OPTIMUM TRUE STRENGTH

From the raw materials we source to our state-of-the-art manufacturing processes, no compromises are made.

QUALITY

There are times when you want a hefty dose of caffeine for pre-workout performance. But on other occasions, like first thing in the morning or a late afternoon pick-me-up, what you’d get from a cup of coffee is more appropriate. ON’s Essential Amino Energy™ offers the best of both with a formula that delivers 100mg of caffeine from natural sources per 2-scoop serving. Decrease or increase the energy level as the occasion demands. Each serving provides 5 grams of micronized amino acids.

I read the reviews before ordering and now I have been using this product for a week. I found the reviews in general were spot on. I don't even use pre-workout when I am taking this amino energy and I'm getting great workouts

While certain flavors are amazing, it seems some flavors just do not work with the side-tastes of the amino/energy mix. The aftertaste works well with sweeter, more harsh flavors like Blue Raspberry or Grape, but not that well with smoother flavors like Cotton Candy or Coffee. Those are the only 4 flavors I've tried so far, kinda disappointing that I ended up not really liking the second two.

Amino Acids are my #1 go-to supplement. When I return to training from a long break, do high intensity, or endurance training I get very sore. BCAAs noticeably help me recover. My introduction to Amino's were ON's BCAA capsules then I moved on to BSN's AminoX; finally I tried ON's AmiN.O. Energy (this product) and it is my go to energy/amino supplement. Tastes delicious, does the job, and provides a decent kick. I've completely cut out Soda's and Energy drinks using nothing but this product and unsweetened carbonated water. Can't wait to try several other flavors.

I have tried a lot of these, its a great mid-afternoon pick me up. A lot of the flavors are decent, with the best being grape, strawberry lime and orange cooler. The only one that is not good is the Natural Raspberry lemonade, I could not even finish the first serving. It is seriously very bad.

We have been using the watermelon flavor for years, mainly because it is the only one in the 65 serving size that does not have dye. The mocha is fantastic mixed with coffee. The blueberry, compared to the watermelon, gets a 1 simply because of the flavor and consistency due to the amount of added dye. ON - all of my pre-workouts and the Modern BCAA we take use no dyes - figure it out.

Old is always Gold. Even after so many years of this product launching, rarely some of products can match up with this. If you add some extra BCAA with its serving, results will be more better.
