As a DHT derivative, oxymetholone is not a substrate for aromatase and hence cannot be aromatized into estrogenic metabolites .  However, uniquely among DHT derivatives, oxymetholone is nonetheless associated with relatively high estrogenicity, and is known to have the potential to produce estrogenic side effects such as gynecomastia (rarely) and water retention .     It has been suggested that this may be due to direct binding to and activation of the estrogen receptor by oxymetholone. 
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.
The Oral Steroids Winstrol & Anavar:The Oral Steroids Winstrol & Anavar:The Oral Steroids Winstrol & Anavar:vWhile both of these oral steroids can be used for both bulking and cutting, most male anabolic steroid users will be better served using them as a part of a leaning or cutting cycle. Neither drug will produce abundant gains in size but they serve as a well refined tool in terms of holding on to strength as well as helping produce a harder physique. As it pertains to Winstrol, some may find a more suitable use during an off-season period in conjunction with other anabolic steroids; an increase in strength is always a welcomed attribute but do not expect to see the scale move upward in serious fashion due to Winstrol use. The same cannot be said of Anavar; most men will find Anavar suited only for cutting cycles but be aware, there are far better suited anabolic steroids we can use for this purpose but don’t be fooled, Anavar does have a place in both bulking and cutting cycles. Anavar is not only one of the best oral steroids for females it is one of the best anabolic steroids for female’s period. Due to its very mild effects Anavar is one of the safest anabolics a woman can use and in general at a very low dose and still see fantastic results. Anavar can be successfully used by women during both bulking and cutting cycles quite well.
