Stanoxyl, also known by its generic name Stanozolol, is an oral anabolic steroid manufactured by Kalpa Pharmaceuticals. It is a synthetic derivative of testosterone, specifically designed to promote muscle growth and enhance athletic performance. Stanozolol is commonly used in the treatment of hereditary angioedema, which causes episodes of swelling in the face, extremities, genitals, bowel wall, and throat. However, its most popular use is among athletes and bodybuilders who seek to gain lean muscle mass and improve physical strength and endurance. Stanozolol is appreciated for its ability to provide significant anabolic effects with minimal androgenic side effects.


While Stanoxyl can be highly effective for muscle growth and performance enhancement, it is not suitable for everyone. Contra-indications include:

  1. Pregnancy and Breastfeeding: Stanozolol is not recommended for women who are pregnant or breastfeeding due to the risk of virilization and other potential adverse effects on the fetus or infant.
  2. Prostate Cancer: Men with prostate cancer should avoid using Stanozolol, as it may exacerbate the condition.
  3. Breast Cancer in Men: Men with breast cancer should not use this drug due to its potential to stimulate cancer cell growth.
  4. Severe Liver Disease: Individuals with significant liver impairment should avoid Stanozolol because it is hepatotoxic.
  5. Allergic Reactions: Anyone who has had an allergic reaction to Stanozolol or any of its components should not use this drug.
  6. Nephrotic Syndrome: People with kidney disease, particularly nephrotic syndrome, should avoid Stanozolol due to its potential to worsen kidney function.


Proper administration of Stanoxyl is crucial to achieve the desired muscle growth and performance enhancement effects while minimizing potential risks. The recommended guidelines include:

  1. Dosage: For muscle mass gain, the typical dosage for men ranges from 25 mg to 50 mg per day, while women usually take a lower dosage, around 5 mg to 10 mg per day. It is essential to start with a lower dose to assess tolerance.
  2. Cycle Length: Stanozolol cycles typically last between 6 to 8 weeks. Prolonged use beyond this period is not recommended due to the risk of liver toxicity.
  3. Consistency: Take the drug at the same time each day to maintain stable blood levels.
  4. Stacking: Stanozolol can be stacked with other anabolic steroids such as testosterone or trenbolone to enhance muscle-building effects. However, stacking should be done cautiously and under professional guidance to avoid adverse effects.

Medical Action

Stanozolol works through several mechanisms to promote muscle growth and enhance athletic performance:

  1. Anabolic Effects: Stanozolol has a strong anabolic effect, which means it promotes protein synthesis and nitrogen retention in muscles. This leads to increased muscle mass and strength.
  2. Androgenic Effects: While it has androgenic properties, these are relatively mild compared to other anabolic steroids. This makes it suitable for users who want to avoid significant androgenic side effects.
  3. Red Blood Cell Production: Stanozolol stimulates the production of red blood cells, which improves oxygen delivery to muscles during workouts, enhancing endurance and recovery.
  4. Fat Loss: It helps reduce body fat by increasing metabolic rate and promoting lipolysis, which is the breakdown of stored fats into usable energy.
  5. Vascularity: Users often experience enhanced vascularity, giving muscles a more defined and ripped appearance due to the reduction in water retention.


Using Stanoxyl requires adherence to several precautions to ensure safe and effective use:

  1. Regular Monitoring: Regular blood tests to monitor liver function, cholesterol levels, and hormone levels are essential to avoid potential complications.
  2. Liver Health: Since Stanozolol is hepatotoxic, users should avoid alcohol and other substances that can further strain the liver. Taking liver support supplements like milk thistle can be beneficial.
  3. Cholesterol Levels: Stanozolol can negatively impact cholesterol levels, so maintaining a heart-healthy diet rich in omega-3 fatty acids is important.
  4. Prostate Health: Regular prostate exams are advised for men, particularly older individuals, to monitor for any potential prostate-related issues.
  5. Hydration: Staying well-hydrated is important to support overall health and minimize the risk of muscle cramps and kidney strain.
  6. Individual Response: Users should start with a lower dose to assess individual tolerance and response to the drug.

Side Effects

While Stanoxyl is effective for muscle growth, it can cause side effects ranging from mild to severe:

Common Side Effects

  1. Acne: Increased androgen levels can lead to acne breakouts.
  2. Hair Loss: Men predisposed to male pattern baldness may experience accelerated hair loss.
  3. Mood Changes: Some users may experience mood swings, aggression, or irritability.
  4. Oily Skin: Androgenic effects can lead to increased oil production in the skin.
  5. Joint Pain: Some users report joint pain or discomfort, which can be due to the drying effect of Stanozolol on the joints.

Severe Side Effects

  1. Liver Toxicity: Prolonged use or high doses can lead to liver damage, including liver tumors or hepatitis.
  2. Cardiovascular Issues: Stanozolol can negatively affect cholesterol levels, increasing the risk of cardiovascular diseases such as heart attacks or strokes.
  3. Suppression of Natural Testosterone: Long-term use can suppress natural testosterone production, leading to hormonal imbalances and requiring Post Cycle Therapy (PCT).
  4. Gynecomastia: Improper use can lead to the development of gynecomastia, which is the enlargement of male breast tissue.
  5. Hypertension: Increased blood pressure can occur, necessitating regular monitoring and management.


In the case of an overdose, immediate medical attention is necessary. Symptoms of Stanozolol overdose may include:

  1. Severe Nausea and Vomiting: Excessive intake can cause severe gastrointestinal distress.
  2. Dizziness and Fainting: Overdosage can lead to extreme dizziness and potential fainting spells.
  3. Breathing Difficulties: Respiratory issues may arise in severe cases.
  4. Liver Damage: Overdose can exacerbate liver toxicity, leading to serious liver conditions.

Treatment for overdosage is supportive and symptomatic, focusing on stabilizing the patient and addressing specific symptoms. There is no specific antidote for Stanozolol overdose.


Stanoxyl from Kalpa Pharmaceuticals, also known as Stanozolol, is a potent oral anabolic steroid that offers significant benefits for muscle growth and athletic performance enhancement. Its strong anabolic properties, combined with relatively mild androgenic effects, make it a popular choice among bodybuilders and athletes. By promoting protein synthesis, nitrogen retention, and red blood cell production, Stanozolol helps users achieve increased muscle mass, strength, and endurance.

However, the use of Stanoxyl requires careful consideration of its contra-indications, potential side effects, and necessary precautions. Proper administration, including dosage management and regular health monitoring, is crucial to maximizing its benefits and minimizing risks. Regular health check-ups, a balanced diet, and liver support supplements can help users safely harness the advantages of Stanozolol while mitigating associated risks. By adhering to these guidelines, individuals can effectively use Stanoxyl to support their bodybuilding goals and maintain overall health and well-being.
