In the world of bodybuilding and sports performance enhancement, athletes often seek reliable ways to enhance their physical capabilities. Oxanobol, also known as Oxandrolone, is a popular oral drug manufactured by SP-Laboratories that has gained significant attention in recent years. This article will provide you with a comprehensive overview of Oxanobol, covering its general description, indications, contraindications, uses in bodybuilding and sport, medical actions, combination with other drugs, dosage recommendations, and potential side effects.

General Description:

Oxanobol, produced by SP-Laboratories, is a synthetic anabolic steroid. It belongs to a class of drugs known as androgens, which are responsible for the development and maintenance of male characteristics in the body. Oxandrolone, the active ingredient in Oxanobol, is derived from dihydrotestosterone (DHT), making it one of the mildest and safest anabolic steroids available.


Oxanobol is primarily prescribed for medical purposes, including:

  1. Muscle Wasting Disorders: Oxandrolone is used to treat conditions such as HIV/AIDS-related muscle wasting and other diseases that cause muscle loss. It helps patients regain lean muscle mass and improve overall body composition.
  2. Burn Injuries: It is also prescribed to patients recovering from severe burns as it aids in the preservation of lean tissue and promotes wound healing.
  3. Turner Syndrome: Oxandrolone may be used in the treatment of Turner syndrome, a genetic disorder in females that affects growth.


Despite its therapeutic benefits, Oxanobol should not be used in certain situations, including:

  1. Hypersensitivity: Individuals with a known allergy to Oxandrolone or any of its components should avoid using this medication.
  2. Prostate Cancer: It is contraindicated in individuals with prostate cancer.
  3. Breast Cancer: Oxanobol should not be used by individuals with breast cancer.
  4. Pregnancy: It is not recommended for use during pregnancy due to potential harm to the developing fetus.

Uses in Bodybuilding and Sport:

Oxanobol has gained popularity among athletes and bodybuilders for its potential to enhance performance and physique. Its use in this context is often associated with the following benefits:

  1. Lean Muscle Gain: Oxandrolone promotes lean muscle growth without causing excessive water retention, making it suitable for those looking to gain quality muscle mass.
  2. Strength Enhancement: Users report increased strength and endurance, which can improve performance in both training and competition.
  3. Fat Loss: Oxanobol can aid in fat loss by increasing metabolism and promoting a more defined, vascular appearance.
  4. Muscle Preservation: It is commonly used during cutting phases to preserve muscle mass while reducing body fat.

Medical Action:

Oxandrolone’s mechanism of action involves binding to androgen receptors in the body. This binding stimulates protein synthesis, leading to muscle tissue growth and repair. Additionally, it can increase red blood cell production, enhancing oxygen transport to muscles, which can improve endurance and overall performance.

Combining with Other Drugs:

In bodybuilding and sports, Oxanobol is often stacked with other compounds to maximize results. Some common combinations include:

  1. Testosterone: Combining Oxanobol with testosterone can enhance muscle gains and overall performance.
  2. Winstrol: Oxandrolone and Winstrol are frequently used together during cutting cycles for a leaner, more defined physique.
  3. Clenbuterol: For fat loss and improved conditioning, athletes may combine Oxanobol with Clenbuterol.


The dosage of Oxanobol can vary depending on individual goals and experience. For men, a typical starting dose is 20-50mg per day, while women often start with 5-10mg per day. It’s crucial to consult a healthcare professional or experienced coach before starting any Oxandrolone regimen to determine the appropriate dosage for your specific needs.

Side Effects:

While Oxanobol is considered a relatively safe anabolic steroid, it is not without potential side effects. Common side effects may include:

  1. Liver Strain: Prolonged use or high doses can put strain on the liver. Regular monitoring of liver function is essential during Oxanobol use.
  2. Virilization: In women, Oxandrolone may cause virilization symptoms such as deepening of the voice, facial hair growth, and clitoral enlargement.
  3. Cardiovascular Effects: It can affect cholesterol levels, potentially leading to increased LDL cholesterol and decreased HDL cholesterol.
  4. Suppression of Natural Testosterone: Prolonged use can suppress the body’s natural testosterone production, leading to potential hormonal imbalances.


Oxanobol, manufactured by SP-Laboratories, is a versatile compound with both medical and performance-enhancing applications. It is essential to use this drug responsibly, under the guidance of a healthcare professional, and to be aware of its potential side effects. Whether used for medical reasons or to enhance athletic performance, Oxanobol remains a subject of interest and ongoing research in the world of sports and bodybuilding. Always prioritize safety and consult with a knowledgeable healthcare provider before considering its use.
