In the world of bodybuilding and sports performance enhancement, athletes and fitness enthusiasts are always on the lookout for safe and effective ways to reach their goals. One such oral drug that has gained popularity in recent years is Primobol (Tabs), also known as Methenolone Acetate. Manufactured by SP-Laboratories, Primobol (Tabs) is a versatile compound with various applications in both medical and sports-related contexts. In this comprehensive guide, we will delve into its general description, indications, contraindications, uses in bodybuilding and sports, medical actions, combinations with other drugs, recommended dosages, and potential side effects.

General Description:

Primobol (Tabs), or Methenolone Acetate, is a synthetic anabolic steroid derived from dihydrotestosterone (DHT). Unlike some other steroids, it is available in an oral tablet form, making it more accessible to users who prefer avoiding injections. Its chemical structure is altered to increase its anabolic properties while reducing its androgenic effects, making it a mild and well-tolerated option for both men and women.


Primobol (Tabs) has been primarily indicated for medical purposes in the treatment of muscle-wasting conditions, such as malnutrition, chronic illness, and post-surgery recovery. Its ability to promote lean muscle mass growth while minimizing water retention and unwanted fat gain makes it a valuable tool in combating muscle loss.


While Primobol (Tabs) is generally well-tolerated, it is not without contraindications. Individuals with a history of hypersensitivity or allergy to Methenolone Acetate should avoid its use. Moreover, pregnant and breastfeeding women should refrain from using this compound due to the potential risks to the fetus or nursing infant.

Uses in Bodybuilding and Sport:

Primobol (Tabs) has found a significant place in the world of bodybuilding and sports due to its unique properties. Athletes and bodybuilders use it for:

  1. Lean Muscle Gain: Primobol (Tabs) promotes the development of lean muscle mass, providing users with a sculpted, defined physique.
  2. Enhanced Performance: It boosts strength and endurance, enabling athletes to push their limits during training and competitions.
  3. Preservation of Muscle Mass: During cutting phases, where athletes aim to reduce body fat while retaining muscle, Primobol (Tabs) is invaluable.
  4. Improved Recovery: It aids in faster post-workout recovery, allowing athletes to train more frequently and intensively.

Medical Action:

Primobol (Tabs) exerts its medical actions through anabolic and androgenic effects. Its anabolic properties stimulate protein synthesis, which is essential for muscle growth and repair. Additionally, it helps in increasing red blood cell production, improving oxygen delivery to muscles, and reducing cortisol levels, which can lead to muscle breakdown.

Combining with Other Drugs:

In the realm of bodybuilding, Primobol (Tabs) is often used in combination with other drugs to enhance its effects and mitigate potential side effects. Some common stacks include:

  1. Primobol (Tabs) and Testosterone: Combining with a testosterone base can maximize muscle growth potential while minimizing the risk of sexual side effects.
  2. Primobol (Tabs) and Anavar: This stack is favored during cutting cycles for lean muscle preservation and fat loss.
  3. Primobol (Tabs) and Trenbolone: Advanced users may choose this stack for substantial gains in muscle mass and strength.


Dosage recommendations for Primobol (Tabs) can vary depending on individual goals and experience levels. For men, a typical dosage ranges from 50mg to 150mg per day. Women, on the other hand, should stick to lower doses, typically between 10mg to 50mg per day to avoid virilization effects.

It’s crucial to start with the lowest effective dose and monitor for any adverse reactions. Always consult with a healthcare professional or experienced coach before starting any steroid regimen.

Side Effects:

While Primobol (Tabs) is considered mild in comparison to many other steroids, it is not entirely free of potential side effects. Common side effects may include:

  1. Androgenic Effects: These can include acne, increased body hair growth, and in women, virilization symptoms like deepening of the voice and clitoral enlargement.
  2. Cardiovascular Risks: Steroids, in general, can affect cholesterol levels, potentially leading to an increased risk of cardiovascular issues.
  3. Liver Toxicity: Although less hepatotoxic than some other oral steroids, Primobol (Tabs) may still place stress on the liver if used at high doses or for extended periods.

Suppression of Natural Hormone Production: Prolonged use can suppress the body’s natural testosterone production, necessitating post-cycle therapy (PCT) to restore hormonal balance.


Primobol (Tabs), or Methenolone Acetate, is a versatile oral steroid manufactured by SP-Laboratories. It offers a range of benefits, making it a popular choice for bodybuilders and athletes. However, like any performance-enhancing drug, it should be used responsibly, with careful attention to dosages, potential side effects, and in consultation with a healthcare professional or coach. Always prioritize safety and health when considering the use of Primobol (Tabs) or any other anabolic steroid.
