Used primarily in research and clinical settings to investigate and treat conditions related to sexual dysfunction, particularly erectile dysfunction. It acts as an alpha-2 adrenergic receptor antagonist, which helps increase norepinephrine release and improve blood flow, contributing to its stimulatory effects on sexual function. Also studied for its potential to support weight loss by enhancing lipolysis in fat tissue, though results are inconsistent. Occasionally used off-label for orthostatic hypotension due to its ability to influence vascular tone. Found in some dietary supplements aimed at improving athletic performance and energy, although efficacy and safety in these contexts remain questionable. Its stimulant and psychoactive properties require careful handling and medical supervision.
