Methyltestosterone vs Testosterone Enanthate
A side-by-side research comparison of Methyltestosterone and Testosterone Enanthate across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Methyltestosterone | Testosterone Enanthate |
|---|---|---|
| Full name | Methyltestosterone (Oral Testosterone) | Testosterone Enanthate (Long-Ester Testosterone) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | FDA-approved drug (controlled substance) | FDA-approved 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. | A testosterone molecule attached to an enanthate ester that slows release from the injection site. Once cleaved, testosterone binds androgen receptors to increase muscle protein synthesis, nitrogen retention, red blood cell production, and secondary sexual characteristics. |
| Molecular weight | 302.5 Da | 400.6 Da |
| Half-life | ~2.5-4 hours | ~4.5-5 days |
| Bioavailability | Oral (17aa) | Intramuscular/subcutaneous injection |
| Typical dose | Medical: ~10-50 mg/day (historical) | TRT ~100-200 mg/week (medical) |
| Frequency | Daily | 1-2x weekly |
| Route | Oral or buccal tablet | Intramuscular or subcutaneous injection |
