Effects

  • Raises total & free testosterone: 12.5-25 mg/day restored testosterone to a normal 400-700 ng/dL range in hypogonadal men, comparable to topical testosterone, often within ~2 weeks [2][6][8].
  • Increases LH and FSH: Drives the body's own gonadotropin output rather than replacing hormones [2][3][6].
  • Preserves fertility: Maintains sperm production, unlike TRT which commonly lowers sperm count [1][6].
  • Does not raise DHT disproportionately: Unlike topical testosterone, it produced only a modest change in DHT relative to total testosterone [6].
  • Carryover effect: Testosterone, LH and FSH stay elevated for about a week after stopping, so a missed dose is unlikely to cause an immediate drop [4][9].
