The 17α-methylation of the steroid does allow it to pass through the liver with only a small portion of it broken down (hence causing the aforementioned damage to the liver) allowing it to be effective when taken orally. It also has the effect of decreasing the steroid's affinity for sex hormone binding globulin, a protein that de-activates steroid molecules and prevents them from further reactions with the body. As a result, methandrostenolone (metandienone) is significantly more active than an equivalent quantity of testosterone, resulting in rapid growth of muscle tissue. However, the concomitant elevation in estrogen levels - a result of the aromatization of methandrostenolone - results in significant water retention. This gives the appearance of great gains in mass and strength, which prove to be temporary once the steroid is discontinued and water weight drops. Because of this, metandienone is often used by bodybuilders only at the start of a "steroid cycle", to facilitate rapid strength increases and the appearance of great size, while compounds such as testosterone or nandrolone with long acting esters build up in the body to an appreciable amount capable of supporting anabolic function on their own.
