Category creating unique formula that delivers caffeine from natural source with essential amino acids and it all comes in refreshing fruit flavors. Taste-Energy-Focus-Recovery & all with Zero Sugar, you can now have it ALL!

Review: Superb product - Great for muscle recovery after workout. But it won't build muscle on it's own, need to combine with good protein diet for that. Also good option for replacing sugared drinks/fruit juice if you have cravings for them. This is at least sugar free and gives a slight caffeine kik. Taste is awesome, doesn't feel much like a suppliment. Thats what the premium price is for. I have tried orange and pineapple flavour, both are good. I liked pineapple more as it feels more natural but availability for that lesser. Hope more flavours will be available in future.

## Available Options

This product comes in different **Flavor** options.

## Questions & Answers

**Q: What is the best flavor?**
A: I really liked the Strawberry-Lime, it reminds me of a slushy as well. You will have to swirl it around the bottle as it has some sediment type stuff that may settle if left undisturbed. Still good though.Edit to add, there is another Amino from the same company the PRO version, has more aminos and no stimulants, only comes in 2 flavors though, not the same as these.

**Q: Best flavor**
A: Watermelon and Grape are the best. Orange and Pineapple were good, not great.

**Q: Do you take this instead of muscletech whey for example.**
A: Muscletech whey is a protein. Amino Energy doesn't contain protein, it's used for an energy boost pre, during or post workout. So you'd use them in conjunction with each other.

**Q: is there any artificial colors and sweeteners?**
A: Yes, natural and artificial sweeteners, sucralose (splenda), and phenylalanine.

### ⭐⭐⭐⭐ There are better options for that(whey protein
*by R***V on 17 November 2017*

This is my replacement for all soft drinks/cofee. Wakes me up from afternoon slumber. Using just 1 scoop is enough for that. Not gonna use it as pre- or post-workout drink. Not an essential product to buy for muscle gain. There are better options for that(whey protein.. & whole food is always better.. eggs, chicken breast, even soy). Lots of myths around this concept of pre- & post-workout meal/supplements. People seem to think ingredients in their post-workout meal is directly going to their muscle. Doesn't work exactly like that.
