What is Stanozolol?

Stanozolol is an anabolic steroid derived from male hormone dihydrotestosterone (DHT), commonly sold under the brand name “Winstrol”. It can be taken either orally or through intramuscular injections.

Why use Stanozolol?

Stanozolol has legitimate medical applications such as stimulating collagen production and suppressing the anti-anabolic properties of the hormone cortisone. It is approved for human use under the supervision of a medical professional to treat such conditions as anaemia and hereditary angiodema, and has similar applications in veterinary medicine. However, Stanozolol is sometimes abused to promote muscle gain and fat loss.

Stanozolol Side Effects

Stanozolol, like other anabolic steroids, has a an array of serious and life threatening side effects. These symptoms may occur suddenly and without warning in otherwise healthy, fit, young people, and they may be irreversible.

Side effects include:

  • High blood pressure, which is a risk factor for heart and kidney disease (4);
  • Decreased HDL (good) cholesterol and increased LDL (bad) cholesterol
  • can lead to coronary heart disease and atherosclerosis (5). In one study, the effects of a single dose of stanozolol were still visible in raised blood cholesterol readings one month later (3).
  • Changes to blood clotting, which can cause stroke (2, 5)
  • Enlargement of the wall of the heart chamber responsible for pumping blood to the body can result in reduced blood flow and heart failure (6).
  • Hepatitis (7) and Liver cancer (8)
  • A range of hormonal disturbances, causing symptoms such as severe acne (9), baldness (10), testicular shrinkage, long term suppression of the body's ability to produce normal levels of testosterone, infertility, gynaecomastia (man boobs) (11), increased risk of testicular cancer (12) and development of male features in women (13).
  • Mental disturbances such as aggression and body dysmorphia (13) and psychological dependence. Mental and physical withdrawal symptoms are common (14).

Finally, steroids sold illegally are not subject to quality control, so may be out of date, contaminated, produced under poor conditions, or not what they say they are. One study showed that nearly one third of steroids on the market are counterfeit, and nearly half of these contained a different active ingredient to that stated on the label (1).

Alternatives to Stanozolol

There are a number of effective and legal substances that support the body to increase its own testosterone production safely within the natural range. Some ingredients to look out for include:

  • Tribulus -  This plant that has been used historically in many cultures to enhance libido, mood and muscle growth. Modern formulations such as Massive Muscle Fuel stack tribulus with other natural testosterone boosters. Tribulus is the most popular testosterone support ingredient currently on the market.
  • D-aspartic acid - This amino acid has shown some extremely promising results as a test booster, raising testosterone production in adult males by 42% in one study (15). Ronnie Coleman Testogen XR is an example of a popular testbooster containing D-aspartic acid.
  • Aromatase inhibitors - Also known as estrogen blockers and anti estrogen supplements. These substances inhibit the reaction that changes testosterone to oestrogen in the body. Products such as BPI A-HD combine a number of safe and effective plant extracts and are very popular.
