Get ready for take off!
I use AltRed for all of my hard workouts and long runs. I'm a marathoner. I've had my fastest and strongest marathons since taking AltRed. I go into every marathon with confidence knowing AltRed will allow me to finish strong! It's quite unbelievable how well this stuff works. I feel like superman with AltRed!

I was skeptical...
When it comes to supplements, I'm skeptical. And so that's definitely how I approached AltRed when I was given some to try before going out cycling. I wondered if I'd feel some kind of energy boost after taking them, similar to an energy gel, but AltRed doesn't have that sort of an impact. Instead, I found myself pushing a higher average over the course of my ride and having an overall higher watt output for the ride. Then, post-ride, I didn't experience my usual leg fatigue that comes after a good cycling workout.

Happy with results
Recently started taking this during my long training runs - I've found that I am holding a faster pace with easier effort, and, I'm not as sore after (I run hilly routes for my long runs). So, I'm satisfied with my purchase. Also, I LOVE the tiny little capsule container that comes with the bottle. Very easy to carry extras during those training sessions.

Immediate Results and Beyond High Expectation
My wife and I ordered AltRed and decided to use it about 90 minutes before a 27 mile ride. The difference, especially for my wife was profound. We're casual riders on road bikes. But she had no trouble in staying on pace for the entire 27 mile ride. At about mile 20 she said to me... "I'm a believer!" That's after one pill 90 minutes before the ride. And she hasn't tired throughout the day as would typically be the case. We can't wait to continue to use AltRed to enhance our rides.
