Long-acting — weekly dosing keeps levels steady. After the last dose, roughly 97% has cleared in ~5 weeks (five half-lives) — the window that matters for washouts, bloodwork and surgery.
What Trestolone (MENT) is used for
- Highly potent anabolic that supports significant muscle and strength gains
- Does not convert to DHT, so scalp and prostate DHT effects are limited
- Long-acting ester allows infrequent injections
How it's typically used
Anecdotal user reports describe roughly 10 mg daily equivalents, framed as reported practice and not a recommendation.
What to watch for
- Strongly suppresses natural testosterone, requiring a recovery protocol
- Aromatizes to a potent estrogen, so estrogen management is often needed
- Can strain lipids and cardiovascular health
- An unapproved anabolic steroid and controlled substance; illegal without a prescription in most countries
About Androgens & steroids
- What they are
- Anabolic-androgenic steroids — testosterone and its derivatives. These are drugs, not peptides, and are controlled substances in most countries.
- How they're run
- Injected intramuscularly or subcutaneously on a schedule set by the ester's half-life; a few are oral and hepatotoxic.
- What to watch
- Every one of these shuts down your own testosterone production. Full bloodwork before, during, and after is not optional, and an exit plan — PCT or ongoing replacement — is part of the decision to start, not an afterthought.
