Stanozolol vs Sustanon 250
A side-by-side research comparison of Stanozolol and Sustanon 250 across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Stanozolol | Sustanon 250 |
|---|---|---|
| Full name | Stanozolol (Winstrol) | Sustanon 250 (Testosterone Ester Blend) |
| Category | Anabolic Steroids | Anabolic Steroids |
| Status | FDA-approved drug (controlled substance) | Prescription drug (controlled substance) |
| Mechanism | Stanozolol is a 17-alpha-alkylated DHT derivative that is orally active and resists aromatization. It has a relatively high anabolic-to-androgenic ratio and lowers sex-hormone-binding globulin (SHBG), increasing free hormone levels. | 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 | 328.5 Da | Blend (varies by ester) |
| Half-life | ~9 hours (oral), ~24 hours (injectable) | Mixed (~1 day to ~2 weeks across esters) |
| Bioavailability | Oral or intramuscular injection | Intramuscular injection |
| Typical dose | Medical: variable for angioedema | Medical: ~250 mg every 2-3 weeks (varies) |
| Frequency | Daily (oral) | Every 1-3 weeks (medical) |
| Route | Oral tablet or aqueous injection | Intramuscular injection |
