Primobolan (Methenolone) is a high-quality anabolic steroid often regarded as one of the safest and most effective options for building lean muscle and preserving tissue during a cutting phase. It is available in two forms: Methenolone Enanthate (injectable) and Methenolone Acetate (oral).
Product Overview
Active Ingredient: Methenolone
Anabolic/Androgenic Ratio: 88:44
Aromatization: None (does not convert to estrogen).
Primary Goal: Lean muscle retention, fat loss, and enhanced muscle definition.
| Feature | Primobolan Depot (Injectable) | Primobolan (Oral) |
| Ester/Form | Enanthate (Long-acting) | Acetate (Short-acting) |
| Half-Life | ~10.5 days | ~4 – 6 hours |
| Liver Stress | Very Low | Moderate (Non-C17aa, but still processed) |
| Bioavailability | High | Lower (requires higher doses) |
Primobolan is favored for its cosmetic effects and mild nature:
Lean Muscle Retention: Excellent for holding onto muscle while on a low-calorie diet.
No Estrogenic Side Effects: Since it does not aromatize, users do not experience water retention, bloating, or gynecomastia.
Immune Support: Historically used medically to treat muscle-wasting diseases and improve immune system function.
Enhanced Vascularity: Promotes a hard, dry look, making it a staple for pre-contest preparation.
| User Level | Injectable Dosage (Weekly) | Oral Dosage (Daily) | Cycle Length |
| Beginner | 200 mg – 300 mg | 30 mg – 50 mg | 8 – 12 weeks |
| Intermediate | 400 mg – 600 mg | 50 mg – 75 mg | 10 – 12 weeks |
| Advanced | 600 mg – 800 mg+ | 75 mg – 100 mg+ | 10 – 12 weeks |
| Female | 50 mg – 100 mg | 5 mg – 10 mg | 4 – 6 weeks |
While "mild," Primobolan is still a suppressive hormone:
Androgenic Effects: Possible acne, oily skin, and increased body hair. It is known to be somewhat harsh on the hair follicles (accelerating hair loss) for those predisposed to male pattern baldness.
Testosterone Suppression: Though less suppressive than other steroids, it will still lower natural production. A proper Post Cycle Therapy (PCT) is recommended.
Cholesterol: Can cause a slight shift in HDL/LDL ratios.
