Just Magic

Honestly. Just buy it. You want to get faster? Buy it. You want to go further and not feel as tired? Buy it. I cheated and timed myself before taking them and less than a week later I shave more than a minute off my pace. i have a half marathon race in a week and I can’t wait to see what time I get. I don’t care if it’s a placebo effect. I will be using these forever.

Good Stuff

My husband and I were both taking it along with another friend. We all noticed less fatigue after big workouts. Unfortunately, I started to develop some digestive issues so quit using it but have no clue as if the product was the culprit. So, other two users experienced no adverse reactions. I liked the product but will try again later.

Thank you for your review! We're thrilled to hear that you've noticed an improvement in your post-workout recovery since taking Extreme Endurance. While we cannot confirm if our product was the cause of the digestive issues, we always recommend consulting with your doctor before starting any new supplement. We appreciate your feedback and hope you will give our product another try in the future.
