Product insights

  • L-Citrulline enhances nitric oxide production to promote blood flow to working muscles, leading to a greater pump and improved endurance during training sessions.
  • CarnoSyn® Beta-Alanine supports carnosine levels in muscle tissue, buffering pH to resist fatigue and increase perceived time to exhaustion during intense exercise.
  • Alpha GPC supports cognitive function and focus during workouts by promoting acetylcholine production, a neurotransmitter crucial for memory and muscle control.
  • L-Theanine paired with natural caffeine from coffee bean provides clean, sustained energy and enhanced focus without the jitters or crash commonly associated with pre-workout supplements.

Suggested use

From the manufacturer
Mix 2 scoops with at least 12 ounces of water or preferred beverage daily. Consume 15-30 minutes before your workout or as recommended by your health-care practitioner.

The research

4 cited studies
1.
L-Citrulline and Nitric Oxide Production

Research demonstrates that L-citrulline supplementation enhances nitric oxide synthesis, improving blood flow, exercise performance, and recovery.

2.
Beta-Alanine and Exercise Capacity

Studies show that beta-alanine supplementation increases muscle carnosine levels, buffering intramuscular pH and improving high-intensity exercise performance and time to exhaustion.

3.
Alpha GPC and Cognitive Function

Alpha GPC has been shown to support cognitive function and enhance focus by increasing acetylcholine levels in the brain.

4.
L-Theanine and Caffeine Synergy

Research indicates that combining L-theanine with caffeine improves attention, task switching, and alertness while reducing the negative side effects of caffeine alone.
