Prolactin

Category: Hormones
Unit: mIU/L

Hormone from pituitary gland. Elevated levels can affect sexual function and mood.

PED Notes

19-nor compounds (Nandrolone, Trenbolone) can significantly elevate prolactin. High prolactin causes sexual dysfunction (erectile issues, anorgasmia), gyno risk, and in extreme cases lactation. Should be monitored on any 19-nor cycle. If prolactin is elevated without 19-nor use, investigate pituitary function.

First-line (mild elevation):

  • P5P (active Vitamin B6) -- 50-100mg/day, often sufficient
  • Vitamin E -- 400 IU/day

Second-line (significant elevation):

  • Cabergoline (Dostinex) -- 0.25-0.5mg 2x/week, potent dopamine agonist
