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*
