In the realm of bodybuilding and sports performance enhancement, the quest for effective anabolic steroids continues. Nandrolone Phenylpropionate, commonly known as Fenandrol 10, is one such injectable drug that has captured the attention of athletes and bodybuilders alike. Manufactured by Balkan Pharmaceuticals, Fenandrol 10 holds a unique position in the world of performance-enhancing substances. This article will provide an in-depth exploration of Fenandrol 10, covering its general description, indications, contraindications, uses in bodybuilding and sport, medical action, combination with other drugs, recommended dosage, and potential side effects.

General Description:

Fenandrol 10, or Nandrolone Phenylpropionate, is a synthetic anabolic steroid derived from testosterone. Balkan Pharmaceuticals, a reputable pharmaceutical company, produces this injectable drug. It is often found in the form of a clear, yellowish oil-based solution intended for intramuscular administration. As a short-acting ester, Fenandrol 10 has a relatively rapid onset of action compared to its longer-acting counterpart, Nandrolone Decanoate.


Nandrolone Phenylpropionate, like other anabolic steroids, was originally developed to treat certain medical conditions. It was primarily indicated for the treatment of:

  1. Anemia: Fenandrol 10 can stimulate the production of red blood cells, which helps combat anemia, a condition characterized by a reduced number of red blood cells and hemoglobin.
  2. Muscle Wasting: It has been used to counteract muscle wasting associated with chronic illnesses, such as HIV/AIDS, cancer, and kidney disease.


While Fenandrol 10 may have therapeutic benefits, it is not without its contraindications. It should not be used by individuals who:

  1. Have a history of hypersensitivity or allergic reactions to the drug.
  2. Are pregnant or planning to become pregnant, as it may have virilizing effects on a developing fetus.
  3. Have prostate cancer or breast cancer.
  4. Have a history of liver or kidney disease.
  5. Are under 18 years of age, as the effects of anabolic steroids on developing bodies are not well understood.

Uses in Bodybuilding and Sport:

Fenandrol 10 has gained popularity among bodybuilders and athletes for its anabolic properties. Some of its notable uses in the world of sports and bodybuilding include:

  1. Lean Muscle Gain: Fenandrol 10 promotes nitrogen retention and protein synthesis in the muscles, leading to increased lean muscle mass.
  2. Enhanced Recovery: Athletes often use it to accelerate recovery from strenuous workouts or injuries.
  3. Improved Endurance: Some athletes believe that Fenandrol 10 can boost their endurance and stamina, enabling them to train harder and longer.
  4. Joint Health: It is also known for its potential to alleviate joint pain and discomfort, which can be beneficial for athletes engaged in high-impact sports.

Medical Action:

Fenandrol 10 exerts its effects through the following mechanisms:

  1. Protein Synthesis: It enhances the rate of protein synthesis in muscle cells, leading to muscle growth and repair.
  2. Nitrogen Retention: The drug increases the retention of nitrogen in the muscles, promoting an anabolic environment that is conducive to muscle growth.
  3. Increased Red Blood Cell Production: Fenandrol 10 can stimulate the production of red blood cells, which improves oxygen delivery to the muscles and enhances endurance.

Combination with Other Drugs:

In bodybuilding and sports circles, Fenandrol 10 is often stacked with other compounds to maximize its effects. Common combinations include:

  1. Testosterone: Combining Fenandrol 10 with testosterone is a popular choice to enhance overall muscle gains and reduce the risk of sexual side effects associated with the use of Fenandrol 10 alone.
  2. Anabolic Steroids: Some athletes stack Fenandrol 10 with other anabolic steroids to achieve specific physique goals, although this practice should be approached with caution due to potential side effects.


The recommended dosage of Fenandrol 10 can vary depending on individual goals, experience level, and tolerance. However, a typical dosage for male bodybuilders and athletes ranges from 100mg to 200mg per week, divided into two or three injections. Female users are advised to use lower doses, usually around 50mg per week to avoid virilizing effects.

It is essential to consult a healthcare professional or experienced bodybuilder before starting any steroid cycle to determine the most suitable dosage and cycle duration.

Side Effects:

While Fenandrol 10 can offer significant benefits, it is not without potential side effects. Common side effects may include:

  1. Virilization: Women who use Fenandrol 10 are at risk of developing male characteristics such as facial hair growth, deepening of the voice, and clitoral enlargement.
  2. Cardiovascular Issues: Anabolic steroids, including Fenandrol 10, can adversely affect cholesterol levels and increase the risk of cardiovascular problems.
  3. Hormonal Imbalance: The use of anabolic steroids can disrupt the body’s natural hormonal balance, leading to issues like reduced testosterone production.
  4. Liver Toxicity: While Fenandrol 10 is considered less liver toxic than some other steroids, it can still impact liver function.


Fenandrol 10, also known as Nandrolone Phenylpropionate, manufactured by Balkan Pharmaceuticals, is a potent anabolic steroid with both therapeutic and performance-enhancing applications. It offers benefits such as increased muscle mass, improved recovery, and enhanced endurance. However, it should be used cautiously, under the guidance of a healthcare professional or experienced bodybuilder, to mitigate potential side effects and ensure safe and responsible use in both medical and sports settings. Always prioritize your health and well-being when considering the use of any performance-enhancing substance.
