Stanozolol vs Testosterone Propionate
A side-by-side research comparison of Stanozolol and Testosterone Propionate across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Stanozolol | Testosterone Propionate |
|---|---|---|
| Full name | Stanozolol (Winstrol) | Testosterone Propionate (Short-Ester Testosterone) |
| 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. | 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 | 328.5 Da | 344.5 Da |
| Half-life | ~9 hours (oral), ~24 hours (injectable) | ~0.8-2 days |
| Bioavailability | Oral or intramuscular injection | Intramuscular/subcutaneous injection |
| Typical dose | Medical: variable for angioedema | Variable; frequent dosing required |
| Frequency | Daily (oral) | Every 1-2 days |
| Route | Oral tablet or aqueous injection | Intramuscular or subcutaneous injection |
Stanozolol reported benefits
- Lean, dry strength gains
- No water retention
- Lowers SHBG (more free hormone)
- Treats hereditary angioedema (medical)
Testosterone Propionate reported benefits
- Rapid onset of testosterone levels
- Fast clearance (flexible timing)
- Muscle mass and strength
- Less water retention than long esters (perceived)
