OPTIMUM TRUE STRENGTH

True Strength is a journey. It never rests, it never quits. It's about overcoming obstacles, accomplishing goals, and recognizing achievements. And then it resets to achieve again. As your trusted sports nutrition partner in goal achievement, ON demonstrates that same passion while crafting our products. From the raw materials we source to our state-of-the-art manufacturing processes, no compromises are made. You set the bar higher after every workout, we set the bar higher to redefine the industry standards and ensure you realize optimum results.

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've started taking this a few weeks ago. for several days i tried finding the right pre-workout because the one i was using was discontinued. i watch steve cook's youtube and i always wondered how he got so much energy during his workout and new he was sponsored by ON. so i took a shot and tried concord grape. i was very surprised. didn't get fatigued, i was pumping hard, no tingles, and didn't feel sick. used it all up quickly with 2 servings for workout and 1 for an afternoon pick-me-up. i just opened blueberry mojito this morning, same results and a pretty good taste. will defiantly buy again.

The apple and grape are my favorite. I prefer flavors that are more sour than sweet. The green apple tastes like a jolly rancher.
