|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 BULK contains 6,000 mg (6 grams) of citrulline malate per serving.
|Beta-Alanine | 4,000 mg|
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.
|BCAA 2:1:1 | (Instantized) (Fermented) 4,000 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 BULK contains 2,000 mg (2 grams) of leucine per serving.
PreSeries BULK contains 1,000 mg (1 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 BULK contains 1,000 mg (1 gram) of valine 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.
|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 BULK 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 BULK 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 BULK contains 50 mg of Theobromine per serving.
|Infinergy™ (Dicaffeine Malate) | 30 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 BULK contains 25 mg of Infinergy™ (Dicaffeine Malate) per serving.
|Astragin™ | 25 mg|
AstraGin™ is a novel extract of Astragalus membranaceus and Panax notoginseng — two adaptogenic herbs will longstanding history in traditional Chinese medicine . The constituents in these plants are suggested to selectively enhance the absorption of biomolecules by increasing intestinal permeability.
PreSeries BULK contains 25 mg of Astragin™ per serving.
