I have been using yohimbe (the bark) and yohimbine (the pharmaceutical extract) for 7 years, and it has changed my life.
Yohimbe (the bark) is what got me started on the sexual enhancement train, and I still consider yohimbine (the pharmaceutical) the strongest sexual support medication around. Nothing matches yohimbine for erection rigidity. It turns any man's flaccid organ into a forged sword.
Unfortunately, yohimbine's strength is also its primary weakness. Yohimbine is the sexual enhancement medication with the furthest reaching systemic impact: heart palpitations and excitation with insomnia for up to 30 hours can happen after ingesting even a small amount of yohimbine.
Of course, most people who try a yohimbe bark product do not have a problem with heart palpitations or sleeplessness. They also don't feel any sexual effect.
Why?
Easy answer: most yohimbe bark products (usually capsules) only contain miniscule amounts of the alkaloid yohimbine. Yohimbe bark powder that does not contain any yohimbine (or almost no yohimbine) is useless.
