Methenolone Enanthate vs Sustanon 250
A side-by-side research comparison of Methenolone Enanthate and Sustanon 250 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Methenolone Enanthate | Sustanon 250 |
|---|---|---|
| Full name | Methenolone (Primobolan) | Sustanon 250 (Testosterone Ester Blend) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | Prescription drug (controlled substance) | Prescription drug (controlled substance) |
| Mechanism | Methenolone is a DHT derivative with modest anabolic and low androgenic activity. It does not aromatize and is generally well tolerated, though the oral acetate form is not 17aa and survives via a 1-methyl group, giving lower liver stress than typical orals. | 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 | 414.6 Da (enanthate) | Blend (varies by ester) |
| Half-life | ~5-7 days (enanthate) | Mixed (~1 day to ~2 weeks across esters) |
| Bioavailability | Intramuscular injection or oral | Intramuscular injection |
| Typical dose | Lean-gain cycles (non-medical) | Medical: ~250 mg every 2-3 weeks (varies) |
| Frequency | Weekly (injectable) or daily (oral) | Every 1-3 weeks (medical) |
| Route | Intramuscular injection or oral tablet | Intramuscular injection |
