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.
Community reviews of Trestolone Acetate
- cold_chain_carl rated it 4/5 - Noticed clear benefits within weeks: Added Trestolone Acetate to my protocol about 2 months ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
- fasted_frank rated it 5/5 - Solid compound with real results: Been using Trestolone Acetate for about 2 weeks and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
- subq_samantha rated it 4/5 - Worth adding to the protocol: Trestolone Acetate has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
