuff that you don't need in your body. 

This is one of our favorite naturally flavored pre-workouts. 

PreSeries Bulk Ingredients

Guess what?

Transparent Labs has upgraded this pre workout to V2 for the first time in years.

They have changed a few things.

We'll breakdown these changes here, we'll discuss what was removed and what was added.

We've put the old label beside the new one so you can see the changes, see below: 

What remains the same is the clinical doses of citrulline malate, BetaPure betaine anhydrous, beta-alanine, and taurine.

Transparent Labs believes that this is the foundation of Bulk and it’s where the strength of it comes from.

Not to mention these ingredients also help with muscle volumization and nitric oxide production. (1234)

The minerals also remain the same as it has zinc chelate, boron citrate and vitamin D3.

These ingredients are specifically put in for testosterone support. (567)

The stimulants are the same too, with the huge dose of theanine at 360mg paired with 210mg caffeine.

This ratio is due to research showing effectiveness when used together for optimal cognitive function. (8910)

What was changed?

These ingredients have been removed:

  • Mucuna pruriens
  • Synephrine HCl
  • Hordenine
  • L-Norvaline

And they’ve been replaced with:

  • AlphaSize alpha-GPC (300mg)
  • Theobromine (50mg)
  • 200mg PurCaf Organic Caffeine (200mg)

The removed ingredients were unnecessary as Transparent Labs felt the added ingredients prove much more useful when it comes to cognitive function, while enhancing focus and reducing the onset of fatigue. (111213)

And Bulk now features tyrosine, instead of N-Acetyl L-Tyrosine.

Switching N-Acetyl L-Tyrosine to plain L-tyrosine is not only cost effective but it’s more effective.

N-Acetyl L-Tyrosine does a poor job at converting to L-Tyrosine and even if it does, it doesn’t do it at the rate that Tyrosine does as the study shows here.

BioPerine was helpful with bioavailability but it’s been replaced with something better and that’s Astragin.

Astragin is an adaptogen and it can help increase bioavailability and uptake of ingredients taken alongside it but it can also be paired with BioPerine.

And finally, but not least, is the minerals (potassium and sodium) and Vitamin B6 / B12.

The reason why creatine isn’t here is because they have a standalone post workout for creatine which is also paired with HMB to maximize strength gains.

Transparent Labs lives up to their name as they've fully disclosed their fillers (as you can see in the picture above). 

With the scoops being almost as big as protein scoops, you'll see why you should start utilizing this bazooka of a pre workout to make some more gains. 

It's got everything from nitric oxide (8 grams of citrulline malate), testosterone support to betaine anhydrous for strength and muscle gains.

While this isn't going make you feel like you're on crack (like our strongest pre workouts), you'll definitely be making some gains, and getting some insane pumps, thanks to the profile. 

You can buy bulk ingredients if you're really after the “perfect pre workout” and customize it in any way that you choose it.

We got a guide if you'd like some help finding the perfect pre workout for yourself.

Testosterone Support

What's a pre-workout without some testosterone support?

Just in time for bulking season if you ask us!

Most pre-workouts have vitamin B complexes, C, and maybe some electrolytes.

But only a very few actually have testosterone-supporting vitamins like what you see here.

Zinc (10mg)

Zinc may as well maybe one of your favorite ingredients. If you exercise intensely, you're most likely to be low on this.

With high exertion (both in the gym, and in life; stress), your testosterone levels naturally decrease but research has found that supplementing with zinc prevents that, as it helps promote higher free testosterone levels and not to mention improved endurance and thyroid levels. 

Zinc is one of the essential minerals that is involved with maintaining many of the normal body functions. If you're serious about making gains or just being healthy, you'll want to have this in your supplement arsenal.

Boron (3000mcg)

Another essential mineral that you should be using. It's been shown to maintain and improve bone health. 

An interesting find on this mineral in studies, is that it tends to decrease SHBG (sex-hormone-binding globulin), a protein that binds to testosterone in the blood.

Decreasing SHBG means that you can have more testosterone free and help you make more gains. It's basically like an anti-estrogen which is perfect in any testosterone booster.

Citrulline Malate (8g)

The everlasting ingredient of the bunch. Citrulline Malate is awesome for endurance, pumps and delaying fatigue.

It's the super version of arginine as it's more bioavailable and much more effective.

Citrulline is the amazing ergogenic ingredient that can increase overall performance.

The increase in nitric oxide will lead to more endurance, increased overall performance and strength. Like beta-alanine, it buffers ammonia and lactic acid, leading to greater output in performance and making you last through an intense workout more efficiently.

It has the perfect dosage as it's recommended to have anywhere from 6-8 grams of citrulline malate pre workout. If you're looking for pure citrulline rather than the malate version, check out Pre-Kaged.

Beta Alanine (4g)

After learning what citrulline malate does (buffers lactic acid), including beta-alanine just further makes this pre workout nearly limitless for increasing performance and gains.

What beta-alanine does is that it binds to histidine and turns into carnosine, which is super effective for buffering lactic acid.

With 4 grams per serving, you'll undoubtedly experience a tingling sensation (some people naturally don't) but it's totally safe and temporary.

Rest assured though, you're getting the full clinical dosage. There are shortcuts taken here by Transparent Labs.

Betaine Anhydrous (BetaPure™) (2.5g)

Betaine Anhydrous is a compound derived from the amino acid choline.

It's often found in various plant species, most notably sugar beets.

This compound is recognized for promoting protein synthesis in the body.

Betaine Anhydrous is commonly used in supplements due to its potential benefits for physical performance and body composition.

Research has shown that it can help increase muscle strength and size by enhancing the body's production of creatine.

It also plays a role in liver function and detoxification.

In addition to these benefits, Betaine Anhydrous has been found to reduce the risk of heart disease by reducing the levels of a molecule called homocysteine in the blood.

A study published in the Orphanet Journal of Rare Diseases found that Betaine Anhydrous was well-tolerated and effective in reducing plasma homocysteine levels in patients with homocystinuria, a genetic disorder that affects the body's ability to process certain proteins.

Another study published in the Italian Journal of Animal Science found that Betaine Anhydrous supplementation improved broiler chickens' growth performance and breast muscle quality, suggesting potential benefits for muscle growth and recovery in humans as well.

However, it's important to note that while Betaine Anhydrous has been shown to have several potential benefits, more research is needed to fully understand its effects and optimal dosage.

As always, it's recommended to consult with a healthcare professional before starting any new supplement regimen.

You can learn more about betaine from following scholarly articles: Betaine anhydrous in homocystinuria, Effect of betaine, a methyl group donor, and Dietary Betaine Addition.

Taurine (1.3g)

Mainly a muscle volumizer (and a mental focus enhancer), taurine works to pull in more water and nutrients to the muscle.

It's not so much of a nitric oxide ingredient as it is a water filler. It's like glycerol monosterate but it's a conditionally essential amino acid so your body does need it (it's present mainly in the heart, brain and skeletal muscle).

When taken alongside citrulline and the other soreness “fighters” here, it works much better in making you feel more recovered and fresh.

L-Tyrosine (1g)

Like taurine, Tyrosine can be consumed through food and the body produces it.

But in times of stress, like exercise or lifestyle, it’s depleted much quicker.

It helps to take it in supplement form.

Research from the journal of Military Medicine discovered that low levels of catecholamine neurotransmitters can negatively affect physical and mental performance. [14]

And this is where tyrosine is useful because it’s a precursor to a few catecholamine neurotransmitters like dopamine, norepinephrine and epinephrine. And as a precursor, it can produce more of these neurotransmitters and will help delay mental and physical fatigue, thus improving your workouts. [15].

Tyrosine is the best form you can get, which is why Transparent Labs have replaced N-Acetyl L-Tyrosine with it.

AlphaSize Alpha GPC (300mg)

Up next is one of the best forms of choline you can get.

Alpha GPC is often used in supplements to help increase focus, as well as strength and bodybuilding. 

In fact, research done by the Journal of the International Society of Sports Nutrition found that using 600mg of Alpha GPC supplemented for 6 days increased lower body strength by a significant amount. [16]     

This means supplementing with Alpha GPC will help increase strength, mostly in the lower body, but there isn’t enough research to confirm that this can also help with upper body strength. 

The main highlight of Alpha GPC is its ability to bring clarity and focus as it can enhance one’s cognition functions.

This will help enhance that mind to muscle connection and increase overall power output. [17], [18]

L-Theanine (200mg)

Present in green tea, L-Theanine promotes a smooth-like focus when helps prolong the effects of caffeine and keeps you in a “zen-like” focus. 

With a 2:1 ratio, there's 360mg of l-theanine and 180mg of caffeine. 

It's another nootropic that'll get you more connected to your muscles, thus increasing that mind-to-muscle connection we are all after.

Basically you'll feel more in control of the energy that you get from caffeine. 

No anxiety, stress, or anything that gets you shaky and looking like a crack-head on pre workouts!

Organic Caffeine (200mg)

Caffeine is the powerhouse of energy, caffeine simply helps you feel more awake, alert and “in the mood”. 

Some pre workouts have it dosed at 500mg, some have it at 100mg, some don't have it at all (stim-free)

The clinically studied and proven dosage is at 250mg to 300mg.

The 180mg dosage included here won't get you feeling like you want to jump off a building and fly to China, but it will be enough to get you feeling like a Jedi with a controllable force that is in the zone.

Pre workouts are meant to increase overall performance and have you making more gains.

So if you're looking for a pre workout to help you jump off walls and make you feel temporarily awesome without making the most out of your gym efforts, then you should either take a look at our strongest pre workouts or our buying guide.

Theobromine (50mg)

This is the cousin of caffeine and it’s often paired with stimulants to help produce more energy.

Theobromine works more in the body than in the mind unlike caffeine.

While they are both related, theobromine works by producing feel-good, euphoric energy.

It doesn’t increase heart rate, so the boost isn’t going to make you feel anxious, but it’ll rather produce a nice steady feel-good state. [19]

This works well when it’s paired with tyrosine which is also in Bulk.

BioPerine (5mg)

All of these ingredients are better absorbed when something like this is included.

Astragin increases the bioavailability of all the ingredients that it’s taken with.

It’s a proprietary blend of two plant extracts, Panax notoginseng and Astragalus membranaceus. Both of these ingredients work in synergy to enhance transporters in the intestines. [20

This compound is widely used in supplements for various purposes including gut health, which makes it a superb addition in Bulk.

Flavors Available

PreSeries Bulk comes in 3 10 different flavors and they've recently improved their flavors to taste a bit better. 

And even when it tasted a little bad, everyone was and still is addicted to this stuff because it works so well.

Since we've written this, they have revised and improved the flavoring system with Bulk V2, thanks to the users' feedback. 

Now they have 10 different flavors available (they come out with new flavors almost yearly).

Bulk vs Bulk Black

When comparing BULK and BULK Black (read Bulk Black vs Bulk review here), there are several key differences to note in their ingredient profiles:

  • Citrulline Malate: BULK Black contains 8g of citrulline malate, while BULK contains 6g. This means BULK Black offers a higher dose of this ingredient, which is known to enhance nitric oxide production and improve workout performance.
  • Betaine Anhydrous: Both BULK Black and BULK contain 2.5g of betaine anhydrous, a compound known to increase muscle strength and power.
  • Caffeine: BULK Black contains 275mg of caffeine anhydrous, while BULK contains a slightly lower amount at 200mg. This means BULK Black may provide a stronger energy boost.
  • Theanine: BULK Black contains 200mg of theanine, while BULK also has it at 200mg. Theanine is known for its ability to promote relaxation without causing drowsiness.

Transparent Labs has given its Bulk Pre-Workout a serious upgrade, and they've also brought back the crowd-pleaser, Bulk Black.

Here's the scoop:

The new Bulk formula keeps its rock-solid foundation of science-backed ingredients, but it's been supercharged for even better results.

The L-Citrulline Malate has been bumped up from 6,000 mg to a whopping 8,000 mg per serving for next-level blood flow and pump.

The Infinergy™ Di-caffeine Malate has been given a boost from 30 mg to 45 mg for laser-sharp focus.

And the Astragin™ has been doubled from 25 mg to 50 mg per serving to supercharge the absorption of all those other powerhouse ingredients in Bulk.

They've also dialed back the Zinc Chelate from 30 mg to 10 mg and L-Theanine from 360 mg to 200 mg per serving. Plus, they've swapped out BCAAs for a higher dose of citrulline malate.

Now, let's talk about Bulk Black. This is the "big brother" of the original Bulk formula.

It's packed with extra caffeine, B vitamins, and vitamin D. With nearly 300 mg of caffeine per serving, Bulk Black is the go-to for those who crave a more intense pre-workout kick.

So, what's the bottom line?

The main differences between Bulk and Bulk Black come down to their caffeine content (Bulk Black packs a more potent punch), and their formula tweaks (Bulk has been fine-tuned for maximum effectiveness).

Both products stay true to Transparent Labs' commitment to 100% label transparency and are free from artificial sweeteners, preservatives, and food dyes.

It's all about giving you the best bang for your buck.

Bulk vs Lean

Comparing BULK vs LEAN, the differences are more obvious:

  • Citrulline Malate: Both BULK and LEAN contain 6g of citrulline malate, known to enhance nitric oxide production and improve workout performance.

  • Beta Alanine: BULK contains 4g of beta alanine, while LEAN contains a lower amount at 2g. Beta alanine can help improve athletic performance and exercise capacity.

  • Betaine Anhydrous: Both BULK and LEAN contain 2.5g of betaine anhydrous, a compound known to increase muscle strength and power.

  • Acetyl L-Carnitine HCl: LEAN contains 1g Acetyl L-Carnitine HCl, an ingredient not found in BULK. This compound can help the body produce energy and is important for heart and brain function.

  • Choline Bitartrate: LEAN contains 500mg of choline bitartrate, another ingredient not found in BULK. Choline is an essential nutrient that supports various bodily functions, including cellular growth and metabolism.

  • Caffeine: Both BULK and LEAN contain 180mg of caffeine anhydrous, known to improve athletic performance and endurance.

  • BioPerine: LEAN contains 5mg of BioPerine, an ingredient not found in BULK. BioPerine is a black pepper extract that can enhance the absorption of other nutrients.

Bulk vs Pre-Jym

Transparent Labs' Bulk and Pre Jym are two heavyweights that often go head-to-head.

Both are designed to supercharge your workouts, but they each have their unique strengths and quirks.

Let's dive in and see how they stack up against each other.

First off, Bulk by Transparent Labs is a pre-workout supplement that's laser-focused on supporting recovery and weight gain.

It's designed to stimulate growth through enhanced workouts and immediate post-workout recovery support.

It's a two-pronged approach that makes Bulk a standout in the market.

Bulk's ingredient list is impressive. It includes a blend of caffeine (both anhydrous and DiCaffeine Malate), vitamins (B6, B12, and D3), minerals (Sodium, potassium, zinc, and boron), and a host of other compounds designed to improve mental performance, muscle metabolism, and post-workout recovery.

On the other hand, Pre Jym is a more generalist pre-workout supplement.

It doesn't specifically target weight gain like Bulk does, but it still offers a potent mix of ingredients designed to enhance workout performance and recovery.

Pre Jym's ingredient list includes creatine, beta-alanine, betaine, taurine, A-GPC, Huperzine, citrulline, beetroot extract, BCAAs, and piperine. It's a well-rounded blend that aims to improve wakefulness, workout performance, and post-workout recovery.

When it comes to comparing the two, Bulk emerges as the more focused and synergistic option.

It's designed with a clear goal in mind and uses powerful synergies to achieve that goal. Plus, it offers better value for money than Pre Jym.

Pre-Jym, while still effective, lacks the clear design direction that Bulk has.

It's a good all-rounder, but when it comes to specific goals like weight gain, Bulk takes the lead.

In conclusion, both Bulk and Pre Jym are excellent pre-workout supplements, each with its unique strengths.

If you're targeting weight gain and recovery, Bulk is your go-to option.

If you're looking for a more general pre-workout supplement, Pre Jym is a solid choice.

Transparent Labs BULK vs Pump

Transparent Labs Pump is a pre-workout supplement that's designed to enhance muscle pumps and performance without the use of caffeine or other stimulants.

It contains ingredients like L-Citrulline, Arginine Nitrate, Betaine, Glutathione, BioFolate, and Vitamin C. Compared to BULK, Pump lacks stimulants but includes GlycerPump for enhanced muscle pumps.

It also includes Tyrosine, Sodium and Potassium, and AstraGin for absorption.

Transparent Labs BULK vs Gorilla Mode

Gorilla Mode is a pre-workout supplement that emphasizes its high stimulant content.

It contains L-Citrulline, Creatine Monohydrate, GlycerPump, Betaine Anhydrous, L-Tyrosine, Agmatine Sulfate, Caffeine Anhydrous, N-Phenethyl Dimethylamine Citrate, BioPerine, and Huperzine A.

Compared to Transparent Labs BULK, Gorilla Mode has a higher caffeine content and includes additional ingredients like Creatine Monohydrate and GlycerPump.

However, BULK has a more diverse vitamin and mineral profile.

Transparent Labs BULK vs Stim-Free

Transparent Labs Stim-Free is a pre-workout supplement that's designed for athletes and gym-goers looking to enhance performance without caffeine/stimulants.

It contains key ingredients like citrulline malate, beta-alanine, betaine, and taurine.

It's recommended for anyone intolerant to stimulants/caffeine and is looking to "cycle off".

Compared to BULK, Stim-Free lacks stimulants but includes powerful nitric oxide boosters like L-citrulline and betaine anhydrous.

Transparent Labs BULK vs Lean

We broke down the comparison between BULK and Lean earlier.

Basically, BULK is more focused on muscle building with a higher content of Citrulline Malate and Beta Alanine, while Lean is more geared towards weight loss with ingredients like Acetyl L-Carnitine HCl and Choline Bitartrate.

BULK is generally safe for healthy adults when used as directed.

However, it's always a good idea to consult with a healthcare professional before using any new supplement, especially if you have a medical condition or are taking medication.

6. Can I use BULK if I'm sensitive to caffeine?

BULK contains caffeine, so if you're sensitive to caffeine or other stimulants, you might want to start with a lower dose or choose a caffeine-free pre-workout supplement.

7. Can I use BULK if I'm pregnant or nursing?

As with most dietary supplements, if you're pregnant or nursing, it's best to consult with a healthcare professional before using BULK.

8. Can I use BULK if I'm under 18?

BULK is intended for adults and should not be used by individuals under the age of 18.

9. Where can I buy BULK?

BULK can be purchased directly from the Transparent Labs website or from various online retailers.

10. Does BULK contain any allergens?

BULK is free of gluten and GMOs. However, it's always a good idea to check the label for the most up-to-date ingredient and allergen information.

11. Why is there no creatine in Bulk?

Transparent Labs suggests taking creatine post-workout as evidence shows that creatine is better absorbed after exercise. They offer a standalone creatine monohydrate supplement with HMB.

12. What is the difference between Bulk and Bulk Black?

Bulk Black Pre-workout is a "harder-hitting" version of the original Bulk formula. The major difference between the two is the additional caffeine, B vitamin, and vitamin D content in Bulk Black. With nearly 300 mg of caffeine per serving, Bulk Black is designed for those who want a stronger jolt before training.

12. What flavors does Bulk Pre-Workout come in?

Bulk Pre-Workout comes in a variety of delicious fruit flavors, including Blue Raspberry, Tropical Punch, Orange, Strawberry Lemonade, Lemon Lime, Sour Grape, Green Apple, and Watermelon. Bulk Black comes in a black cherry flavor.

13. What is the commitment of Transparent Labs to full-label transparency?

Transparent Labs is committed to full-label transparency. Every ingredient in their products, even the inactive natural flavoring and stevia, is listed in exact doses. They want customers to be confident about what they're getting and what they're not getting in their dietary supplements.

14. Is Transparent Labs Bulk Vegan-Friendly or Vegetarian-Friendly?

Yes to both! Transparent Labs Bulk Pre-Workout is vegan-friendly. This information is confirmed on the product's page on the Transparent Labs website.

Future-Proof Pre Workout

We're as guilty as anyone.

Pre workouts with 5 gram servings seemed great.

They usually contained several ingredients, in a mega prop blend, in undisclosed dosages.

But PreSeries Bulk has changed things for the better.

It redefines what pre workouts are suppose to do.

Proper and clincially dosed ingredients are blended together to help take workouts and performance to the next level.

In result, gains come at a faster pace and you have an edge to break PR's. 

You'll recover faster, feel less soreness, get more pumped, and feel more in the zone.

And the servings are the size of protein scoops and there isn't any artificial flavors or dyes. 

A pre workout needs to be reliable.

It needs to not be 100% energy focused.

And that's why we believe PreSeries Bulk is future proof.

It's everything we could ask for in a pre workout that's as close to natural as possible. 

Transparent Labs has engineered something super, and it's sustainable to use for the long term.

It doesn't need to be reformulated in any major way and it's proved this over the past few years with it's growing popularity. 

They do have a stim-free version which is great if you're looking to take a break from stimulants.
