I was curious what this compound was used for exactly?
		
		
	 
Google directed me to an article on a site I used to rep for:

What is Citrulline Malate?[/h] Citrulline Malate combines the amino acid citrulline with malate, an  organic salt. It plays a role in numerous biochemical reactions within  muscle tissue.

Why Should I Take It?[/h] If you’re looking to increase performance capacity in the gym or when  you train, Citrulline Malate is believed to positively impact a number  of key biological processes, including:
 
Reducing Lactic Acid and Ammonia Buildup.
 When we train – whether we run, lift heavy weights, or attack a spin  class – our bodies produce ammonia and other toxic by-products. A  build-up of these by-products leads to a reduction in athletic  performance. Step forward, 
Citrulline Malate.  It plays an important role in the Urea Cycle, helping to eliminate  these by-products, increasing your ability to maintain performance and  fight off muscle fatigue.
 
Greater Nitric Oxide Production.
 Supplementation of Citrulline Malate is shown to increase Arginine  levels in the body, which supports the production of Nitric Oxide. This  in turn has benefits like increasing blood flow, oxygen transportation  and nutrient uptake, as well as assisting muscle functions for improved  output and growth.
 
Supports the ATP System for Prolonged Output.
 It is believed that supplementing with Citrulline Malate can also  assist athletes by increasing aerobic energy production – allowing you  to reach higher endurance thresholds. There is also evidence of improved  phosphocreatine recovery, post-exercise.

When should I take it?[/h] Citrulline Malate is best taken on an empty stomach for optimal  absorption. On exercise days we would recommend taking one serving first  thing in the morning and another serving 30-40 minutes prior to  exercise.

How much should I take?[/h] We recommend taking 3.0g-5.0g per serving, 1-2 times daily. A BULK  POWDERS™ 5ml measure (level scoop) provides approximately 2.6g of  Citrulline Malate powder. We therefore recommend using 1-2 scoops per  serving depending on your preference.
