Then we have liver toxicity, and if you’re a normal and sane human being this might sound pretty scary. As stated early on, as a C17-aa steroid Dianabol carries a liver toxic nature. It is not as toxic as excess alcohol consumption and not as toxic as many over the counter medications, but it still carries a strong toxic nature. For this reason, again, responsible use must be implored. If it is, while liver enzyme levels will increase, because the liver rejuvenates remarkably well, liver enzyme levels will return to normal once use is discontinued, assuming no additional stress has been added to the liver. These are the facts regarding the side-effects of Dbol, and any Dianabol reviews that stray are again not worth your time.
Although the original pharmaceutical steroid Dianabol did have some adverse or annoying side effects such as possible damage to the liver, Legal Dianabol does not cause such adverse effects. For instance, the pharmaceutical steroid could also cause gynecomastia, which is a sudden decrease in the male hormone, testosterone, and a resulting increase of estrogen, the female hormone, in the body. This can result in enlarged breast tissue in some men and often causes pronounced water retention, which can be a hindrance to engaging in long periods of strenuous physical activity.
The most commonly used AAS in medicine are testosterone and its various esters (but most commonly testosterone undecanoate , testosterone enanthate , testosterone cypionate , and testosterone propionate ),  nandrolone esters (most commonly nandrolone decanoate and nandrolone phenylpropionate ), stanozolol , and metandienone (methandrostenolone).  Others also available and used commonly but to a lesser extent include methyltestosterone , oxandrolone , mesterolone , and oxymetholone , as well as drostanolone propionate , metenolone (methylandrostenolone), and fluoxymesterone .  Dihydrotestosterone (DHT; androstanolone, stanolone) and its esters are also notable, although they are not widely used in medicine.  Boldenone undecylenate and trenbolone acetate are used in veterinary medicine .
