As we discussed above, Dianabol carries a strong aromatizing nature, and is a C17-aa anabolic steroid; as such, its side-effects will revolve around these factors. As an aromatizing steroid, this means there can be a testosterone to estrogen conversion, and if estrogen levels go to high it can lead to some complications. When estrogen levels increase, the hormone can attach to the receptors and cause gynecomastia (male-breast enlargement) and it can also promote excess water retention and high blood pressure; Dbol is notorious for promoting high blood pressure. Needless to say, if you already suffer from high blood pressure you should not touch this steroid, but if it's healthy you'll need to ensure it stays this way. For this reason, in-order to combat and avoid these estrogenic side-effects of Dbol, the use of an Aromatase Inhibitor (AI) is often advised. It shouldn't be too hard to see how this can help; after all, an AI inhibits aromatase, but it goes a step further by reducing the body's total estrogen levels. Of course, and this cannot be overstressed, you must keep your doses at a responsible level; most will need at least 20mg per day for any anabolic promotion, with a maximum dosing of 50mg per day. It should be noted; if you've never used this steroid before, you should not start with a high end dose; start low and see how you respond.
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.
