# **RULE ONE CITRULLINE – PUMP AND ENDURANCE SUPPORT**

Citrulline contributes to nitric oxide synthesis which supports muscle pumps and training performance making this amino acid a popular foundational staple for any serious lifter.

Each scoop mixes readily into all your favorite beverages and workout supplements for convenient supplement enhancement.

**HOW TO USE IT**

Mix one (1) scoop with 200-300 ml of your favorite cold beverage or pre-workout supplement. Consume before or during training. Citrulline mixes easily into sports drinks, smoothies, and fruit juices.
