Why does Turinabol remain a controversial compound?
A detailed analysis
Turinabol (or chlorodehydromethyltestosterone) is a modified derivative of Dianabol, designed to provide lean and stable gains without water retention or estrogenic effects. Known for its "clean" profile and good tolerability, it is often referred to as “clean Dianabol,” yet it remains a hepatotoxic oral steroid, banned for human use and still not fully understood in terms of long-term impact.
Historical origin: state-sponsored steroid in East Germany
Turinabol was first synthesized in the 1960s in East Germany (by Jenapharm) to enhance athletic performance without easy detection, as part of the infamous GDR state doping program. It was used in both men and women, including adolescents.
Turinabol: pharmacological characteristics
Half-life: ~16 hours (oral)
Estrogen conversion: none (non-aromatizable)
DHT conversion: none
Liver toxicity: C17α-alkylated → hepatotoxic
Anabolic/androgenic ratio: ~54 / 6 (very mild androgenic effect)
Dosages in bodybuilding
- Beginners/intermediates: 20–40 mg/day for 4–6 weeks
- Advanced users: 50–80 mg/day, up to 8 weeks max
- Common stacks:
- Turinabol + low-dose testosterone (250–300 mg/week)
- Turinabol + Primobolan or Masteron for dry recomposition
Its long half-life allows for once-daily dosing, though some users prefer splitting the dose to smooth out blood levels.
Expected benefits
- Dry, stable muscle gains
- No water retention
- No aromatization → no need for aromatase inhibitors
- Increased strength and muscle hardness
- Good tolerance in men due to low androgenicity
Cautions and side effects
- Hepatotoxicity: Even at moderate doses, it strains the liver. Never exceed 8 weeks.
- Hormonal suppression: Suppresses the HPTA axis — full PCT with Clomid/Nolva is essential.
- Lipid profile: Decrease in HDL, increase in LDL — monitor with blood tests.
- Libido: May drop if used without a testosterone base.
Use in women: extreme caution
Some coaches suggest 2.5–5 mg/day as a lighter alternative to oxandrolone, but virilization is still a serious risk. At just 10 mg/day, adverse effects like acne, deepened voice, body hair growth, and menstrual disruption may appear.
Summary
- Ideal for clean body recomposition
- Steady, lasting muscle gains
- No estrogen conversion
- Moderately hepatotoxic → always use liver protection (TUDCA, NAC, milk thistle)
- Monitor blood lipids and liver enzymes
- Solo cycles require full PCT (Clomid/Nolva)
- Stacks well with testosterone or Primobolan for lean, synergistic results
