One of the most satisfying things about my job is seeing clients achieve their muscle mass goals. All that hard work and dieting can pay off once you finally get the bulk and body fat ratio you set out for.

With the majority of my clients, one of the first things we look at is introducing a pre-workout supplement to gain more from each training session. But the problem is many standard pre-workout supplements are not ideal for bulking.

That’s why I was delighted to see Transparent Labs introduce Preseries pre-workout bulk supplements.

But before you just order a tub, read through this review and let me show you what you can expect.

What Is Transparent Labs Preseries Bulk?


Transparent Labs Preseries Bulk is a pre-workout supplement that is specifically formulated to support growing muscle mass.

Unlike many other pre-workout products, it aims to have less of a chance of muscle wasting and weight loss.

Transparent Labs Bulk claims that it has chosen ingredients that are scientifically proven to help increase strength, endurance, physical and mental energy, muscle protein synthesis, and a boost in testosterone so that you gain more from every single workout session.

If it had been any other company, I probably would have been more suspicious because that’s quite a statement to make, and it’s just one of the few things we’ll cover in this review.

Nevertheless, our team did all the necessary research to look at the ingredient list and see what scientific support we could find.

What Are The Preseries Bulk Ingredients?

What Are The Preseries Bulk Ingredients

1 - Citrulline Malate

With an impressive 6 g per serving, citrulline may help boost nitric oxide to increase blood flow. The result could be better pumps, as well as aerobic performance [1].

Citrulline bound to malate, an organic salt of malic acid, an intermediate in the citric acid cycle. It is the most researched form of citrulline, and there is speculation about an independent role of malate in producing performance benefits

2 - N-acetyl L-tyrosine

This is one of the more interesting amino acids I found, with research suggesting that it may help with a reduction in stress levels and improved mental focus [2].

3 - Mucuna Pruriens

Despite many years of experimenting with supplements, this was a new ingredient to me. Studies have shown that it may help with an increase in testosterone levels [3].

4 - Vitamin D3, Boron & Zinc

This unique testosterone support complex provides vitamins and minerals (especially zinc) that your body needs in order to create testosterone. By adding these vitamins and minerals, you could be in a better position to increase your testosterone levels completely naturally [4].

5 - Black Pepper

Pepper extract doesn’t actually have a direct impact on energy and performance, but it may provide support for your digestive system to better absorb the nutrients from each serving [5].

6 - Beta-Alanine

The interesting thing about beta-alanine is that studies have shown that it may help reduce premature fatigue [6]. With 4 g in each serving, this may help bodybuilders to train just that little bit harder.

7 - Caffeine Anhydrous

Caffeine is a great stimulant, and it may provide two distinct benefits. With 180 mg per serving, you could gain some mental focus and motivation. But it has also been shown to trigger thermogenesis to reduce body fat [7].

8 - All-Natural Sweeteners And Flavors

The other standout feature on the ingredient list is that it only contains natural flavors and sweeteners. This doesn’t just mean that you avoid potentially harmful chemicals, but the flavors like strawberry lemonade and sour grape are a lot more natural.

What Does Transparent Labs Preseries Bulk Do

OK, so you now have some nerdy info about what Transparent Labs Preseries Bulk contains, but what does that all actually mean for your workout?

I’ve hinted at some of the effects based on the individual ingredients, but it might be more helpful to explain what you could expect to happen in your body. I always highlight 4 areas to my clients.

Energy: Once the ingredients are absorbed and enter your system, you may notice a more sustained energy level.

Strength: Through increased blood flow, your muscles may receive more energy and oxygen to boost overall strength. This may be noticeable through heavier weights or more reps.

Endurance: One of the main problems in high-intensity training sessions is fatigue. The more you can postpone feeling tired, the more lifting you’ll be able to do.

Motivation: Along with your muscles, your brain will also need to stay focused on the task. By raising mental energy levels, you may be able to stay motivated during a workout for longer.

Are There Any Side Effects?


I have been using a range of Transparent Labs products for several years now, and many of my clients use them a lot as well.

In regards to any pre-workout side effects, the good news is that there are only two instances which came down to isolated issues.

In one case, a client started taking a higher than the recommended dose, which caused some stomach upset; that doesn’t go down well at the gym.

In another case, a client had an allergic reaction to one of the ingredients, so we had to find a different option.

One tip I would give you is to take a small dose for a few days, just to make sure you don’t have a reaction.

Who Is This Suitable For?

Preseries Bulk is most suitable for any athlete who is trying to bulk up their muscles and achieve a much more toned and ripped appearance.

While it’s critical to have the right exercise routine with higher weight limits and lower reps in order to bulk, having the right dietary support is just as critical.

The real benefit from Preseries Bulk comes from the ability to push yourself just that little bit further.

Even if you just achieve a 5% improvement, when you add that up over a possible 6-week bulking phase, you could end up exceeding your goals or simply achieving them a lot sooner.

The majority of my clients that take this product would generally already be in pretty good physical shape, and they just need a little bit of a boost for their workout sessions.

How To Get The Most Out Of Supplement?

The main thing I always get my clients to do is to spend about a week experimenting with the timing of Preseries Bulk. We generally start off taking it about 30 minutes before the workout is due to start.

After a few days, you’ll notice the physical energy and mental focus kick in, and if that happens 5 minutes too early, then you know you can change the timing to 25 minutes before.

Within about a week, you should have this worked out for your personal needs.


Does Transparent Labs Bulk pre-workout have creatine?

No, Transparent Labs Bulk pre-workout doesn’t have creatine because the effects it would have are negated by the caffeine it contains. It would be an expensive performance ingredient with no actual benefits.

When should you take Transparent Labs Preseries Bulk?

You should take Transparent Labs Preseries Bulk about 30 minutes before your workout is due to start. Depending on how fast your digestive system may absorb the ingredients, it’s a good idea to try increasing and decreasing that time to find the ideal timing.

Do We Recommend Transparent Labs Bulk Pre-Workout

Many of my bodybuilding clients will simply not head into any workout session without taking this supplement.

The only exception may be light cardio days, where they don’t need the energy boosts.

Order yours today and try out the strawberry lemonade flavor first. It seems to be by far the most popular with my clients.

I’d also invite you to add your own Transparent Labs Bulk pre-workout review on our Facebook page so that others might see what actual results are being achieved.
