SCI-FIT?s® Massive Yohimbe 1200™ is one of the most potent Yohimbe Bark Extracts available. The active ingredient in Yohimbe Bark extract is Yohimbine. Yohimbine has been used as an aphrodisiac for centuries. Yohimbine can cause a significant increase in the release of noradrenalin from nerve endings. This action stimulates the nervous system, raises core temperature, and causes the body to mobilize body fat for fuel. Yohimbine serves as a potent stimulant, aphrodisiac, and as a significant aid in a weight loss program. The majority of the "Yohimbe" products on the market contain 10mg or substantially less of the active ingredient Yohimbine. SCI-FIT?s® Massive Yohimbe 1200™ contains an astounding 24mg of Yohimbine per serving!
