Cabergoline was originally designed as a treatment of medical problems related to the hormone prolactin. Used to treat menstrual irregularities and fertility problems, cabergoline is also commonly used by bodybuilders in combination with other supplements and products for increased muscle mass without adding excess body fat. However, cabergoline is a treatment for medical problems, and can only be prescribed by a doctor for medical reasons.


Cabergoline is the active ingredient in Dostinex – a medical product used to inhibit the production of prolactin from the pituitary gland. Originally used to fight the effects of aging, bodybuilders also found benefits of using cabergoline. Bodybuilders use cabergoline to control gynecomastia that prevents the negative effects of prolactin on muscle development through the use of anabolic steroids.


While cabergoline is only available with a doctor’s prescription, bodybuilders incorporate cabergoline into their normal supplement cycles. For example, bodybuilders may “cycle” off and on specific supplements and anabolic steroids such as Tren and Deca. Cabergoline is used by the bodybuilders at the same time during these cycles; other ingredients commonly added with cabergoline include anhydrous lactose and leucine.


Cabergoline can be taken orally in pill or liquid form. One cabergoline tablet typically contains 0.5 mg of cabergoline as the primary active ingredient. The recommended dosage is 0.25 mg two times per week, with a maximum dosage of 1 mg. If bodybuilders exceed these dosage recommendations, they can also experience nasal congestion and hallucinations.


By inhibiting the production of prolactin, cabergoline has numerous effects on a bodybuilder’s physique. A common goal for bodybuilders is to increase testosterone levels that ultimately lead to an increase in muscle growth and size. By reducing the total amount of prolactin, the body is able to increase testosterone levels. Cabergoline can also be used in combination with anabolic steroids and nutritional supplements without affecting their benefits.


Similar to any prescription medication, cabergoline can cause numerous negative side effects. Always consult a doctor before using cabergoline or any additional supplements. Using cabergoline without discussing it with a doctor can cause adverse reactions with medications, supplements or existing health issues. Common side effects linked to cabergoline include nausea, vomiting, constipation, dizziness and fatigue.
