L-Citrulline is converted into arginine, which your body uses to produce nitric oxide. That is the blood-flow connection that makes citrulline a familiar ingredient in pump-focused formulas.*

This standalone powder lets you choose L-Citrulline without adding a complete pre-workout blend. Each scoop provides 5 g, and the unflavored format fits easily into the drink you already enjoy.

Use it to keep your ingredients separate and your routine flexible. The 500 g tub contains 100 servings.

L-Citrulline FAQ

Still deciding? Email info@darklabsofficial.com and a real person will answer.

Why is L-Citrulline used in pump formulas?
Your body converts it into arginine, which is used to make nitric oxide. Nitric oxide helps blood vessels relax. That pathway is why citrulline is commonly chosen for pump-focused routines.*
Why choose a standalone powder?
You can keep your citrulline separate from other ingredients and fit it into a drink you already use. This product is unflavored and lists 5 g L-Citrulline per scoop.
