Winstrol: adverse effects

Low efficiency, high danger

Stanozolol (or Winstrol as it’s called in a commercial setting) is a weak steroid. Weak in terms of opportunities to increase muscle mass in athletes who do, but at the same time very popular and frequent among athletes and bodybuilders. Immediately after its appearance, Winistrol was sold only in the form of low-dose tablets of 2 milligrams or in the form of an aqueous suspension, in which there were only fifty milligrams of active substance per milliliter. Currently, this steroid can be found in any dosage and concentration, and several brands are arranging its release simultaneously. Previously, bodybuilders took Winistrol only before important competitions, because thanks to the substance, it is possible to quickly improve muscle relief and density. In 1995, a series of audio recordings were released by Muscle Media 2000, one of which is dedicated to an interview in which the narrator shares with listeners stories about how the most difficult and successful runners achieved success by taking small doses of Winstrol to prevent muscle loss, which can occur as a result of catabolism, which usually increases after long runs.

Stanozolol is a chemical compound with the following structure: 17-methyl-5-alpha-androstane (3,2-c) pyrazol-17beta-ol and is classified as a controlled anabolic steroid with assigned number 302-96-5. Due to the impressive anabolic-androgenic ratio, this steroid belongs to very anabolic substances. Paradoxically, its effect on increasing strength and muscle mass is not so great. The surprisingly low effectiveness of the drug can be explained by the fact that stanozolol itself is a rather weak androgen, but it is significantly inferior to testosterone in its effectiveness as an anabolic agent.

If we compare stanozolol and testosterone taken in equal doses, stanozolol clearly loses to the opponent in this comparison.

Surprisingly, despite its low effectiveness, stanozolol is still very popular. Perhaps the secret of such popularity of the substance lies in its reputation as an absolutely safe steroid, which, although it does not give a great effect and as quickly as possible, does not cause much harm to the body. Of course, such an opinion is wrong.This steroid, while not causing serious side effects like other strongly androgenic steroids, is still not completely safe. On the contrary: many experts, who have carried out appropriate clinical trials, have come to the conclusion that stanozolol can be considered the most dangerous steroid available in the world today.

So is stanozolol dangerous?

So what can you believe: that stanozolol is virtually safe, or that a more dangerous steroid is hard to find? It should be remembered that the effect of the substance is not yet fully understood and it is quite versatile. At first glance, stanozolol should act on the same principle as other similar substances: causing increased aggression, hair loss, acne. Drugs based on a highly allergenic form of testosterone have this effect. But in reality it doesn’t work like that. As stanozolol is a rather weak androgen, it does not increase the aggressiveness of living beings, but, on the contrary, suppresses it. Similar data are confirmed by a series of experiments performed on animals. The tested specimens became so aggressive that they did not even react in any way to the physical provocations of other men who invaded their personal territory. The same experiment showed that ingested stenozole was not perceived by the male gonads (namely the seminal vesicles) as a substance that replaces testosterone. Rats that were given this steroid for a while started to lose the ability to ejaculate over time and eventually stopped showing any sexual behavior.

The researchers noticed a similar reaction in women who lost sexual receptivity under the influence of the hormone estrogen.

So, judging by the behavioral effects of taking a steroid, stanozolol is more likely to be called an antiandrogen than an androgen. Since the human body’s reactions to certain substances generally do not differ much from the reactions of experimental samples, it can be safely assumed that people taking stanozolol may have impaired sexual susceptibility, which can make them lose their competitiveness. advantage over other individuals.

In addition to the above consequences, taking stanozolol, according to many expert reports, can cause a blockage of the normal function of the brain and various receptor systems, disturbances in the action of anxiolytic and antidepressant drugs. Many athletes who have taken steroids for a period of time report a period of depression that starts abruptly immediately after the drug cycle ends. And experts studying this issue say that stanozolol is contraindicated for people who are highly susceptible to these conditions. Therefore, although stanozolol, unlike other steroid drugs, does not cause the emergence of so-called “steroid drag”, it is still quite dangerous for those who take it, but it is especially dangerous for people with an unstable psyche, who by nature have suicidal tendencies. or is mentally traumatized.

Other adverse effects of taking stanozolol

Unfortunately, the above case is far from the only one of its kind. Even with a review of the literature, evidence can be found for the following incidents associated with stanozolol use: four heart attacks (two of which were fatal), one case of non-life-threatening blood loss, and one case of increased heart rate. . It should be noted that all these cases happened to young people, usually up to the age of thirty.

Among athletes and bodybuilders, it has long been known that taking stanozolol increases the risk of heart attack or myocardial infarction, as the substance lowers “good” cholesterol in the blood and increases the concentration of “bad”. In women taking this steroid, a masculinizing effect may occur, severe bleeding (beginning with a trivial nosebleed and ending with life-threatening esophageal varices) may occur, and the risk of tendon damage increases.

Stanozolol is easily detected by analyzing hair or urine, and the remains of the substance remain in the human body for several months after treatment with the drug ends. This steroid has been shown to suppress the production of testosterone in the body by decreasing the level of androgen-carrying protein in the blood.


Stanozolol, better known as Winstrol, is a popular steroid today. Most athletes who take it are pretty sure that it doesn’t do much harm to the body. While stanozolol has no obvious risk of significant estrogenic and androgenic side effects, it’s not as safe as it sounds. There is a lot of evidence that taking this drug negatively affects the work of various systems in the human body. The results of studies convincingly prove that this steroid substance mimics the effects of the hormone estrogen, reduces libido, can contribute to the onset and development of various mental disorders, weakens healthy aggression and sexual function, often damages the cells of the liver and can also lead to fatal outcome.

Bodybuilders usually take up to one hundred milligrams of stanozolol a day, but even taking six to ten milligrams a day can do irreparable damage to your body. Given that a wide range of steroids are currently known, many of which have far fewer side effects and risks than stanozolol, if you are considering using this drug, ask yourself if it is worth the risk.
