Cabergoline is a dopamine agonist primarily used in medicine to treat hyperprolactinemia (high prolactin levels) and disorders like prolactinomas. In bodybuilding, it is not used for muscle growth directly, but rather as a supportive compound during or after anabolic steroid cycles—especially those involving 19-nor compounds like nandrolone (Deca) or trenbolone.

These compounds can increase prolactin levels, leading to side effects such as:

• Gynecomastia (especially “gyno” not related to estrogen)

• Low libido

• Erectile dysfunction

• Mood disturbances

Cabergoline helps by reducing prolactin, thereby alleviating or preventing these issues. It also has anecdotal benefits reported in terms of:

• Improved sexual function and libido

• Enhanced well-being and mood

• Possible increase in dopamine-related motivation

Typical dosage ranges from 0.25 mg to 0.5 mg twice per week, depending on individual response and bloodwork. It should be used cautiously and under medical supervision, as misuse can lead to side effects like low blood pressure, dizziness, or heart valve issues with long-term abuse.
