With the headquarters located in Utah, their range of products cut across the following categories:

This company prides itself on its full disclosure of the formula behind its product composition, owing to a series of scientific research backing up the potency and efficacy of its ingredients.

Transparent Labs ranks among the top supplement-industry player when it comes to supplements for cutting fat, achieving fitness goals, and building muscle tissues.

Overview & How it works

The simple philosophy behind this product is that it helps you achieve bulking through increasing your testosterone level, stimulate your performance and enhance endurance using nitric oxide while also giving strength and stamina enough for a 2 to 3 hours non-stop workout session.

Unlike other products on the market that are capsules, Pre-series BULK is specially packaged into a paper-bag as a powder which is served with a scoop and about 30 servings.

With each scoop of approximately 22 grams comprising of 19 distinct high-performing ingredients blended in the right proportion to give you nothing but that positive and mind-blowing result that you always desired.

Another unique but yet fascinating fact about this product is that it comes in a variety of flavors- yes, you heard me right; you get to choose which flavor suits your taste bud between the strawberry lemonade, blue raspberry, orange, and sour grape option.

In fact, this product has continued to retain its status as one of the few scientifically proven ingredients with well-established clinically effective dosages.


I need not stress that the Pre-series Bulk pre-workout is “specially formulated” supplements endowed with not less than 19 carefully sorted ingredients as enumerated below:

With a 6000mg of Citrulline per serving of BULK supplement, it remains the principal ingredient in any pre-workout supplement. It has been clinically proven to increase blood flow, thereby giving you the much-needed strength and endurance for your workout sessions.

 The desire of every bodybuilder during exercise is to delay fatigue and increase workout time to the maximum- Beta-Alanine is an amino acid that helps to achieve this. This implies that you can rest assured that you can exercise as long as you want and still not feel any sense of tiredness whatsoever.

BULK contains BCAAs in ratio 2:1:1, It is the only carb ingredient in this supplement.  The inclusion of BCAAs is mainly is to deliver primary/necessary energy needed for the body to remain energized should incase your diet does not contain carb.

Based on scientific research, a minimum of 1500mg up till 2500mg is the effective dosage of Betaine required to significantly cut back fatigue, rapidly increase your inner strength and endurance while also simultaneously building muscle mass. BULK, therefore, contains just about the right amount of Betaine per serving.

It is vital to add Taurine as it has been found to work hand in hand with Beta-Alanine to limit soreness after-workout.

This is yet another major amino acid that made it to the ingredient table. It provides and improves focus, endurance, and memory, so you can completely finish up your exercise routine without leaving any stone unturned.

This is a combination of two potent stimulants in a very low proportion. Despite the addition of these two, you need not be bothered about the effect stimulant tend to have- such as sleeplessness, jitters, or temporary loss of coordination. Instead, you get a fast rush of energy to boost your overall performance. You might just need to be wary of the time of the day you take the supplements.

This is also popularly called Bitter Orange, Despite the findings of the National Center for Complementary and Integrative Health, which states that  “Only a few studies have investigated the usefulness of bitter orange as a dietary supplement for health purposes in people.” It has still been found to sharply raise your level of body metabolism, which translates to fat loss and excess calorie burning during the bulking cycle.

As you advance into your bulking experience, a major contributing factor to your success is testosterone. From studies, Vitamin D3, Zinc, and Boron provide more nutrients that enhance and support the production of testosterone in the body.

Vitamin D is for better cognition, adequate bone strength and structure, and enhancing high testosterone level up to 20% more.

Recent studies have tied testosterone levels to zinc supplementation in men. It also betters the immune system and stimulates enzymatic activities in the body.

This is often attributed to an increased level of testosterone production.

L-Tyrosine is a known amino acid, but, in this case, it has been acetylated with N-acetyl to further aid and improve absorption and effective direction of energy and focus that Pre-series BULK delivers during a workout.

Following a publication from the U.S National Institute of Health, “L-tyrosine drastically inhibits the effects of stress and improves mental focus and endurance.”

It helps to ensure extensive exercise by counteracting the effect of hypothyroid.In extreme cold, this still balances your body and gives the necessary drive.

This ingredient maintains acetylcholine level, which is much needed for intense exercising whilst also converting homocysteine to methionine in the BMHT pathway.

A naturally occurring constituent found in certain plants and fruits. It works jointly with synephrine to increase metabolic activities and boost energy. It is an adrenergic amino similar to ephedra.

All the aforementioned ingredients above can be classified as the most essential and basic ingredients for BULK. Other ingredients include:

Mucuna pruriens, which enhances your psychology during your workout, L-Norvaline is responsible for nitric oxide production, Coleus Forskohlii for fat loss, Cayenne Pepper for thermogenic effect and, Bioperine which aids the absorption of all other ingredients in the supplement, Black pepper.


According to the Manufacturer of BULK, a full scoop to 16-24 fl. Oz. of water is recommended for use 20 to 30 minutes before a workout for effective results.

With 30 servings per bag, you are sure of a month-long supply when you purchase a pack of BULK.  For first-timers, I would suggest you begin with half scoop to examine and observe your body’s tolerance level.

Make sure you thoroughly agitate the mixture and preferably leave for few seconds for foaming to clear.
