Winstrol is a popular brand name for the anabolic steroid stanozolol. Winstrol is a derivative of dihydrotestosterone, although its activity is much milder than this androgen in nature. It is technically classified as an anabolic steroid, shown to exhibit a slightly greater tendency for muscle growth than androgenic activity in early studies. While dihydrotestosterone really only provides androgenic side effects when administered, Winstrol instead provides quality muscle growth.
Since stanozolol is not capable of converting into estrogen, an anti-estrogen is not necessary when using this steroid, gynecomastia is not a concern even among the most sensitive individuals. Since estrogen is also the cause of water retention, instead of bulk look, Winstrol produces a lean, quality look with no fear of excess subcutaneous fluid retention. This makes it a great steroid to use during cutting cycles, when water and fat retention are a major concern. It is also very popular among athletes in combination strength/speed sports such as Track and Field
