Cabergoline and Muscle Fiber Growth: Can It Improve Hypertrophy?
-
Cabergoline for Bodybuilding a dopamine agonist primarily used to treat hyperprolactinemia and Parkinson’s disease, has been speculated to influence muscle growth due to its effects on prolactin and growth hormone (GH) regulation. Prolactin suppression by cabergoline may indirectly enhance GH secretion, which plays a role in muscle hypertrophy. However, there is limited direct evidence linking cabergoline to significant muscle fiber growth or hypertrophy in humans.
While GH and IGF-1 are critical for muscle repair and growth, cabergoline’s impact on these pathways is not well-documented in the context of muscle hypertrophy. Some anecdotal reports suggest potential benefits in body composition, but these are not supported by robust clinical studies. Additionally, cabergoline’s side effects, such as dizziness, nausea, and potential heart valve issues, make it unsuitable for off-label use in muscle building.
