Quite possibly my new favorite!

This is an honest and true review of this item, which I purchased full price on Amazon.com: I have been using Amino energy for over a year now and it is very helpful with no adverse reactions (personal experience, your results may vary). I work night shift, this has been a great substitute to coffee or canned verity of energy drinks. Drinking coffee at night tends to give me heartburn, so I began looking for other options. I have been using other Optimum nutrition products for over 10 years and have always been pleased. When using this product I have plenty of energy throughout the night with no crash and when I get home,= and I can fall asleep easily. I have tried all the flavors this is by far one of my top 5's! The Apple flavor is spot on to a green apple jolly rancher, I mean...IDENTICAL! My favorite flavors are as follows.. blueberry lemonade, strawberry limeade, green apple, grape, watermelon. I personally think they should get rid of the coffee and tea flavors..not good. There is nothing I would change about this product, I recommend to everyone.

I like it! I was afraid to try pre-workout for ...

I like it! I was afraid to try pre-workout for a long time, but this brand is very good. I take 1-2 scoops before my afternoon workout, depending on how I'm feeling, and always have a "better" time, whether it's cardio or lifting. I don't get the jitters or have sleep issues (even when taking it at 5-6 pm), it doesn't hurt my stomach, and it tastes pretty good.

Highly recommend

I started using this to help me get through my workouts as it's been a while since I had a regular routine. It blends well in water and tastes nice. Plus in about an hour I get a huge boost of energy that makes me feel invincible lol. It makes a huge difference in my workouts. I do notice it takes a while to leave my system which means I can't take it after 4pm or it will be 10pm and I'm still feeling the effects. I'm very sensitive to caffeine and stimulants. Overall I recommend this and would order again.

Great Product, Some Flavors Better Than Others

I’ve been using Optimum Nutrition Amino Energy for 3 years now, my wife for 1 year. I drink this during the second half of my workouts & bike rides. For workouts, I mix a serving (2 scoops) in a 16oz bottle of water. For bike rides, I add a serving to my 20oz water bottle. My wife mixes 1 serving in a 16oz bottle of water to drink after her runs. We both agree, ON Amino Energy helps us recover from our workouts. For the most part their flavors are all pretty good, some definitely better than others. My wife thinks the Green Apple flavor is “ok”. It’s not her favorite, but it’s drinkable. I’m not a big fan of this flavor. It’s a bit intense for my taste. It won’t keep us from buying it in the future, as we like to vary flavors. My wife really likes the Watermelon & I have to agree w/her. The Peach Lemonade is a favorite of mine, she thinks it’s “ok”. Her favorite flavor is Strawberry.

Great energy provider but container is only half full

I use this product as a pre-work out, and it gives a great amount of energy. The watermelon flavor also tastes great, like a jolly rancher. My only complaint is that my container was filled only half way. Its already a smaller sized container, so I was disappointed that it was only half filled.

Go To

ON is quickly becoming my go to brand for my workout and fitness! I have five of the Amino Energy now and I love them all! The grape with collagen is the one I like mixing with others to combine flavors since I am not a huge grape person. It still tastes really good though and I love the added benefit of the collagen. Strawberry burst tastes exactly like a pink starburst. It is so good! I love using this before and during my workout. Cotton Candy smells exactly like cotton candy. It has a blueberry cotton candy flavor. I really like it! Watermelon is ok for a pre, but I am not a huge fan of the flavor to sip on but it is more my flavor profile liking. It still tastes amazing! Pineapple is really good too. It is more subtle with the flavoring than some of the others. I have also dry scooped some of these for a pre-workout. I like them both ways! I do not think you can go wrong with taste on any of them!

Authentic!

I was a bit nervous after ordering this item, I read through the reviews and saw a ton of people saying they received a package that didn’t have a seal, or was poorly sealed, and was a completely different product than the one directly from ON. I figured worst case scenario I have to send it back... When my package arrived I was pleasantly surprised as the product had the factory seal, beyond that the freshness seal was tight, and the product inside seems to be the real deal. Im not sure if it’s hit or miss or if this is something Amazon has become aware of or changed, but for around $10 you can’t beat it. The flavor is amazing and it provides a good kick of energy for a workout or just to get you through the day. 5 stars from me and I will continue to order until I have a problem.

night and day difference

I used to get super sore after working out, and I could barely get through the workout itself. With this supplement, I have improved the amount of minutes I spend jogging and I can get through my gym classes without feeling like I will keel over or there's an alien trying to come out of my chest. I am so happy I discovered this. I am not a pro-athlete, just a regular person trying to get in better shape.

Apple Pre Workout- Great!

I have thus far tried this flavor as well as the grape. I can say that I prefer apple much more. Like most pre-workouts I have tried, there is a distinct vitamin taste, but that is to be expected (because.....it's basically vitamins....). Like the other amino energy I've tried, this gives me a great boost for pre- or post-workout without getting a case of the jitters. You can get even more of a boost by adding more scoops, and the plastic container gives you a range to go by. Mixes very nicely in water; I've had no chunks whatsoever. All in all a great item, I will be trying more flavors in the future.

My Daily

I have never been a coffee drinker but I imagine that my daily dose of Amino is to me as coffee is to so many others. It gives me a nice boost everyday, before and during my workout. I originally started drinking this to help with muscle recovery and it does. I have been drinking this for well over a year and I drink it every morning. I notice the difference when I don't. When I don't drink it, I have little less energy and achy muscles. I've tried a few different flavors but the watermelon is, by far, my favorite. I definitely recommend the product.
