Microdosing to unlock capabilities

I recreationally participate in endurance sports such as running and biking. As many coaches will tell you; your biggest limitation is your own mind, as the body can endure more than you think.
Dosing a single capsule near the beginning of a race allows an opening of my mind during the race about when I start fatiguing and start to question my commitment to finishing. This allows me to look beyond the physical discomfort and enjoy the pleasure of the participation in the event whether that is biking on the mountain or running a course.
It does not cause me to go beyond my personal fitness limitations but it does allow me to stretch those limits thereby increasing my fitness level along the way. I encourage adult athletes to try this method of stretching their limits normally introduced by their minds.
