Ready-to-drink & calorie-free, XTEND RTD delivers more BCAAs than 25 grams of whey protein, and refreshes hard-working muscles with electrolytes, Taurine and Citruline Malate, making XTEND RTD the convenient and muscle-supporting BCAA solution.*


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. With over a decade devoted to improving and perfecting the formula – best-in-class flavors, show-stopping mixability, and fully-disclosed ingredients in relevant amounts – Scivation XTEND continues to outpace comparison. There's nothing like it.

Use Scivation XTEND, the original and most widely-used intra-workout BCAA product, to build muscle, burn fat, and to prolong the intensity of - and recovery from - your next workout.*

These are the best BCAA's I have tried and they don't have that dry sour flavor some of the others do & it isn't overly sweet like some that I have tried. The Mango is seriously delicious! So glad that I tried these!

  • 7 Mango
  • 10 Blood Orange
  • 7 Watermelon
  • 8 Blue Raspberry
  • 8 Strawberry Mango
  • 7 Pink Lemonade
  • 8 Grape
  • 9 Green Apple

After trying Pink Lemonade, I received Xtend (Green Apple) from Scivation through a weekly promotion. This product is awesome! BCAAs are a staple in my diet. Lately, even if I'm not drinking them intraworkout you can catch me drinking them throughout the day. I love the ingredient profile and I love that you get 7g of BCAA per scoop. I always look for a good ratio. The label tells you this, but this product has a 2:1:1 ratio (Leucine: Isoleucine:Valine). In addition to that, each scoop has added electrolytes along with glutamine and citrulline! So you stay hydrated, you have glutamine to recover even faster, and you have citrulline to help you with endurance.I love that there is no added "fluff." What you see, is what you get in this product. As far as flavors go, the pink lemonade is pretty good, but the green apple flavor is great! The pink lemonade has a slight aftertaste, but it's not bad once you get used to it. I definitely plan to keep Xtend in stock and I'm aiming to try Blood Orange next. (Edit: I just got my Blood Orange in! Can't rate it on here for some reason... Maybe because it's out of stock. I give it a 10/10! Wow! That stuff is good!). Update as of August 16, 2017: Since writing this original review, I have tried several additional flavors. I really do love what Scivation has going for them here. I will continue to use Xtend, and as long as they continue to produce new flavors, I will keep trying them out. (There are two other flavors not listed on here that I have tried. I give Pina Colada an 8 out of 10, and I give Margarita a 7 out of 10.)

Mixability: Just like all other flavors of Xtend, this one mixes great. Barely anything left at the bottom and if you make a big flask of it to drink thru ought the day like I do, eventually the little residue disappears as well. Taste: I know, this is what you are all here for, lol So, one of my all time favorite flavors is the Mango and I wanted to know how this compares. They are neck and neck. The Pineapple is refreshing and light, while still having a fresh pineapple taste. It's not quite like drinking pineapple juice, it's more like the taste you get when you bite into a slice of fresh pineapple. Tip: mix 50% mango, 25% tangerine, and 25% pineapple. Oh yeah. Performance: Performs just like the other flavors, fantastic. I sip on some all day and at the gym. I know that's a little excessive, but it keeps me drinking water and its still cheaper than sodas. In short: Are you drinking some pineapple xtend right now? If not, go buy some. If you are, then go buy more, you might run out soon.

Like how easy it mixes up and how it tastes. I drink 2-3 a day and like how it helps recover time.

  • 7 Blue Raspberry
  • 9 Mango

This is the Ultimate BCAA and intra work-out drink.. I have been using this product for 120 days of 4 months from the date of review. This is the... THE G-D of all BCAA's. Tried many others, few worked some failed. But this always did its job. You can feel the energy still after 1 hour of cardio and 2 hours of Weight room training , the replenished feeling and spot on recovery. Zero Calories, Glutamine, 2:1:1 spot on and medically veried BCAA ratios. The REAL GOD of BCAA's. My personal rating is 12 out of 10. Just Fantastic. Just amazing.
