Sendure-X Beetroot + Citrulline Powder - Caffeine-Free Pre-Workout - Boosts Blood Flow, Energy, VO2 Max, Endurance, Recovery - NSF Sport Certified, Peak Performance, Natural - 30 Servings Wild Berry

Phenomenal taste, but doesn’t taste too sweet like a lot of other traditional pre-workouts do. Also never feel adverse effects such as jitters or stomach issues during my workouts or climbs which is also an issue with other brands. Takes time but you’ll notice a greater output in how much effort you can give for longer. Couldn’t recommend more, it’s the only endurance/energy output sport supplement I’ll use from here on out.

Perfect for climbing sessions! Sendure-X keeps me feeling fresh and energized without the jitters. The taste is also great and it dissolves well in water. I also really appreciate that there is no chemically flavor that you find with most other pre workout products. There really isn’t anything else on the market that can compare.

Sendure-X is my go to drink to power long endurance sessions. Whether I’m hitting the trails on my bike, climbing steep endurance routes, or stuck at home on the elliptical, Sendure-X gives me the energy to push through on hard workouts for great results. Tastes really delicious as well.

Great flavor. Tastes like black Cherry koolaid. It works well enough for a stim free product

I do Ninja and noticed that a fellow Ninja was using this while training. I asked what it was and purchased - I am so glad that I did. I am SUPER sensitive to caffeine and stimulants, and this does not make me shaky at all. It gives me just the right amount of energy to sustain longer workouts; I drink half prior to my workout, and sip the other half throughout the rest of the workout. I also appreciate that they utilize clean ingredients that I can feel good about putting into my body. I am excited to try more products from this company!

I don’t really enjoy the taste, but I suppose it works fine.

I recently tried this caffeine-free pre-workout powder, and it has certainly helped my workout routine. As someone who actively climbs, as well as incorporates weight training and long runs multiple times/week, finding a supplement that supports these activities was crucial for me. This product delivers on all fronts. First off, the boost is immediately noticeable. My energy levels are consistently high, without the crashes associated with caffeinated supplements. This is a huge plus, especially for evening workouts when I don't want my sleep to be affected. Endurance has also seen a marked improvement. During long runs, I find myself able to maintain a steady pace for much longer periods, and my VO2 max has improved. I feel more efficient and less fatigued, which has translated to better performance and faster recovery times. Overall, it has been huge for improving my training routine and allowing me to maintain energy while also speeding up recovery!

As a pro ultrarunner, I take a scoop of this plus electrolytes before every long run or speed workout and find that it makes a noticeable difference in both endurance and power output. I can go much further before I notice my muscles fatiguing, and it feels easier to “rev up” to max speed during intervals. Plus it tastes delicious and makes being well hydrated a lot easier as someone who has trouble drinking enough water on its own and gets dehydrated quickly. Gentle on the stomach, no concerns about downing a bottle of it pre-run. Genuinely will turn around and go back home to shake up a bottle with it if I realize I forgot to before heading to the trail because it helps me get so much more out of the workout. I’ve also noticed that I recover faster between hard days now that I’m taking it regularly.
