Chemical Information and Composition of Turinabol

For researchers, chemists, and wholesale buyers, the molecular architecture of a compound is its most important credential. Turinabol is a masterclass in structural modification. It is a derivative of Testosterone, but specifically, it is a structural hybrid of Dianabol and Clostebol.

Official Chemical Nomenclature

  • IUPAC Name: (8R,9S,10R,13S,14S,17S)-4-chloro-17-hydroxy-10,13,17-trimethyl-1,2,6,7,8,9,11,12,14,15,16,17-dodecahydrocyclopenta[a]phenanthren-3-one
  • Chemical Formula: C20H27ClO2
  • Molecular Weight: 334.89 g/mol
  • CAS Number: 2447-43-4

Structural Composition Breakdown

The chemical structure of Turinabol is what dictates its pharmacological behavior. Here is the breakdown of the specific functional groups attached to its base steroid skeleton (the androstane ring):

  1. The Chlorine Atom at Carbon 4: This is the most crucial modification in Turinabol. The addition of a chlorine atom at the 4th carbon position completely alters the steroid’s interaction with the aromatase enzyme. This structural trait is borrowed from Clostebol. Because of this chloro-substitution, the enzyme cannot bind to the molecule to convert it into an estrogen. Therefore, Turinabol does not aromatize under any circumstances.
  2. Methyl Group at Carbon 1: This modification is borrowed from Dianabol (Methandrostenolone). The 1-methyl group significantly enhances the anabolic potency of the molecule, allowing it to strongly bind to androgen receptors and promote protein synthesis.
  3. 17-Alpha Alkylation (17aa): To survive the first pass through the liver and remain bioavailable when taken orally, Turinabol features a methyl group at the 17th carbon position. Without this 17aa modification, the steroid would be destroyed by the liver before it could enter the bloodstream and exert its effects.

Physical and Chemical Properties

  • State at Room Temperature: Solid (Crystalline Powder)
  • Color: Typically white to off-white
  • Solubility: Practically insoluble in water; soluble in organic solvents such as DMSO, ethanol, acetone, and chloroform.
  • Melting Point: Approximately 144°C to 146°C.

Pharmacokinetics

  • Route of Administration: Oral
  • Half-Life: The biological half-life of Turinabol is approximately 16 hours. This relatively long half-life allows for a stable blood plasma level with a twice-daily dosing protocol, though some advanced users opt for a single daily dose due to its active metabolites.
  • Detection Time: Turinabol is notorious for its long detection time in anti-doping tests. Because it is heavily metabolized in the liver, some of its metabolites are highly resistant to breakdown and can be detected in urine for up to 6 to 8 weeks after the last dose. In some cases, using highly sensitive Carbon Isotope Ratio Mass Spectrometry (CIRMS), metabolites have been detected months later. This long detection window is a critical consideration for tested athletes.
