Second Best

I've been using Amino Energy for years. Concord Grape is my fav flavor. I was purchasing it at Costco for a bigger (72 serving vs 65) container for much cheaper but.....they don't stock it any more. Wal-Mart carried it for the best price so WA-LA

AMAZING

Love this flavor!! Was unsure at first because I am not a big grape fan, but this flavor is now my favorite. And Amino Energy works great without the big crash. Just steady energy.

Great boost before morning workout!

This is one of my top 2 flavor favorites in the Amin.o energy drink line. It takes great, and I like to drink it in the morning to give me a boost before my workout.
