A: 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.
Q: How does PreSeries LEAN compare to other pre-workouts?
A: 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.
Q: I am subjected to drug testing for my sport, can I take PreSeries Pre-Workout?
A: 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.
Q: Why doesn't PreSeries LEAN contain creatine?
A: Large doses of caffeine negates the ergogenic effects of creatine. PreSeries LEAN contains 180 mg of caffeine anhydrous.
Q: What is the difference between PreSeries BULK, PreSeries LEAN, and PreSeries STIM-FREE?
A: 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.
Q: I don't live in the United States, can I still buy PreSeries LEAN?

|Citrulline Malate 2:1 | 6,000 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 LEAN contains 6,000 mg (6 grams) of citrulline malate per serving.
|Beta-Alanine | 2,000 mg|
A majority of pre-workout supplements contain beta-alanine, but at significantly underdosed levels. Supplementing with proper dosing, as found in PreSeries LEAN, is shown to:
PreSeries LEAN contains 2,000 mg (2 grams) of beta-alanine per serving.
|BCAA 2:1:1 | (Instantized) (Fermented) 2,500 mg|
The "2:1:1" refers to the ratio of leucine, isoleucine, and valine (in that order). So, for every 2,000 mg of leucine, there are 1,000 mg of isoleucine and valine.
Leucine is the first branched-chain amino acid and is considered to be the most anabolic amino acid and is known for its strong activation of mTOR, the gene responsible for protein synthesis.
PreSeries LEAN contains 1,250 mg (1.25 grams) of leucine per serving.
PreSeries LEAN contains 625 mg (.625 gram) of isoleucine per serving.
Valine, the third branched-chain amino acid, is essential in pre-workout supplementation due to its involvement in metabolism and muscle growth. It also helps to reduce tryptophan build up in the brain during workouts. This allows for greater energy and endurance while working out.
PreSeries LEAN contains 625 mg (.625 gram) of isoleucine per serving.
|BetaPure™ Betaine Anhydrous | 1,500 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 LEAN contains 1,500 mg of betaine anhydrous per serving.
*(PreSeries LEAN does not contain any form of creatine, as caffeine negates its absorption when taken in synchrony)
|Acetyl L-Carnitine HCl | 630 mg|
ALCAR is a bioavailable form of L-carnitine readily absorbed across the blood-brain barrier. L-carnitine is an essential molecule required to transport fatty acids across the mitochondrial membrane in cells. In other words, it is a bona fide “vehicle” that carries fats into mitochondria so they can be converted to chemical energy (ATP). Recent evidence suggests that ALCAR also upregulates dopamine receptor expression and protects against neurodegeneration .
PreSeries LEAN contains 639 mg of Acetyl L-Carnitine per serving.
|Choline Bitartrate | 500 mg|
|L-Theanine | 360 mg|
L-theanine is an amino acid used by the body. When combined with caffeine, L-theanine demonstrates many benefits for athletes, like:
PreSeries LEAN contains 360 mg of L-Theanine per serving.
|Caffeine Anhydrous | 180 mg|
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 180 mg of caffeine has been found and confirmed to significantly increase repetitions to failure and readiness to invest effort in athletes [7, 8].
Moderate doses of caffeine have also been found to not negatively interfere with natural thermoregulation like higher (300 mg+) caffeine-infused pre workouts do .
PreSeries LEAN contains 180 mg of Caffeine Anhydrous 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 (4). 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 (5).
PreSeries LEAN contains 50 mg of Theobromine per serving.
|Infinergy™ (Dicaffeine Malate) | 40 mg|
Infinergy™ is a trademarked caffeine salt of malic acid (dicaffeine malate) that was created to prolong the ergogenic effects of caffeine. Rather than the abbreviated “high” and subsequent crash people often experience after drinking a large cup of coffee, Infinergy™ provides a smoother and longer-lasting increase in mental performance and thermogenesis, all without the jitters and crashing from ordinary caffeine.
PreSeries LEAN contains 40 mg of Infinergy™ (Dicaffeine Malate) per serving.
|BioPerine® | 5 mg|
BioPerine® is a patented extract obtained from black pepper fruits (Piper nigrum) standardized minimum to 95% Piperine. BioPerine® may be co-administered with various nutrients to enhance their bioavailability in both human and animal. In general, BioPerine® was found to enhance absorption of nutrients by at least 30%.
PreSeries LEAN contains 5 mg of BioPerine® per serving.
