Designed for intra-workout consumption and proven effective at promoting greater fat loss and muscle gain in two separate university studies, when used in combination with exercise, XTEND™ remains the most advanced product of its kind.

XTEND™ is formulated with a precise PentActive blend of the following ingredients that are synergistically involved in several key cellular processes†:

1. BCAAs Leucine, Isoleucine, and Valine, in a research-validated 2:1:1 ratio, to stimulate and support muscle protein synthesis and provide metabolic energy during exercise.

2. Glutamine to promote muscle intracellular BCAA metabolism down the correct energy and protein synthesis pathways via the BCAA aminotransferase enzyme.

3. The rate-limiting cofactor Vitamin B6 to ensure optimal BCAA aminotransferase reactions.

4. Bonded Citrulline-Malate to help facilitate rapid ATP turnover and lactate reabsorption to support higher training volumes at a given exercise intensity.
