Also known as: Tbol, OT, Oral Turinabol

A derivative of Dianabol modified to reduce oestrogenic activity. Produces slow, lean gains without water retention. Often presented as 'safe' but still carries all the risks of oral steroid use.

Lower/Moderate Risk

What it is

A derivative of Dianabol, modified to reduce oestrogenic activity. Famously used in the East German state doping programme in the 1970s and 80s. 17-alpha-alkylated for oral bioavailability. Does not aromatise.

What it does

Produces slow, lean gains without water retention. Does not aromatise. Often considered a 'milder' alternative to Dianabol, though this label can be misleading. Provides moderate increases in strength and lean tissue.

Typical dosages

20-50mg per day is commonly reported. Cycles are typically 6-8 weeks. Should be run with a testosterone base. This is not a recommendation; it is what is commonly reported.

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

  • Hepatotoxic (as with all 17-alpha-alkylated oral steroids)
  • Negative impact on cholesterol
  • Suppression of natural testosterone
  • Mild androgenic effects (acne, hair thinning)
  • Potential cardiovascular strain

Specific risks

  • False reputation: often presented as a 'safe' oral steroid. This is misleading. It is milder than Dianabol or Anadrol but still carries all the risks of oral steroid use, including liver stress and cholesterol impact
  • Long-term data: the East German doping programme provides the most extensive (albeit involuntary) long-term data on this compound, and the health outcomes were poor. Many former athletes experienced lasting cardiovascular and liver damage
  • Liver toxicity: while milder than some orals, the hepatotoxic effect is still present and requires monitoring

What to watch for

  • Liver values on blood work (ALT, AST)
  • Cholesterol changes, particularly HDL suppression
  • Fatigue or lethargy (can indicate liver stress)
  • Do not stack with other oral steroids
