Flavor Name: Lemon Lime SourSize: 45.5 oz Verified Purchase
I've been using this for about a month now and can't say enough great things about it. This product has a 2-1-1 ratio which is great and the 90 serving size gets you more for the money. I never used BCAA's when I work out and I've been doing so for the past 20 years off and on. This product gave me endurance and also aided me in recovery. My workouts for the past year have been brutal. My workout consists of using weights first then sprints to then steady state cardio. After my workout I have been completely depleted of energy and felt sluggish and sore. While using this product for the past month, I no longer had any of these issues after my workouts. As another reviewer stated, there's only 3 grams of Glutamine in this product. I add another 5 grams to get the daily recommended amount needed for recovery.

Since there's no product details on Amazon I thought I'd share that info. You're probably asking the same questions I asked myself before I decided to purchase this. What made me decide to purchase this product were the 5 star reviews.

Flavor Name: Raspberry BlueSize: 30 Servings Verified Purchase
A lot of supplements make claims about effects that are not immediately, if ever, observable. This is not one of them. When I first started taking this, I immediately noticed that I could go longer during cardio/strength oriented routines such as P90x and Insanity. I continued to drink this as my workouts evolved to running and weight lifting. Despite always being a terrible runner (I simply never felt that "runner's high", was never able to run very far, and was usually miserable) my runs, while never really increasing too far in distance, seemed to require less effort, making them more tolerable.

But the real difference, came in my weight training. Being 44 years old, I was surprised at how quickly I went up in weights, how muscular I was getting, and how little soreness I had. I've lifted weights on and off for nearly 30 years, and suddenly I was lifting, in some cases, more than I ever had. Now, full disclosure: shortly before I started using Xtend, I also began taking creatine. This absolutely resulted in a strength and muscle gain. So once I started taking Xtend, I wondered how much of my performance gains I could attribute to the creatine. I felt the cardio-related gains were definitely the result of the Xtend, but the strength gains could have been the continuing results of the creatine.

UNTIL I stopped taking Xtend. That was about a month ago, in part due to budgetary restraints and partly because I wasn't sure anymore if Xtend was really helping my time in the gym all that much. In the past month, however, the weight I lift in many of my exercises has slowly dropped, my endurance has decreased (I'm more sluggish and my workouts simply seem more daunting), and worst of all, I'm feeling my age.

Flavor Name: Green Apple Explosion!Size: 30 Servings Verified Purchase
I have tried the old formula Watermelon and the new Blue Raspberry and Green Apple.

I like the increased workout ability (strength/time) and the lessened muscle soreness. I have one serving a day on workout days and do not normally use on "rest" days. I have recommended this to my sister and cousin.

Mixes much better than the original formula.

Sweet? Oh yes, it's sweet. Mix is 1 scoop to 8oz of water. I prefer 1 scoop to 16 oz of a combo Ice/Water.

tip: Amazon normally has best pricing!

ETA: Amazon will not let me review different flavors, only one, therefore I give it 5 instead of 4 stars. All performance statements above are the same for each flavor.

BLUE RASPBERRY: Tastes like kool-aid. Totally delicious!

WATERMELON: (I have only had the older version but plan to order more in the new) Also very tasty. Like a watermelon treat.(This review on watermelon is original to March 2012).

4/4/2012: I have found a variety pack that includes 6 flavors of XTend. Orange Dream, Lemon Lime Sour, Watermelon Madness, Raspberry Blue, Green Apple, and Grape.
GRAPE: I normally do not like grape anything but tried that flavor to make my sister happy. Grape is actually very good. It does not taste like a brand name cough medication.
WATERMELON: The new Watermelon formula is TERRIBLE! It tastes like super sweet sugar free watermelon flavored candy.
ORANGE DREAM: Orange Dream is pretty good, but not my fave.
LEMON LIME SOUR: Lemon Lime Sour has a tangy taste that I didn't care for. That said- I don't like lemon lime sports drinks either.
GREEN APPLE: some people have stated this tastes like an apple candy.
