Testosterone enanthate is an androgen and anabolic steroid (AAS) medication which is used mainly in the treatment of low testosterone levels in men.
It is the most widely used form of testosterone in androgen replacement therapy. The medication is specifically approved, in the United States, for the treatment of hypogonadism in men, delayed puberty in boys, and breast cancer in women.
Testosterone enanthate is also used in masculinizing hormone therapy for transgender men.
