Yohimbine is a substance found in the Pausinystalia yohimbe plant, and helps block a mechanism in fat cells that prevents weight loss, which in turn speeds up fat loss.
There’s a catch, though: you must be in a fasted state for it to work. The insulin spike that occurs after eating a meal completely negates the beneficial effects of yohimbine.
NOTE: As with anything, excess doses can have negative side effects. Don’t go crazy with this. Furthermore, yohimbine has been shown to raise blood pressure. If you have high blood pressure, I don’t recommend you use it.
When taking yohimbine, I recommend following the protocol laid out in this article.
