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.*

The Xtend profile is simply awesome. 7g BCAAs versus most others 5g -0 I like to hit 3g leucine and this does it in one scoop. adding glutamine is so very helpful and they don't neglect the electrolyte mix. This is an awesome intraworkout and recovery drink. The flavors are wonderful - all of the ones I tried are better in comparison than most other brands I've tried of the same - and not weak at all, which is my biggest gripe about some amino drinks as I like things full-flavored. I was even able to increase the amount of water and the flavor still holds. It's also some of the easiest to mix, ever. I thought and have to go back and shake it up after settling but there simply was none. My only wish for improvement is possibly the dyes, and if they could move away from ace-k. but you don't drink massive amounts all day, so for the quality overall, I'd recommend.

First off if you've never had Xtend, stop reading this right now and order a tub. Any flavor they're all delicious. Now onto my experience. I've had many flavors of Xtend and have enjoyed them all and drink it intraworkout for almost every gym session. This time I'll be reviewing Fruit Punch, Watermelon, Mango and Grape. (In my experience all Xtend flavors have perfect mixability (just a few quick shakes) the price point for the quality is unbeatable, ingredients are top of the line, and the effects are, in my opinion, minimal but worthwhile so for the readers sake I will discuss flavor) I dislike fruit punch a lot. I had a bad experience with a fruit punch flavored creatine in the past from a different company so I stay away from that flavor at all costs. With that being said this is delicious. Throw a few ice cubes in your shaker and it is so refreshing. I would continue to buy this flavor again and again. I personally am not a fan of watermelon flavored products so I was skeptical at first. My 7 flavor rating is a tad biased since I don't like watermelon to begin with but it was good. I had 24 oz of water to one scoop of Xtend so the flavor was diluted a little but I did enjoy it. A little less water and the flavor would really shine. Mango Xtend is the only flavor of any product I've ever tried that tasted juicy. It's hard for me to really explain it any better but it was like I was drinking actual mango juice and it was incredible. The only bad part of this flavor was eventually I ran out. Will 100% have to get more because this is incredible and you can see many will agree on here. Grape straight up tasted like grape koolaid. No other way to describe it. This is just mouthwatering delicious. It's the one flavor I've wanted to try for so long and finally was able to get my hands on some and I promise this stuff is a game changer. Hopefully my reviews were vivid enough for you to help you decide which flavor to choose but really you can't go wrong. Scivation doesn't know how to make a bad product or a flavor that isn't delicious!

When I started heavy lifting, I hadn't been physically active in a long time. Even after 3 months of careful and well planned exercise and dietary changes (with plenty of complete proteins), I was still debilitatingly sore with the worst DOMS you can get. It took all of 3 days for this product to bring my muscle soreness down to a normal and manageable level. My gains also started to increase rapidly within a month. I'm hesitant to attribute such a massive change to one product, but if I miss a dose, the severe DOMS comes right back. Two years on and I will never stop using it. I take 4 doses a day rather than 2 since I find it works more effectively. I can't recommend it highly enough!

Performance: just like the other flavors of Xtend, this performs perfectly. Keeps me hydrated and provides plenty if the aminos I need to get me through any day (even hurricane Irma currently pounding my house!). Taste: This flavor is my hero. Years ago I got burned out on a certain sport drinks kiwi strawberry and I thought I would never enjoy that flavor again. Xtend fixed that! This flavor is strong and refreshing with just the right balance of strawberry (most strawberry kiwi flavors are way too weak on strawberry, but not this one!). If you haven't had it yet, try this one, you won't regret it!

This is one of the best BCAA products on the market and never disappoints! It includes electrolytes, proper amino ratio, added glutamine, and citrulline malate. Xtend is very affordable compared to other products and they even have sales to make it an even lower price quite frequently. The powder mixes perfectly and doesn't leave extra residue or powder on the shaker. It comes in a ton of flavors to cater to anyone's taste preferences. There is even an unflavored option that is natural without any dyes, etc. and can be added to anything. Compared to not taking this product I noticed increased recovery and less fatigue while working out. I mix it with 15-20 oz of water and it tastes perfect, less water increases the flavor so be sure to experiment with the water amount. The fruit punch is one of the best fruit punch flavors i've had and reminds me of kool-aid. The watermelon also tastes great and reminds me of a jolly rancher, it's not too sweet or sour. I would recommend this to anyone looking to increase recovery in a delicious way!
