Roctane Ultra Endurance Energy Drink Mix, Vegan, Gluten-Free, Kosher, 35mg of Caffeine, and Dairy-Free n-the-Go Energy for Any Workout, 3.44-Pound Jar, Summit Tea

Great flavor options and works

I wanted to try Gu roctane but didn't want to buy it the gels. I bought this powder form and I use it before my run. The big box is very good value for money. Honestly I cannot tell the difference between Gu and Gu roctane but maybe there is a difference. The energy levels are usually high 20 minutes after drinking it. Love the Gu brand in general

I feel far less tired after long rides since I’ve been using Roctane. Can’t recommend it too highly. It’s got 250 calories, which is the same as a Cliff Bar, BCAA’s, caffeine, and of course electrolytes. Summit Tea flavor doesn’t have that fruity taste that I don’t care for at all.

It’s as good as every steamy dream you ever had as a teenage boy, it’s the summit tea my boy. Get you some. Relive the glory days in your head as you effortlessly click past the miles as easily as sipping on an iced tea at grandmas house when you were a kid.

It has improved my cycling

As someone who pushes through long runs and intense training, the GU Energy Roctane Ultra Endurance drink mix has become a staple. Each Summit Tea packet delivers a solid 250 calories of quickly absorbable carbs, a hefty 320 mg of sodium to keep hydration in check, and a powerful blend of amino acids (BCAAs plus beta-alanine) to help fend off muscle fatigue and damage. The light, refreshing taste mixes cleanly in 21 oz of water — no chalky or sugary aftertaste. It keeps me focused and energized, mile after mile. Whether you're racing or grinding through training, this is a rugged and practical go‑to energy boost that keeps you rolling strong.

This mix isn't super sweet like gells are so it is a great alternative. Got me through many 3+ hour rides and used it for 70.3 nutrition after I got sick of the GUs.

I've used nearly every brand of energy gels and powder and this is the first time my stomach got irritated every time I drink it. Could just be me, but not likely since i drink other flavors of the same brand and it doesn't happen.
