Trestolone Acetate (Trestolone Acetate (MENT))

Category: Anabolic Steroids. Status: Investigational (controlled substance).

A highly potent synthetic 19-nortestosterone derivative (MENT, 7-alpha-methyl-19-nortestosterone) investigated as a male contraceptive and hormone replacement. Extremely androgenic and anabolic. Educational reference only.

How it works

MENT has a 7-alpha-methyl group that prevents 5-alpha-reduction, so it stays highly active in tissues without converting to DHT. It is many times more potent than testosterone, aromatizes to estrogen, and strongly suppresses gonadotropins (its contraceptive basis).

Key facts

  • Molecular weight: 344.5 Da (acetate)
  • Half-life: ~short (acetate ester)
  • Bioavailability: Intramuscular injection or implant
  • Storage: Room temperature; protect from light.

Dosing overview

  • Typical dose: Very potent; low absolute doses
  • Frequency: Daily to every other day (acetate)
  • Duration: Cycled or investigational
  • Route: Intramuscular injection or subdermal implant

Protocol notes

  • The acetate ester requires frequent injections; implant forms were studied for contraception.
  • Extremely potent, so absolute doses are low.
  • Strong gonadotropin suppression underlies its contraceptive research use.

Reported benefits

  • Very high anabolic/androgenic potency
  • No DHT conversion
  • Supports libido strongly
  • Studied for male contraception/HRT

Possible side effects

  • Strong estrogen conversion (gyno)
  • Strong testosterone/fertility suppression
  • Adverse lipids
  • Androgenic effects
  • Frequent injections (acetate)

Research

  • MENT as male contraceptive/androgen (2016): Suppressed spermatogenesis while maintaining androgenic effects, supporting contraceptive and HRT investigation.
