Mesterolone (Proviron) is an anabolic steroid used clinically to treat low testosterone, hypogonadism, oligozoospermia, and Leydig cell failure. Structurally similar to dihydrotestosterone, it has been used primarily since the early 1960s. Regulatory status varies by country; approval status in the United States is limited.
Benefits reported in the imported source
