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.

Recovery & Energy
I noticed most comments talked about recovery which I noticed right away. I also found the day after a race or hard workout I am often depleted in the morning, I started taking a AltRed tab when I get on non workout days and it revitalizes me for the rest of the morning. I am still trying to figure out if it is best to take it one hour or two hours before my 6 mile to 13 mile runs.

Worked amazingly
I received 10 free supplements from a challenge on Strava and took one before most of my cross country meets this year. My heart rate was noticeably less that it usually is during races while running faster than ever before. I would definitely recommend them for anyone serious about running and I would take them before every race.

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!
