Guys, I have to say you might have THE most effective endurance product on the market. I've used C5 before but did little cardio while on it. I stuck to mainly weight lifting.
About a month ago, I decided to cut some weight. I did the first 2 weeks w/o Cordygen. I was gased after running 1-1.5 miles (could barely breath) I decided I needed some help. After 2 weeks back on Cordygen 5 I can honestly say I almost don't get tired running. Just today I ran 3 miles in ~28 minutes. Approaching the 3rd mile a friend jumped onto the treadmill next to me. I started talking to him as if we were standing still in the locker room. It actually starled me after a few seconds to realize I could TALK normally after running 3 straight miles and not be out of breath!!
Anyway, my newfound endurance feels AMAZING. Without a doubt Cordygen 5 is a new staple in my supplement arsenal. Keep up the good, no GREAT work MST!
