Apr 25, 2017 PreSeries LEAN by Transparent Labs: When to Use Lean vs BULK?
Transparent Labs PreSeries Lean is a pre workout supplement with a few extra fat burning ingredients than the BULK version. We compare on PricePlow!
PreSeries LEAN was developed for a single purpose - to be the most exceptional "cutting" pre-workout supplement available for men and women alike. The key ingredients, citrulline malate, beta-alanine, betaine, and branched-chain amino acids (to name a few), are all included at clinically effective dosages and contain zero colored dyes, unnecessary fillers, or harmful additives.
With 100% formula transparency and a potent Fat Burning and Thyroid Support complex, which includes Chromium Picolinate and Zinc, PreSeries LEAN is most effective for those looking to target stubborn fat, while simultaneously focusing on preventing lean muscle loss.
There's a reason PreSeries LEAN comes in jumbo-sized jugs! Each serving exceeds 15 grams and includes 21 active ingredients synergistically designed to provide a high-intensity pre-workout experience, while focusing systematically on fat loss and additional energy expenditure.
Serving Size: 1 Scoop (16.14g)
Servings Per Container: 30
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 LEAN contains 6,000 mg (6 grams) of citrulline malate per serving.Beta-Alanine 2,000 mg
Supplementing with beta-alanine has been proven to increase cellular carnosine levels, which are quickly depleted during intense exercise [28, 29].
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 [ba1]
- Improved muscle endurance and total work done [ba2]
- 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 
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.
- Leucine has been found to significantly increase strength during workouts .
- Metabolites of leucine have been found to prevent muscle degradation and preserve lean mass .
PreSeries LEAN contains 1,250 mg (1.25 grams) of leucine per serving.
Isoleucine is one of the three branched-chain amino acids, which aids metabolism during workout, promotes muscle growth, and executes anti-catabolism effects [48, 49, 50].
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 valine 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:
- Reduce fatigue when taken before and during weight training [34, 35].
- Enhance phosphocreatine replenishment between sets when creatine is taken daily *.
- Increases total repetitions and volume on the bench press exercise versus placebo .
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
PreSeries LEAN contains 630 mg (.630 grams) of Acetyl L-Carnitine HCl per serving.Choline Birtartrate 500 mg
PreSeries LEAN contains 500 mg of Choline Birtartrate per serving.L-Theanine360 mg
L-theanine is an amino acid used by the body. When combined with caffeine, L-theanine demonstrates many benefits for athletes, like:
- Increases reaction time, attention, and memory [14, 15, 16, 17]
- Reduces jitters in caffeine sensitive individuals
- Reduces stress and causes relaxation without affecting attention and energy .
PreSeries LEAN contains 360 mg of L-Theanine per serving.Caffeine Anhydrous180 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.Theobromine50 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.Thyroid Support Complex 2,495 mcg
Iodine (as Iodine Chelate)
Iodine is the primary mineral required in the thyroid's production of metabolism fueling thyroid hormones.
PreSeries LEAN contains 225 mcg of Iodine (as Iodine Chelate) per serving.
Zinc (as Zinc AAC)
Zinc supplementation is essential to any aggressive athlete and contributes to a strong immune system, maximal testosterone production, and extensive enzymatic processes.
Sufficient zinc intake supports healthy food cravings, while zinc deficiencies have been associated with lack of hunger . Overwhelming evidence has suggested a relationship between zinc supplementation and maximal testosterone levels in men [45, 46, 47].
PreSeries LEAN contains 30 mg of Zinc (as Copper AAC) per serving.
Selenium (as L-Selenomethionine)
Selenium supplementation aids metabolism by promoting muscular uptake of carbohydrates which aids individuals with underactive thyroid symptoms .
PreSeries LEAN contains 50 mcg of Selenium (as L-Selenomethionine) per serving.
Copper (as Copper AAC)
Copper supplementation is advantageous as a coenzyme for the conversion of iodine to biologically bound iodine.
PreSeries LEAN contains 1 mg of Copper (as Copper AAC)
