Androcap 40 mg contains Testosterone Undecanoate, a synthetic form of the male hormone testosterone. It is used for the treatment of male hypogonadism, a condition where the body does not produce enough testosterone. Testosterone plays a crucial role in the development of male sexual characteristics, muscle mass, and bone density. Androcap is typically used to restore testosterone levels and alleviate symptoms such as fatigue, low libido, and erectile dysfunction.
