Turinabol (Chlorodehydromethyltestosterone 10 mg)

Turinabol (Chlorodehydromethyltestosterone 10 mg) is Evolve Biolabs' mild, non-aromatising oral, supplied as 50 tablets in sealed blister strips. It was engineered to deliver anabolic activity with minimal oestrogenic effect, and it remains a reference compound for dry, lean-gain research.

What Turinabol Is

Chlorodehydromethyltestosterone, universally known as Turinabol or Tbol, is a 17-alpha-alkylated oral anabolic derived from methandienone. A chlorine atom at carbon four and an additional double bond in the A-ring block the aromatisation pathway, so the compound does not convert to oestradiol. That single structural change produces a much drier profile than Dianabol while preserving oral bioavailability. Evolve Biolabs supplies it at the classic 10 mg strength.

The History of Turinabol

Turinabol was developed in the early 1960s by VEB Jenapharm in East Germany and marketed as Oral-Turinabol. It became notorious through the state-sponsored doping programme of the 1970s and 1980s, where it was administered to athletes, frequently without their knowledge. After German reunification the compound was withdrawn, and its history became a case study in the ethics and governance of performance enhancement.

How It Works

The molecule binds the androgen receptor and promotes protein synthesis and nitrogen retention, producing gains without oestrogen-driven water retention. Because it is 17-alpha-alkylated, it survives first-pass hepatic metabolism and is orally active, but that same modification places metabolic stress on the liver. It is metabolised into long-lived urinary metabolites that remain detectable for weeks after the last dose, a property that has made it a frequent target in anti-doping retesting.

What the Research Shows

• Turinabol was studied clinically as an anabolic agent in the 1960s.
• Its non-aromatising structure and dry profile are well documented.
• The East German programme generated extensive documentation of its long-term use.
• Anti-doping research has characterised its persistent urinary metabolites.

Research Context

Turinabol occupies an unusual place in the literature because the East German doping files created a rare longitudinal record of exposure in athletes. Those archives have allowed researchers to examine health outcomes decades after use, something that is rarely possible with anabolic compounds. At the same time, analytical chemists have mapped its metabolites in detail, and the long detection window is now a standard example in doping-control teaching.

Strength, Pack and Authentication

Each tablet contains 10 mg of chlorodehydromethyltestosterone, with 50 tablets per pack. The tablets are sealed in moisture-resistant blister strips inside a printed, tamper-evident carton that states the compound, strength and tablet count. A verification code on the packaging can be checked against Evolve Biolabs' records, and the blister format keeps every tablet protected until use.
