GP Turan Turinabol Overview
GP Turan is an oral steroid from Geneza Pharmaceuticals containing 4-Chlorodehydromethyltestosterone at 10 mg per tablet, supplied in packs of 50 tablets. 4-Chlorodehydromethyltestosterone is universally known in bodybuilding communities by its brand name Turinabol, and is one of the most searched oral anabolic steroids for lean mass and quality gains. Commonly searched as Turinabol, Tbol, T-bol, Oral Turinabol, and 4-CDMT.

What Is 4-Chlorodehydromethyltestosterone?
4-Chlorodehydromethyltestosterone (Turinabol, Tbol) is a synthetic oral anabolic steroid structurally derived from Methandienone (Dianabol) with a 4-chloro substitution that eliminates aromatization. It does not convert to estrogen, meaning water retention and gynecomastia are not concerns from the compound itself. Turinabol is most frequently referenced in bodybuilding communities as a cleaner, drier alternative to Dianabol – producing lean, steady mass gains without the bloat associated with estrogenic compounds. The compound became historically notable through the East German Olympic doping program of the 1970s and 1980s. The 10 mg per tablet format provides flexible daily dose adjustment across commonly discussed protocol ranges.
Why Users Search for GP Turan
GP Turan is most frequently searched in lean mass, recomposition, and lean bulking contexts. Community discussions consistently describe Turinabol as producing slower, steadier, and drier gains than Methandienone – making it a reference point in Tbol vs Dbol comparisons that are among the most searched oral steroid comparison topics. Users also commonly search for Turinabol cutting cycle use, Tbol lean bulk, Tbol SHBG reduction, Turinabol half-life, and whether Tbol can be used solo. The dry, quality gain profile of Turinabol is its most consistently cited characteristic across all community references.
- Main compound: 4-Chlorodehydromethyltestosterone – an oral anabolic steroid that does not aromatize and produces lean, dry gains.
- Product type: Oral steroid tablet, 10 mg per tablet, 50 tablets per pack.
- Common names: Turinabol, Tbol, T-bol, Oral Turinabol, 4-CDMT, Chlorodehydromethyltestosterone.
- Product context: Lean mass and recomposition cycles; frequently compared to Methandienone (Dianabol) as a drier, non-estrogenic alternative; discussed in both lean bulking and cutting stack contexts alongside testosterone bases and other cutting compounds.
GP Turan Dose and Concentration Information
GP Turan is listed at 10 mg per tablet. A pack of 50 tablets contains 500 mg of 4-Chlorodehydromethyltestosterone in total. The 10 mg per tablet format is the standard Turinabol tablet strength referenced in community discussions, providing flexible daily dose adjustment across the range of protocols discussed in bodybuilding communities. Turinabol is consistently noted in community references as slower-acting than Methandienone – producing more gradual but qualitatively different gains – which is reflected in how cycle length discussions differ between the two compounds.
Commonly Referenced Dose Context
Turinabol is referenced in community discussions with a half-life of approximately 16 hours – longer than most other oral anabolic steroids – which is cited as a practical reason for once or twice daily dosing in many community protocols. The longer half-life relative to compounds like Stanozolol or Methandienone means the 10 mg tablet format is frequently discussed for single-daily-dose approaches. Community references discuss Turinabol cycle lengths of 6-8 weeks, positioning it alongside other mild-to-moderate hepatotoxicity oral anabolic steroids rather than the extremely short cycles required by compounds like Methasterone or Methyltrienolone.
- Format context: 10 mg per tablet, 50 tablets per pack – oral administration, 17-alpha-alkylated for bioavailability. Total pack content: 500 mg 4-Chlorodehydromethyltestosterone.
- Half-life context: Turinabol is consistently referenced with an approximate 16-hour half-life – among the longer oral anabolic steroid half-lives discussed in community references. Once-daily dosing is cited as a viable approach in many community protocols.
- Bloodwork context: Liver enzymes (ALT, AST), lipid panel (HDL/LDL), and testosterone levels are the primary bloodwork topics in all Turinabol references. Hepatotoxicity is discussed as moderate relative to other oral anabolic steroids.
- Support context: PCT (Nolvadex and/or Clomid) is referenced as required following Turinabol cycles; liver support supplementation is consistently cited for 17-alpha-alkylated oral cycles; no aromatase inhibitor is needed for the compound itself, but one is referenced for any testosterone base companion.
