There is no legitimate non-medical dose and no approved product. Trestolone (MENT) is an investigational controlled substance / research chemical; this library does NOT provide a contraceptive, replacement, or body-composition dosing protocol. For context only: the human trials used SUBDERMAL MENT-ACETATE IMPLANTS (ethylene vinyl acetate implants releasing roughly 400-500 µg/day of MENT acetate per implant, one to four implants), administered under medical supervision in clinical-trial settings — not a self-administered intramuscular dose. Grey-market trestolone acetate sold for bodybuilding is illegal, unregulated, frequently mislabeled or counterfeit, and not an endorsed regimen.

Any time

No endorsed form — trestolone (MENT) is an investigational controlled substance / research chemical with no approved product; the only human-trial form is the subdermal MENT-acetate implant used in clinical studies

• Anyone seeking it for muscle, performance or anti-aging — trestolone is an unapproved controlled substance / research chemical with no marketed product; non-medical use is illegal and it is not a dietary supplement
• Men actively trying to conceive — MENT potently suppresses the HPG axis and spermatogenesis (it is a contraceptive candidate precisely because it shuts down fertility)
• Known or suspected hormone-sensitive cancer (prostate or male breast carcinoma)

• Other anabolic steroids / testosterone / SARMs
• Aromatase inhibitors / estrogen modulators
• Warfarin / oral anticoagulants
