Great Product!
- Great taste?.
- The fruit punch taste in very distinct with 10oz of water.
- The fruit punch taste is creamy tasting with 24oz, which is very interesting, yet very good.
- Strong muscle pumps
- The ½ scoop serving size is more than enough for my training sessions and body weight of 189 lbs( 6' 2" bodybuilder/athletic build).
- Dissolves very well.

love it!
Just tried out this bcaa in the fruit punch explosion flavour and love it! I use it intra-workout or during cardio and especially like how it has Peak ATP in the formula, citrulline and glutamine making it perfect for recovery and strength.

Fresh Amino
I haven't used Amino's before in my years of training, but that was before I started a heavier cardio routine into my daily mix. After testing this product for several weeks I have found that it gives me an extra drive and dare I say pump to push on. The taste is amazing and goes down smooth without any extra grainy or sanding mix at the bottom which I love! I received this product from MuscleTech as a tester and again they continue to provide great products any fitness level. Couldn't be happier with the results!

Energizing workouts
I always had seen guys in the gym drinking shakes during their workouts and really didn't realize the reasoning behind it until I started doing it myself. I actually didn't know how helpful BCAs were either and how your body reacts in such a positive manner. I use to buy a pre workout drink to get me through the workout but after using this before and during I am hooked.

Tastes Great/extra reps
Another great product from MuscleTech. I have been taking it during my workouts. I've been doing heavy weight super sets and feel like I maintain power throughout the workout and can still hit it hard the next day. Great product.
