A very good product
As you would expect from such a reputable company, another great product. It gave me a nice little energy boots before hitting the gym with no horrible side effects. There is a slight taste to it nothing to over powering much like a cheap own brand squash palatable is the best way to describe it. The powder mixes easily with water (9mg to 330ml) it is as with most of O.Ns range expensive, but you do get what you pay for, yes there are cheaper alternatives, but if cost isn't something you have to worry about this is for you.

Great pre run drink
This is my favourite pre run drink. Tried a few others but there were that many calories in them it was messing up my macros - as amino energy comes in around just 30 calories I’ve got it burned off in no time. At one point I started to wonder if it really worked or if it drinking it was just habit so did a few runs without it......could really tell the difference so now I make sure I never run out. Not so keen on the orange flavour but it’s still drinkable (i’ll generally buy whichever is cheapest when I’m ready to order).

Tastes great
I wanted a preworkout to give me energy for gym workout and cardio that wasnt as insane as jack3d or craze and that I could take as an everyday pick me up. I'd also read about the benefits of taking amino's for fitness so this powder seemed to fit the bill. First off i took 4 scoops half an hour before my workout on an empty stomach, 15 mins later i could feel the beta alanine buzz, i had a pleasant buzz giving me that extra energy for weighted circuits followed by some short cardio. I didn't feel any crash like some other products even though the buzz was short. I've since drank amino energy in a smaller dose before a night out, enjoying this product as a great alternative to coffee. The only negative is how quickly I have gone through the tub, if you plan to take it as a preworkout then at 5-6 scoops at a time, it will be gone pretty quick. But as a break from concentrated preworkouts this is a great product.

the product gives results
I really like this product, My gym instructor, recommended it to me., my workouts are really good, with shiftwork it's hard to train. I can do two hours of high intensity. My muscle recovered well, I didn't get muscle fatigue, really good product, I believe I reach my fitness goal. but don't rely on it, it's a support product. you still mentally need work hard.

Don't love the flavour - not 100% sure about this product yet...
Fit For Purpose I bought this product to give me an extra kick of energy at the end of a long day at work before going to the gym as I often feel tired/drained after working all day. I opted for optimum nutrition because I am aware that it is a good brand. I have never had a pre workout before so I didn't want to spend too much money which is why I went for the orange flavour (it was one of the cheaper flavours at the time). I think this was a mistake on my part because I am not too keen on this flavour at all which has put me off using it too often. It is perfectly fine to drink and it is not in any way horrible to taste but I just think I would have enjoyed other flavours more. As for its effects as a pre workout, I am not wholly convinced. I do not feel as though it really gives me any more energy than a piece of fruit or a strong green tea. My boyfriend has suggested having it first thing in the morning before having eaten anything else as he thinks it is more effective on an empty stomach! So at the moment the jury is still out on this I am afraid. Packaging Came extremely well packaged to prevent any damage to the product. Delivery Delivery was fast & free. Value for money Great for the money as you only need a small scoop per serving so this will last for ages! I think my boyfriend's lasts him over 3 months & he has it 5-6 times per week. Will I purchase again? Not sure yet but if I do I will try another flavour. Please hit 'Yes' if you found this review helpful :)

First, I am not a body builder, but I do workout hard and a lot. I have found this product helps with muscle recovery. This is due to many of the amino acids in the product which are part of the AMIN.O. ENERGY name. Here's the gist of the ingredients per serving size which is 2 small scoops (9 grams): Amino Acids: Taurine, Glutamine, Arginine, Leucine, Beta Alanine, Citrulline, Valine, and more... Energy Stuff: Caffeine, Green Tea Extract, Green Coffee Extract (Not all the amino acids are used for recovery. For example, arginine/citrulline are used for nitric oxide production -- the N.O. in the name.) I see a lot of reviews on the other flavors of this product saying it did not give the intense workout compared to some other products. I might surmise that it is because this is more of an "all purpose" product targeted to many sports. One thing it doesn't have is creatine which I consider a must-have as a pre-weight lifting supplement. So, if you use this as such, you should consider adding a creatine (or kre-alkalyn) supplement. I see it's main competitor as Scivation's Xtend, which is a very good product as well. The cost, the serving size, the recommended usage/doses, even the bottle are similarly shaped. One main difference is that Xtend is all recovery amino acids (10 grams) while the AMIN.O. ENERGY has less than half that amount because of the other "stuff". Because of that, the recovery benefits are not as good. So, the other stuff in AMIN.O. ENERGY makes it more all-purpose but less focused. If you are not weight lifting, then you probably don't want the creatine anyway. With the other "stuff", it makes a good (but not great) all-purpose * pre-exercise, * endurance, and * recovery supplement. If you lift weights and use another pre-workout drink (for example, I really like the Cytosport Fast Twitch which includes creatine and some of the other "stuff" as well), then many of the non-recovery amino acid ingredients are redundant. Also, the caffeine (100mg per serving) makes it less suitable for a late evening (after work) supplement. What I have found is that AMIN.O. ENERGY makes a great energy drink a couple times during the day. It also use it as an in-between recovery booster. Then, I use Xtend as a more focused recovery product when I workout (along with other more focused products). Another difference between this and Xtend is that this dissolves vastly more easily than Xtend. It is realistic to dissolve this in a glass of cold water in a couple minutes whereas Xtend will take 1 or 2 days. Dissolving Xtend in even hot water is not easy. So, this one is much easier to make a quick pick-me-up energy drink (at only 10 calories, too). Finally, I think the taste of the orange is really good. I have used full containers of all three flavors: orange, grape, and fruit, but this one is the best partly because the amino acids are a bit on the bitter side, and this hides it better than the other flavors. I also use this to mix with CytoSport's Fast Twitch lemonade which, by itself, tastes pretty fair and is caffeine-free. That gives me a good-tasting supercharged pre-workout drink. My only gripe (no star deductions) is that the price of this can vary wildly, so pay attention. You can also get it on other sites cheaper at times. The price is very volatile.

ON products tend to be on the pricier side but this is still great value. Useful for training or leisure purposes, not too sweet either.
