Primoabolan BS
Primoabolan BS: Anabolic-androgenic steroid for muscle growth and strength enhancement. Active ingredient is methenolone enanthate. 10ml vial, 200mg/ml concentration.
What is Primoabolan BS?
Primoabolan BS, a.k.a. Methenolone Enanthate, is an injectable anabolic androgenic steroid (AAS) known for its high anabolic activity and low androgenic properties. It’s widely used in the bodybuilding community for its ability to promote muscle growth, enhance strength, and improve recovery.
History and Background
The history of Primoabolan BS dates back to the 1960s when it was developed by Squibb. However, it’s important to note that the product discussed here is a generic version manufactured under strict quality control measures.
How Does Primoabolan BS Work?
Primoabolan BS works by increasing nitrogen retention in muscle tissue. Nitrogen is essential for protein synthesis, which is crucial for muscle growth and repair. By enhancing nitrogen retention, this steroid promotes anabolic activity, helping users build lean muscle mass.
Key Features of Primoabolan BS
- High Anabolic Rating: With an anabolic rating of 88 (testosterone’s being 100), it promotes significant muscle growth with minimal side effects.
- Low Androgenic Rating: Having an androgenic rating of just 44, Primoabolan BS minimizes the risk of androgen-related side effects such as hair loss and acne.
- Long Esters: The Enanthate ester attached to Methenolone slows down its release into the body, allowing for less frequent injections (once or twice a week).
Benefits of Primoabolan BS
Primoabolan BS offers numerous benefits to sports enthusiasts and bodybuilders. Here are some key advantages:
- Muscle Growth: Primoabolan BS promotes lean muscle mass, helping users achieve a more muscular physique.
- Strength Enhancement: By increasing nitrogen retention, it also enhances strength levels, enabling users to handle heavier weights and perform more intense workouts.
- Improved Recovery: It speeds up recovery time by promoting muscle tissue repair and regeneration.
- Increased Endurance: Some users report improved endurance and cardiovascular efficiency, allowing for longer, more intense workout sessions.

Side Effects of Primoabolan BS
While generally well-tolerated, Primoabolan BS can cause side effects in some individuals. Here are the most common ones:
- Androgenic Side Effects: Although rare due to its low androgenic rating, hair loss (MPB) and acne are possible.
