Methyltestosterone vs Sustanon 250
A side-by-side research comparison of Methyltestosterone and Sustanon 250 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Methyltestosterone | Sustanon 250 |
|---|---|---|
| Full name | Methyltestosterone (Oral Testosterone) | Sustanon 250 (Testosterone Ester Blend) |
| 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. | Combines short, medium, and long esters so testosterone is released at staggered rates, producing a rapid initial rise followed by sustained levels. The active hormone is standard testosterone acting on androgen receptors. |
| Molecular weight | 302.5 Da | Blend (varies by ester) |
| Half-life | ~2.5-4 hours | Mixed (~1 day to ~2 weeks across esters) |
| Bioavailability | Oral (17aa) | Intramuscular injection |
| Typical dose | Medical: ~10-50 mg/day (historical) | Medical: ~250 mg every 2-3 weeks (varies) |
| Frequency | Daily | Every 1-3 weeks (medical) |
| Route | Oral or buccal tablet | Intramuscular injection |
