Trestolone Acetate (Trestolone Acetate (MENT))
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.
