Hey guys, I have my MMA debut coming up on April 19th. I'd like some advice on maybe taking some No-Xplode or Nano Vapor about 30 minutes before the fight. In the past, I have taken it before training sessions and pick-up basketball games, and I could really tell a difference in my endurance. It does make me a little jittery though. I didn't know if the jitters mixed with the nerves would be too much to overcome. Any advice would be appreciated.
