How should PreSeries BULK be taken to maximize its effectiveness?
In terms of timing, we recommend taking PreSeries BULK 20-30 minutes prior to your workout. In terms of how much water to drink with PreSeries BULK, we recommend mixing 8-12 fl. oz of water with 1/2 scoop (to assess tolerance) and mixing 16-24 fl. oz of water with 1 full scoop.
How does PreSeries BULK compare to other pre-workouts?
Back in 2014 we set out to make the best pre-workout supplement, regardless of price, without the artificial nasty ingredients so common in packaged goods. We wanted something WE would be comfortable taking daily, and confident that it would get the job done. If you want to see how we compare PreSeries BULK to other well rated pre-workouts, check out our best pre-workout blog post here.
I am subjected to drug testing for my sport, can I take PreSeries Pre-Workout?
Yes, absolutely. Transparent Labs contains zero illegal drugs of any kind. Depending on how rigorous your drug-testing procedures, we recommend showing your coach or administration our supplement facts panel.
Why doesn't PreSeries BULK contain creatine?
Large doses of caffeine negates the ergogenic effects of creatine. PreSeries BULK contains 180 mg of caffeine anhydrous.
What is the difference between PreSeries BULK, PreSeries LEAN, and PreSeries STIM-FREE?
PreSeries BULK is designed to support lean muscle growth and includes a testosterone support complex, while PreSeries LEAN is designed to support fat loss and includes a thyroid support complex. PreSeries STIM-FREE, as the name suggests, contains zero stimulants and has added elevATP.
I don't live in the United States, can I still buy PreSeries BULK?
Yes - our fulfillment center allows us to ship worldwide. Standard shipping for international orders typically takes 10-14 business days to arrive.
Does Transparent Labs ship to my Country?

|What is the difference between PreSeries BULK, PreSeries LEAN, and PreSeries STIM-FREE?||PreSeries BULK is designed to support lean muscle growth and includes a testosterone support complex, while PreSeries LEAN is designed to support fat loss and includes a thyroid support complex. PreSeries STIM-FREE, as the name suggests, contains zero stimulants and has added elevATP.|
|Does this product contain nuts?||We process products in our facility that have nuts (coconuts, peanuts). However, we have an allergen control program in place that sanitizes and cleans our equipment between allergen and non-allergen runs!|
|Is this product vegan?||Yes. PreSeries BULK Pre-Workout is vegan.|
|Citrulline Malate 2:1 | 8,000 mg|
From a performance standpoint, citrulline malate is the “star child” of pre-workout science. We chose citrulline malate over L-arginine because it provides better absorption, higher plasma arginine levels, and has been found to:
PreSeries BULK contains 8,000 mg (8 grams) of citrulline malate per serving.
|Beta-Alanine | 4,000 mg|
Supplementing with beta-alanine has been proven to increase cellular carnosine levels, which are quickly depleted during intense exercise [6, 7].
A majority of pre-workout supplements contain beta-alanine, but at significantly underdosed levels. Supplementing with proper dosing, as found in PreSeries BULK, is shown to:
PreSeries BULK contains 4,000 mg (4 grams) of beta-alanine per serving.
|BetaPure™ Betaine Anhydrous | 2,500 mg|
Recent clinical studies suggest that betaine supplementation triggers a significant muscle growth response. This response is independent of testosterone and is significantly advantageous alongside typical supplementation protocols.
Betaine supplementation has also been shown to:
PreSeries BULK contains 2,500 mg of betaine anhydrous per serving.
*(PreSeries BULK does not contain any form of creatine, as caffeine negates its absorption when taken in synchrony)
|Taurine | 1,300 mg|
Taurine is an amino acid that is essential to pre-workout supplementation. Taurine competitively interacts with beta-alanine; thus, supplementation with beta-alanine and without taurine can lead to states of taurine deficiency .
Additionally, taurine used alongside BCAAs, has been found to reduce next-day muscle soreness more than either taken independently .
PreSeries BULK contains 1,300 mg (1.3 grams) of Taurine per serving.
|L-Tyrosine | 1,000 mg|
L-tyrosine is the acetylated version of the amino acid L-tyrosine. The acetylation improves the absorption and effective period of L-tyrosine, as well as optimizes the effectiveness of the energy and focus ingredients in PreSeries BULK.
PreSeries BULK contains 1000 mg of L-tyrosine per serving.
|AlphaSize® Alpha-GPC | 300 mg|
AlphaSize® is a patented form of alpha-glycerylphosphorylcholine (GPC), a highly bioavailable source of choline. Choline is an essential B vitamin that the body uses to create acetylcholine and phosphatidylcholine, both of which play important roles in cognitive function and neurotransmission. Several human studies show that alpha-GPC increases mental performance and physical performance, especially when taken in conjunction with caffeine , . Hence, alpha-GPC has both nootropic and ergogenic properties, making it ideal as a pre-workout ingredient.
PreSeries BULK contains 300 mg of Choline Bitartrate per serving.
|PurCaf® Organic Caffeine | 200 mg|
PreSeries BULK contains all-natural caffeine sourced from organic green coffee beans. Caffeine, along with many of the complimenting stimulants and focus-enhancing ingredients in PreSeries BULK are clinically proven to reduce the sensation of effort. Approximately 200 mg of caffeine has been found and confirmed to significantly increase repetitions to failure and readiness to invest effort in athletes [22, 23].
Moderate doses of caffeine have also been found to not negatively interfere with natural thermoregulation like higher (300 mg+) caffeine-infused pre workouts do .
|L-Theanine | 200 mg|
L-theanine is an amino acid used by the body. When combined with caffeine, L-theanine demonstrates many benefits for athletes, like:
PreSeries BULK contains 200 mg of L-Theanine per serving.
|Theobromine | 50 mg|
Theobromine is the primary alkaloid found in cocoa beans, and is essentially the “little brother” of caffeine. Its functions in the body are suggested to be complementary to those of caffeine, acting as a phosphodiesterase inhibitor and central nervous system stimulant . Research has also found that theobromine has differential contributions to mood and cognitive function when compared to caffeine, providing further insight into the distinct, yet synergistic nature of these naturally occurring stimulants .
PreSeries BULK contains 50 mg of Theobromine per serving.
|SenActiv® | 500 mg|
SenActiv® is a patented combination of two adaptogenic extracts: Panax notoginseng root and the more familiar rose hips (Rosa roxburghii). The notoginseng in SenActiv is highly concentrated in notoginsenoside R1, a beneficial compound that helps accelerate muscle recovery during/after intense exercise. Likewise, the rose hips provide several ginsenoside-like molecules that confer synergistic recovery-enhancing effects with ginsenoside R1 .
The distinguished adaptogens in SenActiv are suggested to work by bolstering a cellular process known as autophagy, particularly in skeletal muscle cells [34, 35, 36]. This serves as a bona fide "cleansing" of damaged organelles and structures within cells, and those components can then be recycled to make new molecules essential to cellular homeostasis. Hence, the resultant cellular damage from intense exercise requires efficient autophagic coordination for optimal recovery, and that's precisely where SenActiv comes into play.
|BioPerine® Black Pepper Fruit Extract | 5 mg||Piperine, the primary bioactive constituent in black pepper (Piper nigrum), is known as a “bioenhancer” that improves the bioavailability of molecules that are typically poorly absorbed or extensively metabolized in the liver [37, 38]. Hence, patented BioPerine® assists with the absorption and efficacy of other active ingredients in Preseries BULK.|
