Cabergoline is a dopamine agonist designed to reduce prolactin. In medical circles it is commonly used to combat prolactinomas, a benign tumor of the pituitary gland that may cause an excess production of prolactin. It is also used by athletes who supplement with anabolic steroids that may increase prolactin levels such as Nandrolone and Trenbolone.

As a therapeutic agent, Proviron is one of the most commonly used anabolic steroids in modern medicine.
