Winstrol, also called Winny, is another well-known steroid, and among the few that are both injectable and oral. It is used mostly in combination with other steroids, and not by itself.

It is the most commonly known brand name for Stanozolol, which itself is a derivative of dihydrotestosterone (DHT), although it has lower androgenic activity. It is a steroid that promotes mass gains rather than androgenic effects, compared to DHT, which has strong androgenic effects but does not add mass to the muscles. Winstrol is a steroid used predominantly in defining and sharpening cycles. It is very rarely used in muscle mass accumulation cycles. Which means that it is especially a steroid used during bodybuilding cutting periods and by fitness models. Medically, it does not help too much to treat anemia, so its role in increasing body mass is low. But it is useful for treating osteoporosis and is often given for burns and to those who have undergone long-term corticosteroid treatments. It is also used for children with growth deficits and for some forms of breast cancer. It’s one of the most used steroids in medicine.

Recently, it has begun to be used during steroid treatments in very small doses to reduce sex hormone binding globulin (SHBG), the testosterone transport protein. This protein binds to testosterone and disables it. The lower the levels of SHBG, the freer testosterone in the blood that has its anabolic and androgenic features. Even in small doses, Winstrol reduces with 50% SHBG, and this in just a few days.

Winstrol is illegal for unapproved use in human because of its side effects that may be really serious for many people.

Estrogenic side effects:                                              

With Winstrol, estrogen side effects are impossible. It does not lead to water and fat retention and does not cause gynecomastia.

Androgenic side effects:

Winstrol is not a very androgenic steroid but can cause androgenic side effects. There may be acne and hair loss, but especially in those who are genetically predisposed. It can cause erectile dysfunction if it is used without an androgen such as testosterone.

As Winstrol is already DHT, Proscar will not work to reduce androgenic side effects.

In women, it can cause virilization (hair growth, voice thickening, clitoral enlargement), especially at doses above 5 mg /day. On the appearance of any virilization sign, the dose should be discontinued immediately.
