short introduction to PreSeries BULK PWO and Transparent Labs
PreSeries Bulk Pre-Workout from Transparent Labs is (as far as I am aware) a fairly new contender on the market of pre-workout supplements. I had never heard about this PWO or Transparent Labs before recently when I was contacted by them, asking if I would be interested in posting a review. I told them to send me a jar, so I would be able to share an honest review, and so they did. It's clearly easy to get a bit biased when offered a free jar in return of a review, but I promise I will try to be as fair and honest as I possibly can. With this short introduction,
PreSeries Bulk Pre-Workout Supplement Details
I received a jar in the mail a couple of weeks ago, and I have now had a chance to test over a couple of days, before going to the gym. At this stage, I got a pretty good feeling of how this pre-workout works, and what I can expect from a scoop of PreSeries Bulk Pre-Workout. The design is neat, with a clean and minimalistic look. The jar is a bit larger than the standard we tend to see these days (C4, 1MR, Jack3D, etc.). It packs a total of 633 grams which will give you a total of 30 servings. The price listed on Transparent Labs for this jar is $49, meaning that a serving is going to cost you $1.63. This is clearly in the more expensive end of the typical range for pre-workout supplements, but there is a good reason, which I will get to later.
One thing I really like is that you get a really good serving size here. I have never been a fan of the concentrated (often super concentrated) pre-workout supplements. After all, how much of something can you squeeze into almost nothing? Lucky me, PreSeries Bulk Pre-Workout isn't a concentrated PWO - quite the opposite actually. With the 100% fully disclosed supplement facts, we know exactly how much of what we get; and we get a lot! All the substances are covered in details further down in this post.
Although clients clearly prefer transparency when it comes to supplement facts, the majority of companies still hide behind
PreSeries Bulk Pre-Workout is completely transparent with everything fully disclosed. This is a big plus in my book!
In addition to this, there are a couple of other things to note here:
- Ingredients used at clinically effective dosages
- Zero colored dyes
- No Unnecessary fillers
- No Harmful additives
- Stevia as sweetener
When compared to other pre-workout supplements on the market, this is a clean as it gets. The name Transparent Labs really is a good reflection of this supplement they have pushed to the market. With these details,
PreSeries BULK Pre-Workout - in their own words
PreSeries BULK was developed for a specific purpose - to be the most exceptional "bulking" pre-workout supplement available. The key ingredients, all backed by published scientific research, are included at clinically effective dosages and contain zero colored dyes, unnecessary fillers, or harmful additives.
With 100% formula transparency and a potent Testosterone Support complex (vitamin D3, boron, and zinc), PreSeries BULK is most effective for serious athletes and bodybuilders looking to gain size and increase muscle mass.
There's a reason why PreSeries BULK comes in jumbo-sized jugs! Each serving exceeds 22 grams and includes 20 active ingredients that are designed to increase nitric oxide ("pump") and focus while working out, reduce fatigue and muscle soreness, all while enhancing overall physical performance.
Sounds good and I promise you it is. But before I share the details of how this stuff works and what it feel's like, I want to cover the details of the substances used in PreSeries Bulk, so you know exactly what it is that makes this PWO stand out from the crowd.

Supplement Facts in details
Testosterone Support Complex
Vitamin D3 is listed as the first part of the testosterone support complex, with a total of 3,000 IU's. Most people are familiar with this vitamin. Vitamin D is synthesized in the skin when exposed to sunlight and it good for
Zinc is one of many essential minerals your body needs from dietary sources as your body cannot
Just like vitamin D3, Zinc has been shown to increase testosterone levels, if you are in zinc deficit. For most people with a solid and diverse diet, this probably
Boron (as boron citrate)
Boron is a dietary mineral which has shown some promise in regards to raising testosterone and free testosterone levels. Boron is found in various natural sources such as avocado, cherries, apple juice, grape juice, peaches, etc. However, getting 5 mg daily from natural sources would require some seroius effort. PreSeries Bulk Pre-workout makes it easy.
Mechanistically, concentrations of boron in vitro in testicular homogenates are not associated with conversion rates of androstenedione to testosterone.
One study in otherwise healthy men noted that acute supplementation of Boron, over the period of 6 hours, failed to increase total testosterone levels yet trended to increase free testosterone (+14.7%) and DHT (+9.9%) although neither was statistically significant, yet significantly reduced Sex-Hormone Binding Globulin (SHBG) by 9% at the 6 hour mark yet required 2 hours to reach significance. After 7 days of supplementation, the increase in free testosterone (28.3%) reached significance yet the SHBG decrease was not. Another study using 4 weeks of 10mg Boron supplementation noted a trend towards increased testosterone (11.4%) but failed to reach statistical significance.
One study has been conducted on athletic males participating in bodybuilding, using a lower dose. 2.5mg of Boron daily for 9 weeks elevated plasma boron levels (20.1ppb to 32.6ppm; a 62% increase) yet failed to find significant differences between groups for any hormones measured.
In healthy male adults, supplemental Boron appears to be have mixed results. It has been implicated in increasing testosterone, but these may be dependent on time or dose as prolonged studies with the same or a lesser dose fail to replicate the increase in free testosterone seen in one study
If you want to know more about Boron as a testosterone boosting mineral, you should read this great article from Cristopher Walker over at TestShock.
This sums up the testosterone supporting complex. With the addition of boron, this might actually do you some good, even if you
Citrulline Malate 2:1
Citrulline is a common substance in pre-workout supplements these days and for a good reason. Citrulline is a precursor to the amino acid Arginine, which is a precursor to Nitric Oxide and we all know what
The short version is that when ingested, Citrulline is converted into Arginine. This is then converted into Nitric Oxide, which helps to bring about more pumps.
Although it's often used in PWO's it tends to come in smaller dosages. Pre JYM is one of the few that also gives you a full clinical tested dose at 6g, which is what you get in PreSeries Bulk Pre-workout. At 6,000 mg, this stuff does it's job very well!
One of the most recognized substances that you will find in almost every single pre-workout supplement on the market. I am personally a fan of beta-alanine. Lots of studies have shown that beta-alanine will have a positive impact on your bodybuilding efforts.
Beta Alanine is the limiting precursor to the formation of Carnosine in our muscles. There is enough scientific evidence now to prove that when
The short version is that supplementing with beta alanine will improve endurance, performance and strength, and combat fatigue. In pre-workout supplements, we tend to see it dosed around 2,000 mg, but here we get a total of 4,000 mg. This is enough to give you a heavy tingling sensation, which you probably either hate or love.
BCAA (branched-chain amino acids) are often used in intra-workout supplements, but also often seen as part of
This is an amino acid (which is also known as Trimethylglycine) that has been fairly well studied and shown to help enhance strength, power and musclemass through boosting your muscle protein synthesis, as well as promoting fat loss. Most studies showing benefit from a performance enhancing perspective is with individuals using around 2.5 grams daily, which is exactly what we get from a scoop of PreSeries Bulk Pre-Workout from Transparent Labs.
The substance you will find it in almost every single energy drink on the market, and yet few people tend to know what it does. Taurine is actually an amino acid - a conditionally essential amino acid meaning that
It acts as a cell hydration agent by pulling water into the cells. In addition to hydration, this also gives the user what some will consider a benefit - a water-based pump. Opinions on this matter are very shattered. Somelikes it while others don't. It's kind of the creatine bloat talk all over again. Finally, it has been shown to enhance endurance, focus and reduce soreness.
Tyrosine is a non-essential amino acid that acts as a precursor to Dopamine and Noradrenaline. Recently we have seen more and more supplements using N-Acetyl L-Tyrosine instead of just L-Tyrosine. N-Acetyl-Tyrosine is Tyrosine with acetic acid which allows for better absorption. This substance has gained tremendous popularity in recent years,
Choline Bitartrate is a
L-Theanine is one of my new favorite substances. I recently had my first run on an L-Theanine and Caffeine mix, which does have very obvious effects on focus and attention. The combination of L-Theanine and Caffeine is being hyped on various boards as a Nootropic wonder and I must say there is something true to this. It's not just all hype. A combination of 200 mg Caffeine and L-Theanine is noted to be synergistic in promoting cognition and attention. In this PWO we get more L-Theanine and less caffeine (but a bunch of other stuff that should make for the lack of the remaining 20 mg caffeine).
Although this is mostly talked about in nootropic forums, I think the addition of this to a pre-workout supplement is a perfect addition. It really makes focus in on what´s important and get it done. Don't mistake this for energy. Your mind just comes more clear on what to do. A brilliant addition to a pre-workout in my opinion!
The good old caffeine and at a perfect dosage. We all know what this stuff does, but just in case you have been you have been living under a rock, here is the short version: It will give you a physical and mental energy boost. The typical dosage tends to be closer to 200 mg and that is my personal sweet spot. Here we get a total of 180 mg which seems like a perfect choice, considering we get a bunch of other substances to boost energy levels as well.
Caffeine boosts energy in different ways.
Recognized for its medicinal properties since antiquity, the velvet bean is known to contain L-DOPA, an important precursor for the neurotransmitter dopamine. It has been studied in the treatment of Parkinsons disease and demonstrated to potentially have a neuroprotective effect.
An increase in dopamine production should lead to a better mood and less stress. In addition to this, L-Dopa has been shown to have a positive impact on our growth hormone levels.
I have mentioned this substance here on muscles.zone several times before, as it's becoming quite a common contender on the supplement facts on pre-workout supplements.
L-Norvaline is an analog of the branched chain amino acid, valine. It can be found in foods such as dairy, meat, grains, soy and peanuts. Since valine is an essential amino acid, L-Norvaline has to be obtained through your diet or via supplements, as the body cannot produce it.
With that being said, what is the specific reason for the inclusion in this pre-workout? The short version is that L-Norvaline indirectly promotes NO production. The reason for this is that L-norvaline is an inhibitor of the enzyme arginase and arginase is responsible for the breakdown of Arginine in the body. As Arginine is converted to NO, preventing it's breakdown equals more available NO.
Another common CNS stimulant that I have highlighted several times before, here on muscles.zone. It's often referred to as a weak version of Ephedrine, with a similar set of actions that can improve fat loss mainly by enhancing lipolysis and increasing the user's resting metabolic rate. It's stimulating effects are not comparable to that of ephedrine, making it an OK substance in a PWO, but the short version is that it's better suited for fat burners in my opinion. From an energy perspective, you can think of it as substance stronger than caffeine and weaker than Ephedrine. As mentioned above, with the 180 mg of Caffeine, I think the addition of Synephrine is a good call.
We are seeing hordenine in more and more pre-workout supplements and for a good reason. Although there aren't that many studies done on this stuff just yet, it is known to amplify and prolong the effects we get from caffeine. Hordenine, contained in Citrus Aurantium, acts as a beta-2 adrenergic and a Monoamine Reuptake Inhibitor. As a Monoamine Reuptake Inhibitor hordenine will amplify the effects from stimulants by blocking the reuptake of Noradrenaline.
Bioperine is an extract of black pepper. It helps to increase the absorption of the ingredients contained in Bulk Pre-Workout

VERDICT OF PreSeries BULK Pre-Workout from Transparent Labs
I am a fan. I love the clean design, the light flavor, the 100% disclosed supplement facts, the substances used and the dosing. This is not your typical concentrated PWO, where you wonder how it can pack so much. You get a solid jar with a big spoon, enough to give you a serving size of 21.11 grams - Now we are talking! I love that there is no space wasted on creatine nor sketchy novel substances that no one knows the consequences of.
The effects I get from this is second to none. It bests all the pre-workout supplements I have tested. This is both in terms of energy, pump and focus. This stuff gets me going! My recommendation is for you to try this and I bet you won't look back!
