Stanozolol, also commonly known as Stanozol, is a powerful oral drug that has gained popularity both in the medical field and among athletes and bodybuilders. Manufactured by SP-Laboratories, this compound offers a myriad of potential benefits, but it’s essential to understand its general description, indications, contraindications, uses in bodybuilding and sports, medical action, combinations with other drugs, dosage, and potential side effects. In this article, we will delve into the details of Stanozolol to provide you with a comprehensive understanding of this compound.

General Description:

Stanozolol, often referred to by its brand name Stanozol, belongs to a class of drugs known as anabolic steroids. Anabolic steroids are synthetic derivatives of the male sex hormone testosterone. Stanozolol is specifically a synthetic anabolic steroid derived from dihydrotestosterone (DHT).

This compound is available in both oral and injectable forms, but we will focus on the oral variant. Stanozolol is well-known for its ability to promote muscle growth, increase strength, and enhance athletic performance. It is widely used in the world of bodybuilding and sports due to these desirable effects.


Stanozolol has been used medically to treat a variety of conditions. Its primary medical indications include:

  1. Angioedema: Stanozolol can be prescribed to individuals suffering from hereditary angioedema, a condition characterized by episodes of severe swelling beneath the skin.
  2. Anemia: It may be used to treat anemia by stimulating the production of red blood cells.
  3. Burn Victims: Stanozolol is sometimes prescribed to burn victims to help them recover muscle and tissue mass lost during injuries.


Despite its therapeutic uses, Stanozolol is not suitable for everyone. It is contraindicated in the following cases:

  1. Pregnancy: Stanozolol should not be used during pregnancy as it may cause harm to the developing fetus.
  2. Breastfeeding: Women who are breastfeeding should also avoid Stanozolol, as it can pass into breast milk and affect the nursing infant.
  3. Prostate Cancer: Individuals with prostate cancer or a history of prostate cancer should not use this drug, as it may worsen the condition.

Uses in Bodybuilding and Sport:

Stanozolol is highly favored by bodybuilders and athletes due to its ability to provide several performance-enhancing benefits, including:

  1. Increased Muscle Mass: Stanozolol promotes lean muscle growth, making it a valuable addition to bulking cycles.
  2. Enhanced Strength: Users often experience significant increases in strength, which can aid in more intense workouts.
  3. Improved Endurance: Stanozolol can boost endurance, allowing athletes to perform better for longer periods.
  4. Cutting and Definition: It is also popular during cutting cycles, as it helps preserve lean muscle mass while promoting fat loss.

Medical Action:

Stanozolol exerts its effects by binding to androgen receptors in the body, which stimulates protein synthesis and nitrogen retention. This leads to an increase in muscle mass and enhanced recovery between workouts. Additionally, it can increase the production of red blood cells, which helps improve oxygen delivery to muscles, further enhancing performance.

Combining with Other Drugs:

Stanozolol can be used in combination with other drugs to achieve specific goals. However, it’s crucial to consult with a healthcare professional or a knowledgeable coach before combining it with other substances. Some common combinations include:

  1. Testosterone: Combining Stanozolol with testosterone can enhance muscle growth and overall performance.
  2. Anavar: Stacking Stanozolol with Anavar can lead to impressive gains in muscle definition and vascularity.
  3. Trenbolone: Stanozolol can be combined with Trenbolone to increase muscle hardness and overall physique.


The appropriate dosage of Stanozolol varies depending on individual goals, experience level, and gender. For men, a typical oral dosage ranges from 30mg to 50mg per day, while women usually take a lower dose, ranging from 5mg to 10mg per day. It’s crucial to start with the lowest effective dose and gradually increase it while monitoring for any adverse effects.

It’s also essential to note that Stanozolol cycles typically last 6-8 weeks, followed by a post-cycle therapy (PCT) to restore natural testosterone production.

Side Effects:

While Stanozolol offers numerous benefits, it is not without potential side effects. Some common side effects include:

  1. Liver Toxicity: Stanozolol can be harsh on the liver, so it’s essential to use it responsibly and avoid excessive alcohol consumption during its use.
  2. Cardiovascular Issues: It may negatively impact cholesterol levels, increasing the risk of cardiovascular problems.
  3. Virilization (in Women): Women who use Stanozolol may experience virilization symptoms, such as deepening of the voice and increased facial hair growth.
  4. Hormonal Imbalance: Prolonged use of Stanozolol can lead to hormonal imbalances, which can affect mood and libido.
