Methenolone Enanthate (Methenolone (Primobolan))
A mild DHT-derived anabolic steroid (Primobolan) available as an injectable enanthate or oral acetate, valued for lean, low-side-effect gains and a reputation as one of the "safer" anabolics. Educational reference only.
How it works
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.
Key facts
- Molecular weight: 414.6 Da (enanthate)
- Half-life: ~5-7 days (enanthate)
- Bioavailability: Intramuscular injection or oral
- Storage: Room temperature; protect from light.
Dosing overview
- Typical dose: Lean-gain cycles (non-medical)
- Frequency: Weekly (injectable) or daily (oral)
- Duration: Cycled
- Route: Intramuscular injection or oral tablet
Protocol notes
- Injectable enanthate is dosed roughly weekly; oral acetate is dosed daily.
- Considered mild, favored for lean gains with fewer side effects.
- Often combined with testosterone in non-medical use.
Reported benefits
- Lean, quality gains
- Low side-effect profile (relative)
- No aromatization
- Preserves lean mass in a deficit
- Mild on liver (oral acetate)
Possible side effects
- Testosterone suppression
- Adverse lipids
- Androgenic effects (hair loss)
- Cost (often expensive/counterfeited)
Research
- Methenolone tolerability profile (2014): Showed anabolic activity with comparatively low androgenic and hepatic burden in historical clinical use.
