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!

A New Staple In My Regimen!!

I started using this about 3 weeks ago. I initially did the 7 day challenge and noticed my stamina/endurance had improved significantly. I was able to go longer/harder during my training routine and had a higher than normal calorie burn.

Since then I've noticed an improvement in both my cardio and weight training sessions. My recovery is improving and I am setting new PR (personal records) every time I walk into the gym.

This will definitely be a supplement I continue to use in my routine going forward.

Had my doubts about the effectiveness of a singular supplement. However this supplement has been crucial for recovery (especially putting in 60+ miles and 3-4 strength workouts a week) It used to take multiple days to recover from a hardcore speed workout. Now I’m recovered same day or at least by my run the next morning. Incredible.

Love this supplement!

I have virtually no soreness. I recover much faster, my VO2max has improved, and performance is much better. I will be buying more and become a member.

The Review of all reviews

As I was taking my last 3 tabs this morning I thought, “ I gave it my best shot, and I haven’t felt any real difference in my training, definitely nothing that would motivate me to re-order” I go for my run (8miles) it was only suppose to be 6, but I was feeling pretty good. Afterwards, I checked my stats and my VO2 increased! 🥳 I had been working on this… it seems like forever. So not only have I re-ordered, I’m a member! 💪

Awesome! Thank you for taking the time to share your success with our Extreme Endurance product. We're thrilled to hear that our product has made a difference in your training and helped improve your VO2 levels. We always aim to provide top-notch results for our customers, and we're so happy to have you as a member. Keep pushing to the extreme!

Better recovery

I’ve only taken this about 10 days. I have noticed less overall soreness. I’ve been building mileage the past 2 weeks so I’m still sore and tired, but I think I’m recovering better. I have not noticed any improvement in stamina while training yet.

Thank you for sharing your experience with Extreme Endurance! As you continue to build your mileage, we hope that our product will continue to help you recover better. While stamina improvements may take some time to notice, we are confident that you will see results in your training soon. Keep up the great work!

Great product. New increases in FTP!

I was hesitant at first but gave Extreme Endurance a try. I took it consistantly and started see a shift upwards in FTP in about 3 weeks. It has also helped greatly with recovery. I'm a believer and a happy customer!

Thanks for choosing Extreme Endurance! We're thrilled to hear that you finally gave it a try and are seeing such incredible results in such a short time. We hope you continue to see great improvements with our product. Keep pushing to the extreme!
