Axe & Sledge L-CITRULLINE
L-Citrulline enhances training by increasing nitric oxide production, improving blood flow, endurance, and muscle pumps while helping reduce fatigue during intense workouts.*

How to use
As a dietary supplement, mix 1 scoop (5g) with 8-10 oz of water. For best results, consume daily.
Ingredients
L-citrulline is a naturally occurring amino acid that helps boost nitric oxide production in the body, increasing blood flow to working muscles. During training, this means better pumps, improved nutrient and oxygen delivery, and enhanced endurance so you can push harder for longer. It also helps reduce fatigue and supports faster recovery by assisting in the removal of metabolic waste like ammonia, keeping your performance strong set after set.
L-Citrulline aids muscle recovery primarily by improving blood flow and supporting the removal of metabolic waste. Enhanced circulation delivers more oxygen and nutrients to fatigued muscles, while helping flush out byproducts like ammonia and lactic acid that contribute to soreness and fatigue. This combination helps reduce post-workout discomfort, accelerates recovery, and prepares muscles for the next training session.*
L-Citrulline helps increase blood flow by serving as a precursor to L-arginine, an amino acid that the body uses to produce nitric oxide (NO). Nitric oxide relaxes and dilates blood vessels, a process called vasodilation, which allows more oxygen- and nutrient-rich blood to reach working muscles. This enhanced circulation not only improves endurance and strength during workouts but also supports better muscle pumps and faster recovery.*
L-Citrulline enhances endurance by increasing nitric oxide production, which improves blood flow and oxygen delivery to working muscles. Better oxygen and nutrient supply delays the onset of fatigue, supports sustained muscle contractions, and helps clear metabolic waste like ammonia, allowing you to perform longer and more efficiently during high-intensity or prolonged exercise.*
