SciVation Xtend is a branched chain amino acid (BCAA) supplement that claims to enhance muscle endurance and recovery during intense exercise.

The product contains the already scientifically proven effective 2:1:1 ratio of BCAA's L-Leucine, L-Isoleucine and L-Valine.

In addition, Xtend has 2.5g of glutamine per serving which is added to enhance muscle recovery.

Lastly, citruline malate is included. This is a relatively new addition to the supplement market, but it has shown promise in promoting muscular endurance during anaerobic exercise.
