Because steroids are lipophilic, they diffuse easily through the cell membranes, and therefore have a very large distribution volume. In their target tissues, steroids are concentrated by an uptake mechanism which relies on their binding to intracellular proteins (or " receptors ", see below). High concentration of steroids are also found in adipose tissue, although this is not a target for hormone action. In the human male, adipose tissue contains aromatase activity, and seems to be the main source of androgen-derived estrogens found in the circulation. But most of the peripheral metabolism occurs in the liver and to some extent in the kidneys, which are the major sites of hormone inactivation and elimination, or catabolism (see below).
It must be noted possible side-effects such as Gynecomastia , water retention, high blood pressure and high cholesterol are all a possibility with this cycle as both Testosterone and Dianabol aromatize and cause a buildup in estrogen . If you’re nipples begin to get sore while on cycle you might try supplementing with 10mg of Nolvadex per day. If this does not work you are going to need an Aromatase Inhibitor such as Arimidex or Letrozole ; every other day of either should suffice. Further, if you keep your diet clean you will largely protect from water retention; some will occur if you are really trying to bulk but limit your excess calories only to what you absolutely need and avoid overeating carbohydrates. Further, keeping your diet clean is also good for your blood pressure and cholesterol; moreover, consuming plenty of Omega-3 Fatty Acids can greatly serve you here.
