With 100% formula transparency, proven nitric oxide boosters, hard-hitting nootropics, natural testosterone-supporting ingredients, and muscle fortifiers, this pre-workout powder goes above and beyond to meet the demands of dedicated athletes, gym-goers, and bodybuilders. Each scoop of BULK BLACK packs over 17 grams of active ingredients dosed according to clinical research and scientific evidence so you can bring the noise every time you enter the trenches. Experience intense muscle pumps, improved strength, lasting endurance, and a psychotropic rush that lifts your mood, focus, and drive for hours on end without jitters or the dreaded post-workout crash. Like all of our pre-workout formulas, BULK BLACK contains absolutely no artificial sweeteners, flavors, food dyes, or added sugars. This is as “clean” as a clean pre-workout gets.
Citrulline Malate 2:1 | 8,000mg
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:
- Improve strength, aerobic performance, and muscle endurance [1,2]
- Be at least twice as effective as L-arginine supplementation at raising nitric oxide 
- Participate in the Krebs Cycle and enhance creatine re-activation between sets (malate in citrulline malate 
- Enhance the use of branch chain amino acids like leucine during exercise 
PreSeries BULK BLACK contains 8,000 mg (8 grams) of citrulline malate per serving.
Beta-Alanine | 4,000mg
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:
- Delay the onset of neuromuscular fatigue in men and women during intense exercise 
- Increase overall muscle strength 
- Improved muscle endurance and total work done 
- Provide a tingling sensation, which can be more aggressive (depending on tolerance), which is normal and safe 
- Reduce and combat the formation of altered proteins and promote the formation of healthy proteins 
- Significantly increase lean mass and decrease fat in wrestlers 
PreSeries BULK BLACK contains 4,000 mg (4 grams) of beta-alanine per serving.
BetaPure Betaine Anhydrous | 2,500mg
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:
- Reduce fatigue when taken before and during weight training [14, 15].
- Enhance phosphocreatine replenishment between sets when creatine is taken daily *.
- Increases total repetitions and volume on the bench press exercise versus placebo .
PreSeries BULK BLACK 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 | 1,300mg
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 BLACK contains 1,300 mg (1.3 grams) of Taurine per serving.
L-Tyrosine | 1,000mg
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.
- L-tyrosine reduces the effects of stress and allows for greater mental focus and endurance .
- L-tyrosine improves memory and performance in bodily stressing climates, such as the cold .
- Believed to counteract the hypothyroid promoting conditions associated with extensive exercise.
PreSeries BULK BLACK contains 1000 mg of L-tyrosine per serving.
AlphaSize Alpha-GPC | 300mg
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 BLACK contains 300 mg of Choline Bitartrate per serving.
Caffeine Anhydrous 275mg
Caffeine, along with many of the complementing focus-enhancing ingredients in PreSeries BULK BLACK are clinically proven to reduce perceived effort when training. A dose of 2 to 4 mg of caffeine per kg of bodyweight has been shown to significantly increase repetitions to failure and readiness to invest effort in athletes [30, 31].
PreSeries BULK BLACK contains 275 mg of Caffeine Anhydrous per serving.
How To Use
Take one half (½) scoop, mixed with 8-10 ounces of water 20-30 minutes before training to determine tolerance. If increased intensity is desired, take one (1) level scoop mixed with 10-12 ounces of water 20-30 minutes before training. Do not exceed 2 scoops per day.
