What it is

Dianabol (Methandrostenolone) was one of the first oral steroids developed, in the late 1950s. It was originally created for US Olympic athletes. It remains one of the most widely used oral steroids due to its dramatic and rapid effects on muscle mass and strength. It is a derivative of testosterone with modifications that allow it to survive oral ingestion.

What it does

Dianabol rapidly increases protein synthesis and glycogenolysis. Users typically report significant weight gain in the first few weeks of use, often 5–10kg, though much of this is water retention. Strength increases are dramatic and fast. It aromatises heavily (converts to oestrogen), which contributes to both the mass gains and the side effects.

Typical dosages

20–50mg per day is commonly reported. Some users 'kickstart' longer injectable cycles with 4–6 weeks of dianabol at the beginning while waiting for the injectable to reach peak levels. As with all orals, duration should be limited due to liver impact. Using it without a testosterone base is widely considered inadvisable in harm reduction communities.

These figures reflect commonly reported usage in harm reduction communities. They are not recommendations. There is no safe dose of anabolic steroids for non-medical use. Start low and monitor your health through blood work.

Side effects

Significant water retention and bloating
Gynecomastia risk (high aromatisation rate; oestrogen management is critical)
Liver strain (hepatotoxic, more so than anavar)
High blood pressure (due to water retention and increased blood volume)
Acne
Suppression of natural testosterone production
Back pumps (painful lower back pumps during exercise)

Specific risks

Liver: dianabol is C17-alpha alkylated to survive liver processing, which makes it hepatotoxic. Liver values (ALT, AST) should be monitored
Cardiovascular: the combination of water retention, blood pressure increase, and cholesterol impact makes this a significantly cardiovascular-stressful compound
Oestrogen management: without an aromatase inhibitor, gynecomastia can develop quickly. However, crashing oestrogen with too much AI is also dangerous
Rapid weight changes: the fast weight gain and loss (when stopping) can be psychologically difficult and may drive continued use

What to watch for

Blood pressure: monitor daily if possible. Above 140/90 is a concern
Nipple sensitivity or swelling (gynecomastia developing)
Dark urine or pale stools (signs of liver stress)
Rapid weight gain beyond what is expected (excessive water retention)
Difficulty breathing when lying down (can indicate severe fluid retention)

Other compounds

Testosterone

Lower/Moderate Risk

The base of almost every steroid cycle. Testosterone is the primary male sex hormone and the most commonly used anabolic steroid.

Trenbolone

Extreme Risk

One of the most powerful and dangerous steroids in common use. Extremely potent but with a severe side effect profile that makes it unsuitable for most users.

Anavar (Oxandrolone)
