Methyltestosterone vs Testosterone Propionate
A side-by-side research comparison of Methyltestosterone and Testosterone Propionate across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Methyltestosterone | Testosterone Propionate |
|---|---|---|
| Full name | Methyltestosterone (Oral Testosterone) | Testosterone Propionate (Short-Ester Testosterone) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | FDA-approved drug (controlled substance) | Prescription drug (controlled substance) |
| Mechanism | A 17-alpha-alkylated testosterone that survives first-pass liver metabolism, allowing oral dosing. It acts on androgen receptors like testosterone and aromatizes to estrogen, but its 17aa structure makes it hepatotoxic. | Testosterone bound to a small propionate ester, giving rapid release and a short half-life. It acts on androgen receptors identically to other testosterone forms but with faster onset and offset of blood levels. |
| Molecular weight | 302.5 Da | 344.5 Da |
| Half-life | ~2.5-4 hours | ~0.8-2 days |
| Bioavailability | Oral (17aa) | Intramuscular/subcutaneous injection |
| Typical dose | Medical: ~10-50 mg/day (historical) | Variable; frequent dosing required |
| Frequency | Daily | Every 1-2 days |
| Route | Oral or buccal tablet | Intramuscular or subcutaneous injection |
Methyltestosterone reported benefits
