Back in college, one of my roommates gave me a couple of Xenadrine before football practice. I had taken supplements like Ultimate Orange and Ripped Fuel in the past, both of which are supposed to increase your metabolism and get you “pumped up”, but this was the first time I had taken ma huang (aka ephedra).
4 hours later, my heart felt like it was going to pound right through my chest.
Scary stuff. What's worse is that it's not even regulated!
This decision was a long time coming.
