Prolactin elevation is a specific risk of 19-Nortestosterone derivatives (nandrolone, trenbolone) due to their agonism at dopamine D2 receptors in the pituitary and direct stimulation of lactotrophic cells. Elevated prolactin (above 25 ng/mL) suppresses GnRH secretion, further impairing HPTA recovery, and can cause sexual dysfunction, gynecomastia, and galactorrhea.
