Turinabol (4-Chlorodehydromethyltestosterone)

Active Substance: Turinabol

steroidoral

Description

Turinabol (4-Chlorodehydromethyltestosterone) is an anabolic-androgenic steroid (AAS).

1. Detailed Explanation and Other Names

  • Chemical Name: 4-Chlorodehydromethyltestosterone (CDMT)

  • Brand/Other Names: Oral-Turinabol, T-bol, Dehydrochloromethyltestosterone, 4-Chloromethandienone.

  • Description: Turinabol is an oral anabolic steroid derived from Metandienone (Dianabol) but with a modification: the addition of a chlorine atom at the 4-position of the steroid structure.

  • Key Characteristic: This modification prevents the steroid from being converted (aromatized) into estrogen. It was originally developed in East Germany and patented in 1961, known for promoting muscle growth and athletic performance with a reportedly lower incidence of androgenic side effects compared to many other steroids.

2. Benefits, Side Effects, and Pros & Cons

Category Benefits (Reported in performance enhancement) Side Effects (Risks of use/misuse) Pros (Relative to other AAS) Cons (Inherent risks/drawbacks)
Effects Promotes lean muscle mass gain and strength. Hepatotoxicity (Liver damage): As a C17-α alkylated oral steroid, it poses a high risk to the liver. Does not aromatize (convert to estrogen), minimizing water retention, gynecomastia, and bloat. Significant risk of Hepatotoxicity (Liver damage).
  Enhances athletic performance and endurance (due to increased red blood cell production). Cardiovascular Issues: Can negatively impact cholesterol levels (lowering HDL "good" cholesterol and raising LDL "bad" cholesterol), increasing risk of heart attack/stroke. Lower Androgenicity: Reduced risk of androgenic side effects compared to many other AAS. HPTA Suppression: Significantly suppresses natural testosterone production.
  Harder, quality muscle gains without significant water retention ("dry gains"). Androgenic Effects: Acne, hair loss (male-pattern baldness), body hair growth, and potentially irreversible virilization in women (deepening of voice, clitoral enlargement). Promotes slow, consistent, quality gains. Potential for permanent side effects, especially in women.
  Used in cutting cycles to help preserve muscle mass during a caloric deficit. Psychological: Mood swings, aggression ("roid rage"), depression.   Banned Substance: Classified as a controlled substance and prohibited in competitive sports.
 

3. Dosage, Frequency, Half-Life, and Detection Time

Parameter Details
Typical Dosage (Note: This is based on typical performance-enhancing use, not medical advice): Ranges vary widely, but often 20 mg to 50 mg per day for men. Doses for women are significantly lower to minimize virilization risk.
Frequency Due to its half-life, it is typically taken once daily or sometimes split into two doses per day.
Half-Life Approximately 16 hours. This is the time it takes for the concentration of the substance in the body to be reduced by half.
Detection Time Weeks to Months. The detection window is significantly longer than the half-life due to the long-lasting presence of specific metabolites in urine. Recent anti-doping tests focus on a long-term metabolite that can be detectable for an extended period, potentially up to 40-60 days (or even longer in some cases) after the last dose.
 

4. Estrogenic, Progestogenic, and Prolactin Effects

Effect Category Details
Estrogenic Effects None. Turinabol is non-aromatizable; the chlorine atom prevents its conversion to estrogen. Therefore, estrogenic side effects like gynecomastia and significant water retention are not a concern.
Progestogenic Effects None to negligible. Turinabol is not known to have direct progestogenic activity and does not typically activate the progesterone receptor.
Prolactin Effects None. It does not typically cause the increase in prolactin associated with some other AAS (specifically those with progestational activity, like Nandrolone or Trenbolone).
 

5. Anabolic to Androgenic Ratio (A:A Ratio)
