Dianabol

Methandrostenolone / dbol · Anabolic-androgenic steroid (oral)

Research reference only. Pepdex does not sell, supply or track this compound, and nothing here is guidance to use it — this page exists so the evidence and the risks are visible.

What it is

The original bodybuilding steroid — the oral that built the golden era and still the most common first (and most casually taken) AAS because it is cheap, oral, and fast. Rapid size and strength, much of it water.

What human evidence shows

Old, sparse clinical record; effectiveness for rapid mass is not in dispute and never was. What the decades established instead is the cost structure: heavy aromatization, liver strain, and blood-pressure elevation arriving within weeks.

Risks

17-alpha-alkylated liver load, aggressive aromatization (gyno and water/BP spikes that hit fast), lipid damage, full suppression. Its danger is sociological as much as pharmacological: it is the steroid people take WITHOUT a plan, because a bottle of pills feels casual in a way a vial does not.

Stacking interactions
