Transparent Labs Bulk Pre Workout, Contains Anhydrous Caffeine, L-Citrulline, and Theobromine, Gluten-Free, Non-GMO, No Sweeteners, for Muscle Growth, Tropical Punch - 30 Servings
  • Greater Energy & Endurance with BCAA: Valine is essential in pre-workout supplementation due to its involvement in metabolism and muscle growth. It helps to reduce tryptophan build-up in the brain and allows for greater energy and endurance. Leucine is a strong activation of the gene responsible for protein synthesis which significantly increases strength and prevents muscle degradation while preserving lean mass. Isoleucine aids metabolism during workouts and executes anti-catabolism effects.
  • 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. Be at least twice as effective as L-arginine supplementation at raising nitric oxide. Enhance the use of branch chain amino acids like leucine during exercise.
  • Muscle Growth & Decrease Cortisol: Clinical studies suggest that betaine supplementation triggers a significant muscle growth response. This response is independent of testosterone. Betaine supplementation has also been shown to: Reduce fatigue when taken before and during weight training. Increases total repetitions and volume on the bench press exercise versus placebo. In a recent study, betaine was found to significantly increase IGF-1, while decreasing cortisol in bodybuilding men.
  • Delay Fatigue & increased cellular carnosine levels: Beta-Alanine increases cellular carnosine levels, which are quickly depleted during intense exercise. Most pre-workout supplements contain beta-alanine but at significantly underdosed levels. Proper dosing of STIM-FREE delays the onset of neuromuscular fatigue in men and women during intense exercise and Promotes the formation of healthy proteins Significantly increase lean mass and decrease fat in wrestlers.
  • Long-Lasting Mental Focus & Performance: Infinergy prolongs the ergogenic effects of caffeine & provides a longer-lasting increase in mental performance & thermogenesis without the jitters & crashing from ordinary caffeine. L-tyrosine reduces the effects of stress & allows for greater mental focus & endurance. L-tyrosine improves memory & performance in bodily stressing climates, & it is believed to counteract the hypothyroid promoting conditions associated with extensive exercise.

Transparent Labs Stimulant Booster Pre Workout, No Tingling, Contains Anhydrous Caffeine, L-Citrulline, and Theobromine, Gluten-Free, Non-GMO, No Sweeteners, Unflavored - 60 Servings
  • Improve Strength & Better Absorption: Upon ingestion, L-citrulline is rapidly absorbed and transported to the kidneys where it is converted to L-arginine and subsequent NO. Studies have shown that L-citrulline supplementation (4,000 - 6,000 mg per day) significantly increases oxygen uptake during intense exercise and reduces blood pressure, both of which are conducive to enhanced athletic performance, recovery, and muscle cell volumization.
  • Lasting Mental Focus: Theobromine is the primary alkaloid found in cocoa beans and is the “little brother” of caffeine. Its functions in the body are complementary to those of caffeine, acting as a phosphodiesterase inhibitor and central nervous system stimulant. Research has 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.
  • Long-Lasting Mental Performance: 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.
  • Increase Mental Focus: Caffeine is 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 Moderate doses of caffeine have also been found to not negatively interfere with natural thermoregulation like higher (300 mg+) caffeine-infused pre-workouts do.
