Winstrol (Stanozolol) – Benefits and Side-effects

Share the love

Winstrol is the commercial name for the anabolic steroid Stanozolol. This steroid is available in both oral and injectable form and is one of the most popular steroids used today, after testosterone and Dianabol.

Stanozolol is an anabolic steroid that is derived from Dihydrotestosterone (DHT). It was first produced in the early 1960s by Sterling-Winthrop labs to treat medical conditions such as anemia and osteoporosis. It was not long before bodybuilders and athletes took notice of the benefits resulting from using Winstrol.


While the dosage of Stanozolol is rather low for treating medical conditions, when it comes to building muscle and increasing performance, a dosage of 50 to 100mgs a day is not uncommon. At these high dosages, bodybuilders and athletes can expect rapid gains in strength and muscle mass.


There are many reasons as to why Winstrol has become such a popular anabolic steroid. Below you will find some of the top ones.

It Does Not Aromatize

Winstrol is one of the few anabolic steroids that does not convert to estrogen. For this reason, estrogen related side effects such as water retention and gynecomastia are not a concern when using this steroid.

Lean Muscle Mass

With many anabolic steroids, much of the weight gained is due to water retention. So while you may gain 10 kgs in a month from using Dianabol, the majority of this weight is water and will disappear soon after the cycle is over. Whereas with Winstrol since there is no water retention, all weight gained is lean muscle tissue.

The lean muscle gains associated with Winstrol are so impressive that this steroid is usually the number one choice when doing a cutting cycle.

Muscle Hardness

This benefit can be attributed to the fact that Winstrol does not aromatize. Moreover, as mentioned above, since there is no water retention when using this steroid, the muscles will usually increase in hardness as body fat percentage lowers during the cutting cycle.

Increased Performance

Winstrol increases strength and only adds on lean muscle mass which is the perfect combination for athletes who are looking to get faster and stronger. Athletes who compete in a set weight class or who compete in sports where speed is required would not benefit from using an anabolic steroid that increases their body weight by too much. Increasing body weight would lead to them being too heavy to compete in a particular weight class or being too slow to compete in a race where speed is required.

One famous case of an athlete using steroids to enhance their performance was Ben Johnson who dominated the 100m sprint at the 1988 Olympic Games. It was later discovered that he had been using Winstrol.


Although Winstrol is often mild when compared to many other anabolic steroids, there are still side-effects that may occur when using this steroid, especially at higher dosages. There are a lot of different side effects that may occur when using any steroid; however, we will only be going over some of the more common ones associated with Winstrol.

Liver Damage

This is one of the more severe side effects. As with many other oral anabolic steroids, Winstrol is a C17-alpha alkylated steroid. This means that Winstrol has an added methyl group at the 17th carbon which allows it to enter the bloodstream without being destroyed by the liver. While the addition of a methyl group makes Winstrol an effective anabolic steroid, it also puts a lot of strain on the liver.

To reduce the risk of liver damage, don’t take high dosages of this steroid, keep cycles to a maximum of 6 weeks, drink plenty of water, and avoid alcohol at all costs. Blood tests to check liver values during and after the cycle are also very important.


Winstrol as with all anabolic steroids messes with your hormones which results in oily skin. While many people do not get acne while using this anabolic steroid, some people will suffer from this side-effect especially when taking larger dosages. If you suffered from acne when you were a teenager, then chances are you will get acne when using this or any other anabolic steroid.

Hair Loss

Not everyone experiences this side effect. In fact, only people who are genetically predisposed to male pattern baldness (MPB) suffer from hair loss when using anabolic steroids. Male pattern baldness occurs in males when DHT levels rise. The DHT gets attached to hair follicles causing them to miniaturize thus decreasing the lifespan of each follicle.

It is believed that anabolic steroids cause DHT to increase in the body which speeds up male pattern baldness. Winstrol is notorious for speeding up male pattern baldness due to it being derived from dihydrotestosterone, the exact hormone that causes this type of hair loss.

If you are genetically predisposed to male pattern baldness and like your hair, you should avoid using any type of anabolic steroid at all costs, because you will lose hair.

Joint Pain

Winstrol causes the loss of synovial fluid, which is a fluid found in the cavities of synovial joints. The primary role of this fluid is to reduce the amount of friction caused during the movement of the synovial joints. The loss of this fluid results in joint pain. This side effect is quite common and can often be painful.

Testosterone Suppression

Like with all anabolic steroids, Winstrol will suppress your body’s natural testosterone production. This can result in many different issues such as testicular atrophy, loss of energy, and depression. To help combat this problem, a PCT should be started once the Winstrol cycle has come to an end.

An effective PCT will help speed up your body’s ability to start producing testosterone again, which will reduce the risk of side-effects related to low testosterone levels.
