Yohimbe Bark Extract
An herbal extract used for fat loss and to support sexual health, but with significant side effects.
Also known as: Pausinystalia yohimbe
Overview
Yohimbe Bark Extract is derived from the bark of an African tree and contains the active compound yohimbine. It is often used in fat burners for its ability to block alpha-2 adrenergic receptors, which can help mobilize stubborn fat. However, it is also associated with a range of side effects.
