Turinabol 10mg (Chlorodehydromethyltestosterone) Overview | iRoids Pharma
Turinabol 10mg is an oral anabolic steroid tablet containing 10mg of Chlorodehydromethyltestosterone as its active compound. Commonly known as Turinabol or Tbol, this compound was originally developed in East Germany in the 1960s by Jenapharm pharmaceutical company. Each tablet contains 10mg of the active compound in the standard tablet format widely available in the non-prescription market. At iRoids Pharma, we carry Turinabol 10mg as part of our oral anabolic steroid inventory for customers in markets where the compound is legally available. Turinabol has a documented historical background in competitive sport and a well-established presence in bodybuilding communities. Like all anabolic steroid products, it carries significant health and legal considerations that anyone researching it should understand clearly before forming an opinion about it.
Turinabol was developed by Jenapharm in East Germany in the early 1960s with the specific goal of creating an anabolic steroid that combined anabolic effects with a lower androgenic profile compared to testosterone. It is structurally a combination of Methandrostenolone and Clostebol, incorporating the 4-chloro substitution of Clostebol onto the Methandrostenolone base. This structural modification produces a compound that does not aromatize to estrogen and carries lower androgenic activity than Methandrostenolone. The compound gained significant historical notoriety through its documented use in the East German state doping program spanning from the 1970s through the 1980s, one of the most extensively documented state-sponsored doping programs in competitive sport history.

What Is Chlorodehydromethyltestosterone
Chlorodehydromethyltestosterone is a synthetic anabolic androgenic steroid structurally derived from Methandrostenolone with a 4-chloro substitution incorporated from Clostebol. This structural modification produces several distinct pharmacological differences from the parent compound Methandrostenolone.
The 4-chloro substitution prevents aromatization to estrogen. As a result, Turinabol does not convert to estrogen through the aromatase enzyme, which distinguishes it from Methandrostenolone and most other testosterone-derived oral anabolic steroids. This non-aromatizing characteristic is one of the most consistently referenced pharmacological features of Turinabol in both research and performance community discussions.
Androgenic Profile
The androgenic rating of 6 relative to a testosterone baseline of 100 indicates very low androgenic activity. This extremely low androgenic rating distinguishes Turinabol from most other oral anabolic steroids and is lower than even Oxandrolone’s androgenic rating of 24. The combination of measurable anabolic activity and very low androgenic activity consequently gives Turinabol a distinct position in oral anabolic steroid discussions.
17-Alpha Alkylation
Turinabol carries 17-alpha alkylation, which allows it to survive oral administration and reach systemic circulation without breaking down in the liver during first-pass metabolism. This modification produces the liver toxicity risk associated with oral alkylated steroids. The liver toxicity of Turinabol is documented as moderate to high in clinical and research literature. This represents a more significant hepatotoxicity concern than Oxandrolone but generally less severe than Methandrostenolone at comparable doses.
Half-Life
Turinabol has a half-life of approximately 16 hours. This is longer than most other oral anabolic steroids including Methandrostenolone at 3 to 6 hours and Oxandrolone at 9 to 10 hours. The longer half-life means less frequent daily administration is required to maintain relatively stable plasma concentrations compared to shorter-acting oral compounds.
Historical Background of Turinabol
Turinabol carries one of the most extensively documented historical backgrounds of any anabolic steroid in competitive sport history. Understanding this context is relevant for anyone researching the compound.
East German Development
Jenapharm developed Turinabol in East Germany in 1962. The original clinical intent was to produce an oral anabolic steroid with favorable anabolic to androgenic characteristics for therapeutic applications. Jenapharm held the original patent and produced Turinabol under the brand name Oral-Turinabol for legitimate clinical use in East Germany.
State Doping Program
From the 1970s through the 1980s, East German sports authorities administered Turinabol to athletes in a systematic state-sponsored doping program. This program, later documented in detail following German reunification, involved athletes across multiple Olympic disciplines receiving Turinabol without their knowledge or informed consent in many cases. The scale and systematic nature of this program gave Turinabol a level of historical notoriety that distinguishes it from most other anabolic steroids in sport history discussions.
Discontinuation and Revival
Jenapharm discontinued Turinabol production following German reunification. The compound subsequently disappeared from the pharmaceutical market. However, it was later revived by non-prescription manufacturers who recognized demand for the compound in performance communities. Current Turinabol products including the 10mg tablet format available at iRoids Pharma are produced by non-prescription manufacturers rather than by Jenapharm or any regulated pharmaceutical company.

Why Turinabol 10mg Appears in Bodybuilding Discussions
Turinabol occupies a specific and well-defined position in bodybuilding discussions. Several distinct characteristics drive its consistent presence in performance community conversations.
Non-Aromatizing Profile
Turinabol does not convert to estrogen due to its 4-chloro substitution. As a result, users do not experience estrogen-related side effects including water retention, gynecomastia, or estrogen-driven blood pressure increases from Turinabol use alone. This characteristic distinguishes it from Methandrostenolone and most other testosterone-derived oral anabolic steroids. It consequently makes Turinabol a consistent topic in discussions where a dry and lean physical appearance is the goal.
Very Low Androgenic Activity
The androgenic rating of 6 relative to testosterone makes Turinabol one of the least androgenic oral anabolic steroids discussed in performance communities. This extremely low androgenic rating translates to a significantly reduced risk of androgenic side effects including hair loss, acne, and body hair growth compared to most other anabolic steroids. This characteristic is consequently one of the most consistently cited advantages of Turinabol in performance community discussions.
Lean Muscle Retention
Turinabol is frequently discussed in bodybuilding literature in the context of lean muscle retention and quality gains without water retention. Its non-aromatizing profile and low androgenic activity contribute to discussions about clean and maintainable muscle development compared to more estrogenic and androgenic compounds that produce more pronounced but less sustainable effects.
Historical Significance
Turinabol’s documented use in the East German state doping program gives it a level of historical credibility in performance communities that most other anabolic steroids do not carry. The documented athletic outcomes associated with systematic Turinabol administration across multiple sport disciplines contribute to its consistent discussion in performance contexts.
Longer Half-Life Among Oral Steroids
The approximately 16-hour half-life of Turinabol is longer than most other oral anabolic steroids. This extended half-life means less frequent daily administration is required to maintain relatively stable plasma concentrations. This practical characteristic is referenced in performance community discussions about oral anabolic steroid administration convenience.
Turinabol 10mg Versus Other Oral Anabolic Steroids
Understanding how Turinabol compares to other commonly discussed oral anabolic steroids helps clarify its specific position in performance discussions.
Versus Methandrostenolone (Dianabol)
Methandrostenolone is the parent compound from which Turinabol is structurally derived. Methandrostenolone aromatizes to estrogen and carries significantly higher liver toxicity than Turinabol. It produces more rapid and pronounced effects in bodybuilding contexts but generates estrogen-related water retention and gynecomastia that Turinabol does not. The 4-chloro modification in Turinabol consequently produces a meaningfully different pharmacological profile from the parent compound despite the structural relationship.
Versus Oxandrolone (Anavar)
Oxandrolone does not aromatize to estrogen, similar to Turinabol. However, Oxandrolone carries lower liver toxicity and a higher anabolic rating of 322 to 633 compared to Turinabol’s anabolic rating of 54. Furthermore, Oxandrolone retains active FDA approval for multiple clinical indications while Turinabol has no current active pharmaceutical approval. Both compounds appear in similar bodybuilding contexts due to their non-aromatizing profiles but differ meaningfully in their anabolic rating and hepatotoxicity characteristics.
Versus Stanozolol (Winstrol)
Stanozolol does not aromatize to estrogen, similar to Turinabol. However, it carries higher liver toxicity and more significant adverse lipid effects than Turinabol. Stanozolol is also associated with joint dryness that Turinabol does not typically produce. Both compounds appear in non-aromatizing oral steroid discussions but carry different side effect profiles.
Versus Mesterolone (Proviron)
Mesterolone is a non-aromatizing oral androgen that carries very low liver toxicity due to its non-17-alpha alkylated structure. Unlike Turinabol, it produces minimal direct anabolic effects. Both compounds appear in non-aromatizing oral steroid discussions but serve different primary functions in performance community contexts.
Risks and Health Considerations
Turinabol 10mg carries a significant risk profile. Anyone researching this compound should understand these risks clearly before proceeding.
Liver Toxicity
Liver toxicity is the most consistently documented risk associated with Turinabol use. As a 17-alpha alkylated compound, Turinabol places stress on the liver during metabolism. Clinical literature and research document elevated liver enzymes with Turinabol use. Furthermore, peliosis hepatis has been documented in association with prolonged oral 17-alpha alkylated anabolic steroid use generally. Regular liver function monitoring is therefore essential for anyone using Turinabol under medical supervision.
Cardiovascular Effects
Turinabol negatively affects cardiovascular health through multiple mechanisms. Clinical research and user reports document significant reductions in HDL cholesterol and elevations in LDL cholesterol with Turinabol use. These lipid changes are documented as among the most significant adverse lipid effects of any oral anabolic steroid. Regular cardiovascular monitoring is consequently important for anyone using this compound.
Hormonal Suppression
Turinabol suppresses natural testosterone production through feedback inhibition of the hypothalamic-pituitary-gonadal axis. The degree of suppression varies between individuals and depends on duration of use. Natural hormonal function may require medical support to restore after discontinuation. As a result, the timeline for recovery varies significantly between individuals.
Androgenic Side Effects
Despite an extremely low androgenic rating, Turinabol still produces androgenic side effects in some individuals. These include acne, oily skin, and in genetically predisposed individuals, acceleration of male pattern hair loss. However, the very low androgenic rating means these effects are generally less pronounced than with most other anabolic steroids at comparable doses.
Virilization in Women
In women, Turinabol use carries a risk of virilization including voice deepening, clitoral enlargement, increased body hair growth, and disruption of the menstrual cycle. The documented use of Turinabol in female East German athletes produced significant virilization effects in many cases. These effects may be irreversible with prolonged use. Women researching this compound should therefore be particularly aware of this documented risk.
Detection in Anti-Doping Testing
Turinabol and its metabolites are detectable in urine testing for extended periods following use. Long-term metabolites of Turinabol were identified in anti-doping research that led to retrospective disqualification of athletes in multiple Olympic sports. This extended detectability is a relevant consideration for competitive athletes subject to anti-doping rules.
Legal Status
Chlorodehydromethyltestosterone carries Schedule III controlled substance status in the United States. A valid prescription from a licensed physician is required for legal possession and use. Legal status varies by country. Research the legal status in your specific jurisdiction before purchasing from iRoids Pharma.
