There’s a noticeable difference in my soreness when I’m not on this product. There's a reason I’ve used this product for eight years!

It Works!

I am a newer CrossFit member but sometimes bike and run. I started Extreme Endurance 3 weeks leading up to a sprint triathlon. With little training I somehow pulled off 1st AG and 20th female overall. I’m a believer!

Hi Joyce,

Great job! Congratulations on your success!

Fastest 5k I've run in years!

Ran almost 2 minutes faster this year on the same course I ran a year ago. Thanks!

Hi Jeff,

So far so good

Been taking Xendurance for a week and have noticed that I can eke out a couple extra reps on most all sets. I plan to keep taking it to see if gains continue.

Hi Rick,

Thanks for the feedback! We're happy to hear that Xendurance is helping you improve your workout performance. Keep up the good work!

Feel great!

Started taking almost 2 weeks ago and already feel better during and especially after training. Definitely recommend for BJJ athletes.

Haven’t really vent anything yet

Not sure if I’m too old for this to work (41) but I haven’t felt anything yet. I was hoping to get a little extra on my mountain bike rides or morning runs…. I’m about 2 weeks in, I’ll finish the bag and keep my fingers crossed

We appreciate all feedback but can we ask if you drink a lot of coffee, or juices or eat red meat? Did you chew or swallow the tablets? If you would like more feedback please email and we will get back to you with some impute on what may help you! Thank you!
