Whatever your fitness goal, training style, or sport of choice, XTEND can help you train harder, recover faster, and get back in the game sooner.

XTEND Original also contains a unique blend of hydrating electrolytes and additional performance ingredients to help you refuel, repair, and recover. The three BCAAs are leucine, isoleucine, and valine. It’s important to note that many BCAA formulas contain only 5 grams of BCAAs per serving, which means they may lack enough leucine to effectively stimulate muscle protein synthesis (MPS).
