Directions: take half to one scoop, mixed with 8-10 ounces of water 20-30 minutes before training. L-tyrosine improves memory and performance in bodily stressing climates, and it is believed to counteract the hypothyroid promoting conditions associated with extensive exercise.
It helps to reduce tryptophan build-up in the brain and allows for greater energy and endurance. We chose citrulline malate over l-arginine because it provides better absorption, aerobic performance, higher plasma arginine levels, and has been found to: Improve strength, and muscle endurance. Most pre-workout supplements contain beta-alanine but at significantly underdosed levels. Isoleucine aids metabolism during workouts and executes anti-catabolism effects.

Ingredients: citrulline malate, theobromine, beta-alanine, infinergy, caffeine anhydrous, Betaine Anhydrous, Alpha-GPC300, Astragin, L-Tyrosine, taurine1, BCAA 2:1:1, L-Theanine, 300 mg. Long-lasting mental focus & allows for greater mental focus & endurance.
Most pre-workout supplements contain beta-alanine but at significantly underdosed levels. Isoleucine aids metabolism during workouts and executes anti-catabolism effects. This response is independent of testosterone. Citrulline malate is the “star child'' of pre-workout science. Greater energy & endurance with bcaa: valine is essential in pre-workout supplementation due to its involvement in metabolism and muscle growth. Safety warning: not intended for persons under the age of 18.

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. L-tyrosine reduces the effects of stress and allows for greater mental focus and endurance.

Improve strength & better absorption: citrulline malate is the “star child” of pre-workout science. Greater energy & endurance with bcaa: valine is essential in pre-workout supplementation due to its involvement in metabolism and muscle growth. Betaine supplementation has also been shown to: Reduce fatigue when taken before and during weight training.
Be at least twice as effective as L-arginine supplementation at raising nitric oxide. In a recent study, betaine was found to significantly increase IGF-1, while decreasing cortisol in bodybuilding men. Increases total repetitions and volume on the bench press exercise versus placebo. Lean mass & increased cellular carnosine levels: beta-alanine increases cellular carnosine levels, which are quickly depleted during intense exercise. Leucine is a strong activation of the gene responsible for protein synthesis which significantly increases strength and prevents muscle degradation while preserving lean mass.

Lean mass and increased cellular carnosine levels: beta-alanine increases cellular carnosine levels, which are quickly depleted during intense exercise.
Made with natural ingredient: gluten-free, No Artificial Coloring, No Artificial Sweeteners, no artificial sweeteners, non-gMO, no Creatine and No Artificial Preservatives. Muscle growth and decrease cortisol: clinical studies suggest that betaine supplementation triggers a significant muscle growth response. In a recent study, betaine was found to significantly increase IGF-1, while decreasing cortisol in bodybuilding men. Most pre-workout supplements contain beta-alanine but at significantly underdosed levels.

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. Studies have shown that l-citrulline supplementation 4, 000 - 6, both of which are conducive to enhanced athletic performance, 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. Ingredients: l-citrulline, caffeine anhydrous, Vitamin B6 as Pyridoxine HCl, Theobromine, infinergy dicaffeine malate, Vitamin B12 as Methylcobalamin, Infinergy Dicaffeine Malate.
