Okay, here's how my body reacts:
Arginine makes me depressed and tired.
Muscle Milk makes me hyper.
Lysine makes me tense and a bit edgy.
Ephedra makes me hyper but NOT as bad as coffee (don't know the FDA banned this!)
Are there any supplements that boost endurance/energy for a workout that DON'T screw up your mental state?
