Methandrostenolone is a derivative of testosterone, modified so that the androgenic (male) properties of the hormone are reduced and its anabolic properties (tissue construction) preserved. Having a lower relative androgenic level than testosterone, methandrostenolone is classified as an “anabolic” steroid, although a distinctly androgenic side is always present. This drug has been designed and is primarily sold as an oral medication, although it can also be found in a number of injectable veterinary solutions. Dianabol is today, and has always been, the most commonly used oral anabolic / androgenic steroid used for performance enhancement purposes.
Studies have shown that taking an oral anabolic steroid with food may decrease its bioavailability. This is caused by the fat-soluble nature of steroid hormones, which may allow some of the drug to dissolve with undigested dietary fat, thus reducing its absorption from the gastrointestinal tract. For maximum use, oral forms of stanozolol should be taken on an empty stomach.
For physical or performance-enhancing reasons, the drug is also used intermittently, with cycles that typically last between 6 and 8 weeks, followed by 6-8 weeks of rest. Although a low dose of 5 mg daily may be effective in improving performance, athletes generally take much higher amounts. A daily dosage of 15-30 mg is the most common, and usually produces very dramatic results.
