Optimum Nutrition 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. Essential Amin.o. 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 for muscle support.*

Consistency

Optimum Nutrition has been spotting the efforts of goal driven individuals since 1986. As one of the few companies to operate its own state-of-the-art manufacturing facilities that are GMP compliant, ON assures that every shake will mix up effortlessly because of its first-to-market instantization process. You also expect each shake to taste the same as the last and your next. That's the kind of consistency ON delivers.

History & Heritage

Optimum Nutrition is legendary for both quality and innovation. In addition to producing the world's best-selling whey protein, our Gold Standard 100% Casein™ introduced slow-digesting nighttime protein to the weight training world and ESSENTIAL AMIN.O. ENERGY™ created the anytime energy category in sports nutrition. When technology makes advancements possible, ON will be the company bringing it first to your shaker cup.

  • 8 Juicy Strawberry Burst

Cotton Candy is solid. Tastes better than the Bang or Reign cotton candy drinks. Juicy Strawberry Burst is good...but **** it is SWEET. I am not sure if Cotton Candy is just more tame (I drink it with about 8oz water), but I have to put almost 2x the recommended 10-12oz of water just to be able to drink this flavor. Delicious flavor, but **** the first time I tried it with 10oz of water it was so tart! Will be trying a different flavor soon. If I find that they all are that sweet, I will modify my review to a 10 (if you can do that).

Where is the Cafe Series flavors??? Please make these available again! These are the best, especially the vanilla. I'll need to look elsewhere if you don't bring these back. It looks like I'm not the only one with this strong opinion.

WHY!? Why would Optimum Nutrition remove the Café Series flavors? The Iced Mocha Cappuccino Amino Energy mixed perfectly with the Chocolate flavored Gold Standard 100% Whey protein. PLEASE BRING THE CAFÉ SERIES FLAVORS BACK.

  • 10 Concord Grape
  • 7 Blue Raspberry

Great product to use in the morning for energy and aminos, or as a pre-workout supplement. Very noticeable energy output when using 3 or more scoops. The recommended 2 scoops will do the job, but my preference is a little stronger. The concord grape is absolutely delicious, I love drinking it on a daily basis and don't tire of the taste. Blue Raspberry wasn't exactly great in my opinion, felt more of a blueberry juice syrup taste. Was able to drink the contents but wouldn't be my first choice when reordering.

  • 10 Juicy Strawberry Burst

This is the absolute king of pre-workouts in my opinion because of the dial-the-intensity approach, 50 mg of caffeine per scoop, that's perfect. The Juicy Strawberry flavor is frankly outstanding and is the best I've ever tried. I wish that flavor was available in larger container sizes.

Great product. Tastes great and works for what I need. If anything I wish they made Juicy Strawberry Burst in a bigger size. Never had any shipping issues with BodyBuilding.com and their customer service has always been super helpful.
