A deeper look at the ingredients in Advanced Pre-Workout

Alpha-GPC

Alpha-GPC is a choline compound found in the brain and supports the body’s production of the neurotransmitter acetylcholine, helping to maximize the mental aspects of your performance.*

  • Promotes focus and memory*
  • Enhances power output during explosive exercise*
  • Promotes physical endurance so you can train and compete at your best*
  • Helps maintain the body’s natural production of human growth hormone, essential for recovery*   

CarnoSyn® Beta-Alanine

Beta-alanine is an amino acid that plays a crucial role in supporting carnosine levels, which efficiently buffers the pH of muscle tissues without excessive lactic acid buildup.*

  • Supports muscle pH to resist fatigue and delayed onset muscle soreness*
  • Increases perceived time to exhaustion*
  • Promotes VO2 max, enhancing cardiovascular fitness*

L-Citrulline  

L-citrulline is a non-essential amino acid that supports the synthesis of nitric oxide more effectively than other amino acids with similar functions.

  • Enhances nitric oxide production*
  • Promotes blood flow to working muscles, leading to a greater “pump”* 
  • Supports endurance efforts*
  • Enhances overall recovery through increased blood flow*   

L-Theanine

Almost exclusively found in the tea plant, L-theanine is an amino acid that enhances key neurotransmitters involved in mood, focus, and memory.*

  • Enhances performance and accuracy when combined with caffeine*
  • Helps limit the “jitters” and crashes normally associated with pre-workout supplements*
  • Creates a relaxed, yet alert state of mind*
  • Supports the body’s ability to resist fatigue*

Because athletes need to know their supplements are trustworthy and compliant, every batch of an NSF Certified for Sport® product is tested for compliance with label claims and to ensure the absence of nearly 300 substances banned by many major athletic organizations.
