What is Cabergoline?

Cabergoline is a dopamine agonist originally developed to treat conditions caused by high prolactin levels, such as certain pituitary tumours and hormone imbalances. It works directly on the brain to lower prolactin production. In performance circles it's widely used to keep prolactin-related side effects in check during certain steroid cycles.

Quick Facts

How Does It Work?

Cabergoline binds to dopamine D2 receptors in the pituitary gland. This signals the gland to produce less prolactin. Lower prolactin levels help prevent side effects like gynecomastia and sexual dysfunction that can occur with certain progestin-based steroids.

What It's Used For

• Controlling elevated prolactin levels during steroid cycles
• Medical treatment of hyperprolactinaemia and prolactin-secreting tumours
• Managing progesterone-related side effects from compounds like Deca or Trenbolone

What to Expect

Prolactin levels typically drop noticeably within the first week of use. Many users report improved libido and sexual function once prolactin is brought under control. At low doses it is generally well tolerated with minimal disruption to daily life.

Possible Side Effects

• Nausea or upset stomach, especially when first starting
• Dizziness or light-headedness, particularly when standing up quickly
• Fatigue or mild mood changes at higher doses

Cycle & Dosage Notes

Cabergoline is typically run throughout the duration of a cycle that includes prolactin-raising compounds, at 0.25–0.5 mg twice per week. It is not a hormonal compound itself, so it does not require PCT. Starting at the lower end of the dose range is recommended to assess individual tolerance.

Storage

Keep at room temperature (15–25°C), away from light and moisture. Leave in the original packaging.
