I agree with the other comments stating that we are a long time users and *something* changed with the Grape flavor May 2020. It lacks flavor, so I returned 2 assuming it was a bad batch, as they were the same batch number. I bought more in August and November, but the same results. Very sad as this was our favorite. PLEASE look into what was changed and go back!! We have been searching for a new alternative with no luck.

Peach Lemonade is the best supplement flavor I have ever had. It's refreshing in the summer and gives me a good amount of energy as a quick pick me up, or as a pre-workout. - BBCOM employee

How can anyone in his right mind call this "strawberry burst" flavour good I dont know, but the effect is good so It wouldnt be fair to give a lower rating. Delivery was faster that estimated.

Strawberry burst is amazing it is a little sour but has an amazing flavor. Orange cooler is my 2nd favorite it’s just a great classic orange flavor. Blue raspberry is awesome and flavor is what you would expect. Cotton candy flavor is less intense than others I have tried but tastes great. Fruit fusion was really weird and I got a strong watermelon taste from it instead of a fruit punch like I was expecting by far my least favorite.

I love Amino Energy! My husband and I have drank it for years. We've tried so many flavors but the above listed have become our "Tried and Trues"....and something *changed* with the Concord Grape. I used to love it! Last time I purchased it and loved it was probably summer 2020. In November 2020, I purchased it and the flavor was way different. I am not sure if it was just a bad batch, but I'm scared to buy it again. Hope ON changes the formula back! Watermelon is my all time favorite. It's absolute perfection. Orange is a close second. Only reason it's 9/10 is because it seems like a much stronger dye and I wish they'd take the food dyes out. I always wonder if it's doing that to my bottle, what's it doing to my teeth. I also love strawberry lime! It's especially good if you put some fresh lime juice in it.

I did the recommended Pre-workout 4-6 scoops and didn't feel any energy boost when it came time for my workout.

Cotton Candy is solid. Tastes better than the Bang or Reign cotton candy drinks. Juicy Strawberry Burst is good...but **** it is SWEET. I am not sure if Cotton Candy is just more tame (I drink it with about 8oz water), but I have to put almost 2x the recommended 10-12oz of water just to be able to drink this flavor. Delicious flavor, but **** the first time I tried it with 10oz of water it was so tart! Will be trying a different flavor soon. If I find that they all are that sweet, I will modify my review to a 10 (if you can do that).

Where is the Cafe Series flavors??? Please make these available again! These are the best, especially the vanilla. I'll need to look elsewhere if you don't bring these back. It looks like I'm not the only one with this strong opinion.

WHY!? Why would Optimum Nutrition remove the Café Series flavors? The Iced Mocha Cappuccino Amino Energy mixed perfectly with the Chocolate flavored Gold Standard 100% Whey protein. PLEASE BRING THE CAFÉ SERIES FLAVORS BACK.
