Nandrolone Decanoate vs Trestolone Acetate
A side-by-side research comparison of Nandrolone Decanoate and Trestolone Acetate across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Nandrolone Decanoate | Trestolone Acetate |
|---|---|---|
| Full name | Nandrolone Decanoate (Deca-Durabolin) | Trestolone Acetate (MENT) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | Prescription drug (controlled substance) | Investigational (controlled substance) |
| Mechanism | Nandrolone is testosterone lacking the 19-carbon methyl group, giving it high anabolic and lower androgenic activity. It binds androgen receptors and, unlike testosterone, converts to a weaker androgen (rather than DHT) in some tissues, reducing certain androgenic effects but not estrogen-related ones. | 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). |
| Molecular weight | 428.6 Da | 344.5 Da (acetate) |
| Half-life | ~6-12 days | ~short (acetate ester) |
| Bioavailability | Intramuscular injection | Intramuscular injection or implant |
| Typical dose | Medical: ~50-100 mg every 1-4 weeks | Very potent; low absolute doses |
| Frequency | Weekly to monthly (medical) | Daily to every other day (acetate) |
| Route | Intramuscular injection | Intramuscular injection or subdermal implant |
