Winstrol is generally not preferred for building mass as it is highly anabolic and very slightly androgenic, an oral Steroid such as Dianabol is usually a better choice for people wanting to bulk up. Due to its ability to dramatically lower SHBG it can be used in a bulking cycle as a means to make other hormones more efficient, increase free testosterone and even solidify gains to a stronger degree but most of the people will find other steroids to be far more beneficial than winstrol in the long run. However some people are very sensitive to side effects of certain Steroids such as Dianabol, and would rather use Winstrol in a bulking cycle, while the weight gain wont be as dramatic as with Dianabol, with a proper high calorie diet, you can still see good results.
Dianabol is not an extremely androgenic steroid, its androgenicity has been structurally reduced, but androgenic side effects are still possible. Such side effects of Dianabol use include acne, accelerated hair loss in those predisposed to male pattern baldness and body hair growth. Most men should not have a problem with such effects, response will be the final dictator, but most will remain clear. Although the odds are in your favor, such effects are brought on by Methandrostenolone being metabolized by the 5-alpha reductase enzyme. This is the same enzyme responsible for the reduction of testosterone to dihydrotestosterone, but the overall conversion here will result in very low amounts of dihydromethandrostenolone. This tells us 5-alpha reductase inhibitors like Finasteride that are often used to combat androgenic side effects will have very little if any affect on Dianabol.
Despite its reduced androgenicity, Dianabol can promote virilization symptoms in women. Such symptoms include body hair growth, a deepening of the vocal chords and clitoral enlargement. It is possible for some women to use this steroid without virilization symptoms with extremely low doses, but the odds are not favorable. Most all women should choose anabolic steroids with less translating androgenic activity to meet their needs.
