The yohimbe bark herb stimulates the a2 adrenergic receptors.
It causes positive inotropic, chronotropic action, through sympatheticomimetic effect.
Twenty years ago, its use was an alternative supplementation for erectile dysfunction, due to vascular issues.
Yohimbine HCL – unlike clenbuterol and ephedrine HCL – causes peripheral vasodilation and vascular permeability.
This solves the erectile dysfunctional problems in corpus cavernosum (cavernous bodies) of the penis.
At the same time, it prevents the return of blood to the heart through the venous system.
Yohimbine was widely used, way before nitric oxide (NO) production drugs were manufactured.
In the sport of bodybuilding, Yohimbine HCL (yohimbe bark) is an ideal weapon for boosting vascularity before getting on stage.
Moreover, it enhances the process of beta oxidation and lipolysis in subcutaneous tissue.
Its action is thermogenetic and therefore increases the Basal Metabolic Rate (BMR), leading to fat catabolism.
