For those who think these products sold on iHerb are fake, you are completely WRONG. I have been buying Optimum Nutrition for years and iHerb carries and sells products by the manufacturer.Now for the product - I mix this product with the Optimum Nutrition Collagen + Hyaluronic Acid in the Watermelon Citrus flavor and it taste amazing. I use the combination of this product every day - even on days I do not workout.I highly recommend all of these products and have seen and felt the difference these products have made on my daily fitness life style.(If my review has helped in anyway please be sure to click "Helpful" "Like" so more people can see it.

While I have been a distance runner for most of my life, I began training for half marathons just last year (2019). I also had never consumed any special sports or athlete-specialized foods or drinks other than Gatorade and Powerade. This is why I was excited to try the Essential Amino Energy Blueberry Lemonade powder. I wanted to see if it made a difference in my stamina. Most of the time I drank the "mild" dose of 2 scoops for an "afternoon pick-me-up" and that worked great. It definitely gave me enough energy to stay alert through the afternoon. I played around with my post-workout dosage. Depending on how many miles I ran, I would use the 4 scoop "moderate" dose or the 6 scoop "intense" after my longer runs.

I would love to try strawberry or raspberry flavors if they are available! The only negative critic I have is that it doesn't seem to dissolve very well. I really had to stir it to get rid of the pockets of powder stuck in the fizzy bubbles it created.

Surprisingly potent and yet MILD energy boost that works without making you shake or causing anxiety or any other nasty side effect that typically occur from the OTC stimulants. It even has a mood enhancing effect although mild, but pleasant.Unlike coffee, it doesnāt imbalance your blood sugar levels and doesnāt overstimulate the CNS in any caffeine like manner: Iām sure you know what I mean if you ever drank coffee āļø - lol.Iām reordering a few more .The taste is a predictable chemical nastiness, but it is impossible to make energy powdered drinks taste any better, so it is all about the effect really. So, I donāt think itās a negative- just expected.Thereās only ONE thing that I find to be poorly thought through: packaging.The size of the container is ...Ā MoreSurprisingly potent and yet MILD energy boost that works without making you shake or causing anxiety or any other nasty side effect that typically occur from the OTC stimulants.

its an amazing product truly I have tried almost all the flavorsall of them are acceptable and super like them unlike other brandsgreen applegrapesorangewatermelonpineapplenow I'm going to try the lemon lime which I think it will be amazing because I like sour thingsI'm going to write a review about it once it reachthe product is great for recovery after a long run or after intervals specially in summer which its very hot in my country100% works and with great tastehighly recommend
I enjoy the kick a good glass of pre-workout gives me, and really appreciate it when it is not overly-priced. The peach lemonade version from ON Nutrition fits that description. The amount is enough for a couple months of use and the taste of each flavor is good. I have bought several of the flavors, and while this isn't my favorite of the roughly dozen flavors, it is good.
I have been purchasing the optimum 100 whey goldstandard protein from Sportsfuel when a deal popped up that included the optimum amino energy sampler. I needed to get some more whey any way, so never one to turn down a good dea!? I got the sampler and trialled when best to take it; before workout, after workout; with mixed results, however with only a few servings left I tried it during my workouts, as part of my hydration. The difference for me was startling, it improved my energy levels and focus during my workouts something chronic. For me, I sometimes struggle at the start of a workout to get "into it", with this stuff, that problem no longer exists. Although the the grape flavour may not be to everyone's taste, I find it really refreshing.

The amino energy powder mixes really well and I haven't had any issues with lumps or clumping in any of the concoction I have made with it. Everyone will have different results and like me I would trial what and when's the best time to take it, but for me this will become a permanent addition to my supplement regime, thanks Sportsfuel.
This product works great for someone who wants an energy boosts before workouts but doesnāt enjoy the traditional side effects associated with pre-workouts. I have tried a variety of brands and pre-workouts over the years but had trouble becoming loyal to one product.

Iāve now been consistently using Essential Amino Energy for about half a year and never felt the need to stray. By evaluating it on its: effectiveness, taste, and price, I regard it as the best value pre-workouts Iāve encountered.EffectivenessAs a pre-workout, this provides consistent energy without bringing on the twitching sensation that many other pre-workouts are known to. It tends to be most effective when drank about 30 minutes before starting a workout. The caffeine kicks in subtly, giving you gradual sensation of focus and heightened awareness. So by the time youāre starting to workout, you get that āin the zoneā mentality a lot of people look for in a pre-workout. The effects of a regular serving tend to wear off within 1-2 hours. The lower dosage of caffeine makes it easier to come down from if youāre someone who works out at night and doesnāt want to have trouble falling asleep.TasteWhile the energy and amino acids provided is effective, itās the taste of this product that impressed me the most. Other pre-workouts can have a very artificially sweet taste that is hard to enjoy. Someone with a sensitive stomach like myself may also find that this doesnāt give them a stomach ache like other pre-workouts might. While Iāve only tried three flavors, Iāve enjoyed all of them.Peach Tea:Someone who has a sweet tooth would likely enjoy this one as it tastes exactly like a gummy peach candy.Blueberry Mojito:This is also very candy-like, with a similar taste to a cotton candy sucker.Pineapple:This flavor is not as strong as the other two, as it provides a more subtle tangy taste. Itād be a good option for someone who doesnāt prefer things too sweet.PriceCompared to other pre-workouts, this is likely one of the least expensive youāll find. Other pre-workouts tend to cost around 30 to 40 dollars compared to 19 dollars for this. The fact that it also doubles as a dosage of amino acids only adds to its value.Overall, this would be a good option for someone new to taking energy supplements for working out, or just someone who doesnāt enjoy the effects of traditional, highly-caffeinated pre-workouts.
I'm giving this 3 stars because while it tastes great and is easy to use I didn't notice enough of an increase in energy for my workouts as I would have liked.Pros:It tastes great. I personally love fruity flavors and blue raspberry is a favorite of mine.It mixes very easily. I used 3 scoops and then put in 3-4oz of very warm water, swish it around for a couple seconds, and then add ice cubes and 8oz cold water. No grit and no clumps. Again, I really enjoyed the taste - it was like drinking a treat, almost felt like an indulgence for me.Cons:Overall, I just wasn't impressed with the level of energy I got from it. I followed the instructions and drank it 20-30 minutes before a work out. I do a rotation of HIIT workouts one day and then strength training the ...Ā MoreI'm giving this 3 stars because while it tastes great and is easy to use I didn't notice enough of an increase in energy for my workouts as I would have liked.Pros:It tastes great.

I followed the instructions and drank it 20-30 minutes before a work out. I do a rotation of HIIT workouts one day and then strength training the next. It suggested starting out with 2 scoops and adjusting from there. I noticed nothing with 2, went to 3 and felt slightly more energy than I had with 2. Perhaps if I experimented with 4 or more scoops I would notice a more significant increase but I'm hesitant to have that much caffeine in a day since I am a religious 3 cups a day coffee drinker.Bottom line is I wouldn't purchase this or recommend to a friend. It may be I'm just not the best fit for a product like this but it didn't give me enough of a performance improvement to warrant a purchase of this product.
I enjoy essential amino energy very much-the grape flavor. I use it alone w/water and mix it w/grape pre-workout powders for added help when working out. I have used it during the work day and can drink less coffee due to this great product. I have not experienced any jitters or anything negative when using it. Keep it coming, GNC! Thanks. - A repeat customer
Absolutely LOVE the grape optimum nutrition amino pre-workout. If it didn't have the caffeine, I would drink it as water! It gives me the boost I need to either work out harder (heavier or longer) or stay up and do chores. And the amino make it even healthier in my opinion. I used to buy the same product in cans, but I prefer the powder more. If you are on the fence of trying it, don't hesitate and BUY IT! You will not regret it.
