Dianabol is a powerful steroid that can result in a great buildup of muscle mass and strength in a relatively quick period of time. Dianabol is commonly combined with testosterone products to improve gains in muscle mass, strength and improve muscle pumps. A weight gain of 2-4 pounds each week for six weeks is normal when using Dianabol, and this increase in weight results from the growth of muscle fibers, as well as water retention. Dianabol is liver toxic if used in high doses or over extended periods of time, so it is important to understand your body's propensity for side effects and start slowly. Dianabol is a steroid for the slightly more advanced athlete, and when stacked with an injectable steroid, less Dianabol is needed.
