Xtend is the hugely successful endurance and recovery formula from Scivation. Xtend is a great-tasting and easy-to-use drink mix powder that you sip before during or after your workout. Xtend has become popular largely through word-of-mouth testimonials but if you're not really pushing yourself in the gym, you're not the kind of athlete who's going to notice great results from Xtend - yet. That's because you're not yet operating near your performance or recovery limits. But as you progress, you'll better appreciate why Xtend is a hot product with fitness fanatics who love to train, train hard and train often. These athletes notice big improvements in endurance, sped-up muscle recovery and buffering effects against over-training. That means fewer interruptions and steadier progress. Xtend is spawning a lot of imitators but it's a proprietary (and therefore unique) blend of branch chain amino acids, glutamine, citrulline and B6 that can't be found in any other product. So get the real deal and add Xtend to your cart, not an Xtend-like product. See why Xtend picks up more fans everyday. For best taste and results, mix Xtend into very cold water and re-mix periodically as you consume each serving.
