With 30 servings per bottle, this is one of the best values on the market for pre-workout energy - and can even be combined with your favorite pre-workouts for an added boost.

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.

  • L-tyrosine reduces the effects of stress and allows for greater mental focus and endurance [22].
  • L-tyrosine improves memory and performance in bodily stressing climates, such as the cold [23].
  • Believed to counteract the hypothyroid promoting conditions associated with extensive exercise.

PreSeries STIM-BOOSTER contains 1,000 mg of L-Tyrosine per serving.

NooLVL | 800mg

nooLVL® is a patented form of bonded arginine and silicon, with added optimized dose of inositol that increases nitric oxide production and blood flow. NooLVL® is a stim-free nootropic that works fast to deliver increased energy safely, without negatively affecting heart rate or blood pressure.

PreSeries STIM-BOOSTER contains 800 mg of NooLVL per serving.

Taurine | 500mg

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 [40].

Additionally, taurine used alongside BCAAs, has been found to reduce next-day muscle soreness more than either taken independently [39].

PreSeries STIM-BOOSTER contains 500 mg of Taurine 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 STIM-BOOSTER contains 300 mg of Alphasize® Alpha GPC) per serving.

PurCaf Organic Caffeine | 100mg

The addition of PurCaf® to the Stim-Booster formula provides a natural source of caffeine to awaken and energize your mental and physical performance when you need it most.

 PreSeries STIM-BOOSTER contains 100 mg of PurCaf® Organic Caffeine per serving.
