Mesterolone

Mesterolone, sold under brand names like Proviron, is a unique synthetic androgen with a distinct pharmacological profile. Unlike testosterone esters used for full androgen replacement, mesterolone is an oral DHT (dihydrotestosterone) derivative. Its clinical use is specialized, primarily centered on the management of specific symptoms of androgen deficiency, particularly in cases where the conversion of testosterone to estrogen is undesirable. It’s not a first-line treatment for classical hypogonadism requiring full-spectrum testosterone replacement but occupies a niche role.
