O15 Nutrition | Intra-Workout

Nutrition during training is one of the most over-looked aspects of building your desired physique. You need the perfect ratio of amino acids and carbohydrates to spare muscle tissue and provide your body with an energy source which will not elevate blood sugar levels. 

O15 Nutrition Intra-Advantage™ was designed to meet the physical demands of Mr. Olympia Brandon Curry and the rigorous training sessions he undergoes to build one of the most coveted physiques in the world.

Intra-Advantage™ features the Vegan-friendly Amino 9®, a studied and proven blend of all 9 essential amino acids, to augment your performance in the gym and boost your recovery times out of it. Along with Amino 9®, Intra-Advantage boasts two critical carbohydrate sources: Carb 10® and Beta-Cyclic-Dextrin. These prevent blood sugar spikes so you get the immediate energy benefits of carbs without the crash. 

THEN, Taurine and Electrolytes (Sodium, Calcium, Magnesium & Potassium) for cell volumization and hydration to ward off cramping.

To top it all off, Intra-Advantage™ has a delicious taste you will CRAVE! Take your workouts to the next level with the ONLY intra-workout designed by, and for, Mr. Olympia Brandon Curry!

High quality, delicious flavor!

I can always count on O15 for high quality products, this rainbow sherbet flavor is even better than I hoped it would be. I needed some intra carbs during the workouts and finally found a great product I know I can trust.

Mr O has given us an incredible intra!

I use this product on back days and on leg days to help fuel my workouts. Much more sustaining than a typical BCAA product. This is like nothing I've used before. Great taste! This is something I will be buying again and again in the future. I'm excited to see if the other flavors are as good as Rainbow Sherbet.

Great Workout Assist!

I have used BCAAs when I train for a couple decades. Intra Advantage ups the game a bit, and you can absolutely feel it on tough training days. I love the story behind the product and completely get behind their intra-workout thought. If you’re skeptical, I get it. It’s absolutely worth a try.

Best Intra-Workout On The Market

This is my second time ordering Intra Advantage from Marc Lobliner and Brandon Curry. This is hands down the best intra workout on the market. EAA's and Beta Cyclic Dextrin is exactly what you should be taking during your workout. Highly recommended!
