Build and preserve muscle with 7 GRAMS of hypercritical BCAAs — in the nature-designed and widely-researched 2:1:1 ratio — along with Glutamine and Citrulline Malate. Plus, with a proprietary blend of hydration-promoting electrolytes, Scivation XTEND is the delicious, refreshing, SUGAR-FREE way to help anyone grind through a grueling gym session.*

Perfect Before, After, and During Training

World-class athletes, elite bodybuilders, champion powerlifters, and weight-training enthusiasts of varying types all use Scivation XTEND during their workouts to help them train longer, harder, and with more intensity.* When consuming two servings daily, Scivation XTEND helps to facilitate both fat loss* and new muscle construction.* Also, by orchestrating optimal protein synthesis and by balancing the intracellular energy economy, Scivation XTEND severely truncates recovery time.*

Branched Chain Amino Acids, Not Just Essential Amino Acids

Scivation XTEND contains 7grams of branched-chain amino acids per serving. No hiding, no tricks, no "padding" from cheap or completely random amino acids. Each serving of Scivation XTEND contains 3.5 grams of Leucine to stimulate muscle protein synthesis plus 1.75 grams of Valine and 1.75 grams of Isoleucine.*

2:1:1 Ratio Designed by Nature, Proven by Research

Nearly all of the reputable peer-reviewed studies that have highlighted the effectiveness of BCAAs — along with most of the anecdotal information that has sprung forth from the hardcore weight rooms — have investigated a 2:1:1 Leucine to Valine to Isoleucine formula. So despite a starring role for Leucine, Valine and Isoleucine are still vitally important to a multitude of the physique benefits that come from BCAAs.

One noteworthy study investigated muscle protein synthesis from either Leucine on its own or from BCAAs at a 2:1:1 ratio. College-age, recreationally-trained male participants received a straight Leucine supplement, a 2:1:1 BCAA supplement, or a non-caloric placebo before and after a leg workout. As to be expected, Leucine performed better than did the placebo, but the 2:1:1 BCAA ratio bested them both.

Valine & Isoleucine - Vitally Important as Well

Additionally, in an attempt to dazzle you with numbers, some lopsided amino formulas drop the amounts of Valine and Isoleucine in favor or Leucine - a critical mistake - which ends up smothering some other very important benefits. For one, Valine competes with Tryptophan for uptake into the brain, and a brain soaked in Tryptophan will have a much hard time relaying the message to the muscles that they need to work harder and push more weight. Furthermore, in a Japanese study, scientists observed a fat-burning mechanism dependent upon Isoleucine. Subjects who consumed more supplemental Isoleucine gained less body fat than those who did not, even though both groups ate a high-fat diet.

So when it comes to getting the most out of your workouts, whether it be triggering post-workout muscle protein synthesis, thwarting fatigue, or stoking the fat-burning flames, a 2:1:1 BCAA ratio — the same ratio in Scivation XTEND — is the way to go.*

After 10 Years, Still Defining - and Redefining - BCAAs

Scivation XTEND, the originator and leader in BCAA technology, is the trusted brand credited with creating the first BCAA intra-workout drink mix.

Scivation Xtend BCAAs have been my trusted intra-workout drink. The flavors I've tried so far are really delicious! It's super refreshing at the same time it's not too sweet (no sugar at all). BCAA ratio is ok as well (though I believe higher Leucine content is better). When I drink this during my Training Sessions, I experience more energy, better focus, faster recovery and less muscle soreness post-workoutl. I usually take 2-3 scoops for every 2-3hr Training Session, and then another 1-2 scoops to be consumed throughout the day (I treat it like fresh "juice"). I highly highly recommend this product, really effective and satisfying as well.

Green apple is bomb. Unsure about the pineapple. It has a weird flavor. Almost too sweet.

  • 10 Blue Raspberry

The flavor of the blue raspberry is awesome!

The grape flavor tastes pretty good but honestly mango is not what you expect .

Tangerine is the best flavor but I don't think it's available anymore. Tastes just like the drink mix Tang. Blue Raspberry is great. Really notice the endurance benefits while sipping on it during my workouts. Solid product.

  • 7 Green Apple
  • 2 Pink Lemonade

I absolutely love the effects of this product. This is by far my favorite BCAA mix compared to others that I have tried. I always add a little more water than it calls for just because the flavors are a bit overbearing, but my gosh, the pink lemonade is absolutely disgusting. Green apple, not bad just really strong.

This is a great product if you are not looking for stimulants (like BCAA Energy and Amino Energy)! However the two flavors I tried were extremely bitter I could not even force myself to drink the lemon lime.

  • 7 Green Apple
  • 8 Blue Raspberry
  • 8 Blood Orange

Great product, awesome flavors! This has more BCAA's per serving than most of it's competitors with a few extra additives such as the electrolyte blend. Would highly recommend!

  • 1 RAW - Unflavored

The "unflavored" version is terrible. It has an awful bitter taste you will likely not be able to stomach. You must mix it into a smoothie or shake to disguise the taste. Forget drinking it from a shaker cup.

Been using Xtend for awhile (years...), pretty standard BCAA supplement, mixes great, normally tastes great. I personally observe reduced fatigue on long workouts (versus without BCAAs). My recent pineapple flavor was terrible. Typically a sweetener masks the taste of the salt in the product, but that does not seem to occur with the pineapple flavor, nor does it taste anything like pineapple. If you're doing a lot of heavy lifting and/or have a long workout, it may be better to forgo the BCAA supplement and/or include a carbohydrate supplement instead.
