L-Citrulline is one of the most effective supplements for boosting muscle pumps. It works by increasing nitric oxide levels, which relaxes blood vessels and improves blood flow to your muscles.
More blood flow means more oxygen, more nutrients, and a fuller, tighter pump during your workout. It also helps delay fatigue by improving circulation and clearing waste buildup.
Unlike L-Arginine, L-Citrulline is better absorbed, making it more effective for performance and pumps.
A typical dose is 6–8g before training.
Simple, reliable, and it works.
